I have a chm file that I can open at home. I use windows XP at home and at work. However, when I open the file at work it doesn't show the contents of the file. It properly shows the TOC for the file though. Any ideas pls?
Try to right-click on your chm file and select properties. You will see an "Unblock" button. Click on it, it should solve your problem.
Other than what Nicolas suggested, you may not be able to see contents of a CHM that you open over a UNC path. If that is the case copy the file to a local drive.
just go to power shell and run it as administrator,
cd your folder
and use the following command
Unblock-File '.\filename.chm'
On Windows 7 copying the file locally and unchecking the file opening warning message worked.
I had the same situation, on a Windows 10 (VMware) system. I had to move the file to a local drive as suggested by another poster AND THEN uncheck the file opening warning message. Opening the file gave a "Open File - Security Warning" message, with a checkbox at the bottom "Always ask before opening this file". Until I unchecked that box, only the TOC showed. After unchecking, the contents showed properly. HTH someone else!
Open command prompt and run as administrator.
Go to file location, input the file name and press enter.
It should open the file and view contents in chm viewer.

It appears a lot of people have this problem but were unable to track down a solution. There are apparently different levels of authentication. Most articles I read tell you to set the MaxAllowedZone to '1' which means that local machine zone and intranet zone are allowed but '4' allows access for 'all' zones.

This is how my registry looks (I wasn't sure it would work with the wild cards but it seems to work for me):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="\\\\<network_path_root>;\\\\<network_path_root>\*;\\ies-inc.local;http://www.*;http://*;https://www.*;https://*;"
As an additional note, weirdly the "UrlAllowList" key was required to make this work on another PC but not my test one. It's probably not required at all but when I added it, it fixed the problem. The user may have not closed the original file or something like that. So just a consideration. I suggest try the least and test it, then add if needed. Once you confirm, you can deploy if needed. If the 'Unblock' method does not work, or you do not see the option, this should. Good Luck!
P.S. Another method that worked was mapping the path to the network locally by using mklink /d (symbolic linking in Windows 7 or newer) but mapping a network drive letter (Z: for testing) did not work. Just food for thought and I did not have to 'Unblock' any files. Also the accepted 'Solution' did not resolve the issue for me.
Your CHM File Has the "#" Hash Character in the Filename or in the Directory Name. Please remove "#" and you will be able to see the content. If still you are not able to see then please visit following link: https://www.helpsmith.com/chm-cannot-be-displayed.php
Windows block *.chm files came from another computer fore security reason. Click right mouse button on file and set unblock checkbox see.
If someone need, there is a web page: http://topdf.com/ where is possible convert a chm in to pdf. I tested it with a chm of ~18MB and 615 pages. I was able to got a pdf with a hyperlinked contents table.
I was experiencing the same problem.
I read that the .chm file only worked on NTFS.
My file was on a cloud network drive which is not NTFS, so I copied it locally and the problem was gone.
Use SumatraPDF. It opens .chm files.
I had same problem and zipped the file then open it from inside the zip program.(I use 7-zip)

Almost every time you save a web page from a web browser to your local computer a PAGENAME.html (or .htm) file is created and a folder named 'PAGENAME_files' that contains resources specific to that page.
If you copy/move/delete either the folder or the .html file Windows automatically does the same operation the other file as well.
This behaviour also happens if you create a file named 1.html and a folder called 1_files.
How does this link happen? And why does it work only with web files?
This is a shell feature, not a file system feature. The shell copy engine just looks for a folder with the same name (plus a localized suffix) when copying/moving .htm[l] files.
This feature is called Connected Files and is documented here.
It's a built-in linkage in Windows.
Open up Explorer (not IE, Windows), Tools, Options, View, then in Advanced Settings there'll be a "Managing pairs of Web pages and folders" section.
If people are stuck and ended up here to find how to unlink, here's an easy trick : on Windows 10, I couldn't find how to unlink a .html file from its associated media folder, so I deleted both of them, and in the bin I restored only the .html file and it was then restored and unlinked from its folder.
It is a good question.
Under Windows 7 I managed to solve forced links by simply renaming the file.
I think it is the easiest way.
In the google chrome version 30.0.1599.101 m I am not able to save the changed js file.
On saving the js file I got yellow triangle symbol with "change to this file were not saved to file system" message.
I know this used to work in older version
I am using windows-7 64 bit
Click on the cog in the developer tools window (lower right corner)
Go to workspace and add the directory which you would be working on.
This is to accidentally prevent you from modifying files that you did not intend on changing.
Happened to me too. After picking the workspace directory, I also mapped the file from the "Source" panel of Devtools to its filesystem equivalent (using right-click on the file, from the file tree). It solved my problem.
In chrome > 63, accepted answer option is disabled.
In later should be done through workspaces.
Tonight, I accidentally managed to fix this problem, just open the file on the disk and save it with a simple change even with a space.
Refresh the page in Chrome, Chrome will link it(The file) to the disk.
Using Ctrl + F5 to clear the browser cache worked for me.
I found nothing in "workspace" that seemed relevant, and other things people listed didn't help either. What helped was to go in dev tools, where it says Pages, Sources etc., there is also Overrides (duh :)), I chose it, it said "Select folder for overrides", I did, and then also clicked "Allow" on Chrome asking for confirmation. That's it, after that I was able to save the files, the overrides worked.
Ok, my case might be a bit different but I will share my experience on what I was facing that caused to this warning and how I solved it.
I was trying to check a certain strange behavior on a React app for video streaming, so I opened up Developer console, enabled local overrides and tried editing the js file, immediately upon saving I got the warning “Changes to this file were not saved to file system”.
Note the message at bottom right “Source mapped from app.bundle.min.js”, this indicated that this is not an actual file but a mapping from the app.bundle.js (Webpack bundle)
So I moved to editing the app.bundle.min.js, I searched the appropriate string I was interested in from the mapped file (react-dom.production.min.js) and searched it in app.bundle.min.js
Again I got the same warning but I noticed the “app.bundle.min.js” file was fetched using a url parameter ?v=4900, I decided to remove it to check if that was the culprit causing the issue, to achieve that I modified the index.html file and edited the script tag that was fetching the js file from
<script src="libs/app.bundle.min.js?v=4900"></script> to <script src="libs/app.bundle.min.js"></script>
After that I forced refresh the page (Shift+F5, normal refresh didn’t work), tried modifying and saving and Jackpooot!! (Take away: You can’t override files fetched with a url parameter). I then was able to beautify, modify and override the app.bundle.min.js implementation and achieved what I wanted.
On Chrome Version 109~ :
Go to F12 > Sources Tab > Overrides (You may need to click the chevron next to Page)
Select/Create a folder to contain Overrides
You can now right-click a file or editor window & save it for Overrides
Image of sources tab where Overrides is located
Something to note: if you are making dynamically loaded JS available in devtools via the helpful: //# sourceURL=Example.js comment, this network to local mapping will not work.
Note: Notice the "//# sourceURL=dynamicScript.js" line at the end of dynamicScript.js file. This technique gives a name to a script created with eval, and will be discussed in more detail in the Source Maps section. Breakpoints can be set in dynamic JavaScript only if it has a user supplied name.
https://developer.chrome.com/devtools/docs/javascript-debugging
When you're using sourceURL, you can't actually find the respective JS file in the Sources tree where you might expect it to exist. It is available to open via the "no-domain" tree, however (or quick open with CTRL/CMD+P).
I'm still looking for a solution.
The easiest solution I found to this problem:
(keep in mind, I was manipulating an html page that lives on my machine)
open the associated html page from the command line so the page displays
for mac, that's simply $ open <name>.html
open Dev Tools
open Sources tab
in Page, open a new .js file there with whatever name you need
write in some text and save
This worked for me. Yes, I had to create a new .js file, but my directory locally recognized it was there when I pulled it, and my editor was updating in real time with the dev tools each time I saved either. At that point, my editor and the dev tools source tab had become one thing.
Currently on Chrome 100.0.4896.60 (Official Build) (x86_64).
I've got a js file with source maps; the override has always been spotted.
I'm able to override the map file (which won't work though for the debugging purpose) and the index.html file.
Apparently my issue is related to minified js with source maps.
Seem to work in relation to the chrome version installed.
I tried the following attempts but didn't work:
remove cache
disable / enable override
add the dir to the workspace
install chrome canary
To debug then I've tried:
build my file.min.js to test. In my case was production/file.min.js
start a npx http-server in production (cd production && npx http-server) which open to http://127.0.0.1
override index.html to consume http://127.0.0.1/file.min.js
Interesting considerations:
When i was doing basic overriding i had to replace the file manually all the times.
Now, I've got a watch task going on and i can basically refresh the page.
I can see as well the source map update.
It's simple! Right click on your page, Go to Inspect, go to the Network tab and tick the check box 'Disable cache'. Reload the page and you will see the effect.
I accidentally deleted a HTML file with dreamweaver. I really would like to get this file back, my backup was not ok. So I would like to retrieve the file using the cache of my browser Chrome. I Googled and found this: LINK But it doesnt work for me, when I download the file and look at it in Notepad all I see is strange characters.
What else can I try to get my file back with Chrome cache?
NirSoft's ChromeCacheView worked perfectly for me.
http://www.nirsoft.net/utils/chrome_cache_view.html
Note that the option to restore the actual files is not that obvious. F4 does it.
It would not be easily extractable from it's hexadecimal representation.
I have recently created a script for extracting files from Chrome and Firefox cache. Check it out at this gist.
See the usage guide in this post.
What you download on this site is a gzip file, if you open that in notepad you will get much the same as on the chrome://cache site. You need to extract it with 7zip or a similar tool first.
I worked on a chrome extension and uploaded it to chrome webstore and everything went well, I installed it on my Mac and on my Ubuntu machines in chrome it worked fine and installed. But when I try it on Windows machines, after download it popups a error message saying "Invalid Package, Can't unzip the extension".
Can any one tell me why or what might be the cause for this OS specific issue. Does it have anything to do with the permission or anything with respective folder name or content? The folder name or the extension name don't have any special characters and the previous version was fine.
Thanks in advance.
This is because there a file inside the package with a Windows invalid character in name or there a corrupted file. In my case I've tried to download the CouponsHelper extension and this error was displayed too.
I downloaded the CRX file manually and opened it with 7Zip. In the folder had a file named Icon. When I try to extract using 7Zip an error occurs too.
Note on the screenshot that there an invalid char in Icon file and that it is zero sized (possibly corrupted).
Another cause of this problem (Error: could not unzip extension) might be that you include the root directory in your zip.
You should zip all files in the same level of manifest.json.
Example
-yourappfolder
|_manifest.js
|_popup.html
In this case you should zip only manifest.js and popup.html, instead of zip the entire directory yourappfolder.
In other words, in your zip file you should NOT see the yourappfolder directory.
So the trick it to compress all the files within the folder not the folder itself.
NOTE: If it's saved in Google Drive (local syncing) this well mess it up too. Drive attaches little icons to folders that show up as unknown.
So remake the folder outside of Google Drive.
That's what was messing mine up after the "only compress inside of folder" fix.
I had the same problem but the reason was different.
I found that there is an image which has a name that is too long. When I replaced the name with a shorter one and built new package, it installed successfully.
I hope this helps anyone may facing the same problem.
A quick Google only turned up one possibly useful result but I wasn't sure if it would help.
Is that error message exactly what you see (i.e. word for word)? I couldn't find it in the code.
I may be wrong but I think this could be the code responsible for the error. Unfortunately, the zip::Unzip call can potentially fail for a number of reasons and only provides more details in the logs. I'm guessing such logs output to this location (Windows XP);
%USERPROFILE%\Local Settings\Application Data\Google\Chrome\Application\debug.log
None of this information may be useful to you but I thought I'd show you my investigation :)
Have you tried to install the extension again and do you have administration rights (not sure if this would have an affect here)?
I had the same problem but it was rejecting it because either the file was too big or the paths were too long (Windows...), which was because I accidentally included my entire node_modules directory in the .crx file.
It could be caused by a lot of things.
For me, the problem was having .xcf (Gimp) files inside the package.
The extension loaded fine when unzipped manually but showed the "couldn't unzip" error in when loaded from the Chrome Webstore.
I had problems with zipping with MacOS. There was a bunch of hidden files in the zip.
Using Windows solved it but probably taking not the default zipper in MacOS should do the same.
I had a similar problem.
My solution was:
unzip the CRX to a directory...lets say called freddy123
Rename "_manifest" to "manifest"..i.e remove the underscore.
Chrome->settings->More Tools->Extensions (Check Develop Mode Check box)
Load Unpacked extension (select freddy123 directory)
This worked for me.
I have a Web application that is hosted locally on Websphere. In the application there is a link to a .doc file located on a windows server.
CIT
The link was been working for years, but suddenly stopped working on all computers on the network. When I click the link, nothing happens. I checked the files path and name, and nothing has changed. The interface is viewed using IE8.
Does anyone have any clues onto why this isnt working or where I can look to resolve this?
edit: i have just noticed that the file (CIT_.doc) has been saved in the same directory, could this have an effect on it?
I'd imagine one of the following has occured:
The file has been moved or renamed
The K: drive has been re-mapped or other wise modified to a different location
A popup blocker is tampering with the link (because target="_blank")
In other words you need to manually check that file location within explorer, you also need to try a different browser.
Also you need to change the link to:
CIT
See here for the reason, you may also need to URLEncode it.
It probably has something to do with security settings that your network administrator has recently setup, seeing as the m.edmondson's answer does not work. Try it in another browser besides IE.
