I have an page with some forms. All the links work fine in IE. They open in a new tab nicely when the hyperlink is click by the user; however, I realized that when Chrome is use the link doesn't open. I keep clicking but nothing opens. The only way of opening the file is copying the hyperlink, opening a new tab in Chrome, paste and go.

Is this something that browser do? Because I tried it with FireFox and doesn't work either?
It there a way of going around? without installing anything in the browser? Because my user loves Chrome.
Thank you in advanced for the responses.
You can't access to files outside your server or "SandBox", sandbox include the files that user push to the browser or to your server.
If the access from browser to a pc files from web pages was possible, it would be a security problem.
The answer is that you can't with your approach and more importantly you shouldn't. Chrome behavior is in fact the right behavior and it protects you from having malicious users and/or scripts accessing your local resources.
The FILE protocol will access local or defined network named resources which will not be available to a remote user that visits the same page. In other words, you may have outsideserver mapped as a network resource/drive but someone else will not (This does not apply to IPs)
Here's what you can do:
Move the code to a server side script(php, asp, etc) and stream the file back out. Found a quick example here on SO. I did not verify it though. Streaming a large file using PHP
Install a webserver on outsideserver and map a new site to the shared folder. You can then reference it via http (http://outsideserver.com/form1.pdf)
Use the below extension for chrome. It will work.
Enable local file links
Below both options are working and tested.

In my app I'm viewing a list of files on the local machine (their paths are fetched from DB). When a file is being clicked, it should be opened. I tried the following with no success:
FileName
When the user clicks the link above, nothing happens. When using chrome, I can see the following error message in the console (on firefox there's no message):
not allowed to load local resource
I have read this question, and understood that:
Mozilla browsers refuse to follow file URLs on a page that it has fetched with the HTTP protocol.
I also understood and that this feature was implemented in other browsers as well.
The presented files are not located in the server, but on the local machine. So I can't use a relative link (right?). Is there anyway to bypass this and create a link that opens a local file?
You cannot access local resources from a website served over http because it is a security concern. Think of what would happen to your machine if any website could access files on it. You'll have other security restrictions for serving data from a different domain from your domain as well.
What exactly are you trying to accomplish by accessing a local file? Giving additional insight into the reason might get you more useful suggestions. Otherwise, the answer is that you can't and shouldn't do this.
Background
I'm writing an excel app using the Javascript API for Office. (Office 2013). Inside that app, I have several links to folders on my computer/server, which I want to access from the app using the file protocol.
I've tested the file protocol with a dummy HTML file, using this link:
C:\Users\User\Desktop
It works perfectly, opening up the Desktop folder. I've also tested using a networked drive, and it works as well.
Problem
When I add this dummy link into an HTML page in my Excel web app, clicking on it does nothing. When I right click -> Open, IE11 opens a new instance (which doesn't happen with mailto: links), and asks if I'd like to give permission. After I do give permission, the folder is opened.
Goal
I want a single left click to open the folder location without the permissions box ever popping up. Worst case, I want to be able to have the user open a dummy link once during app setup and then once permission is given avoid having to right click -> open.
Question
How can I accomplish the goal here? Is Office just locking down the links?
Update
The primary issue I've found out is that the site I'm hosting the app on wasn't a trusted site. Links using the file protocol only work on intranet and trusted sites. So the only question now is whether the Office store location is trusted.
The problem here lies in the way that Office Apps work. A manifest file is stored with the Office Store, and that is what users download. That manifest points to a server location that the app developer specifies, and that is the location from which the app is served. That is the location which must be added to Trusted Sites in IE.
Therefore to get the File Protocol working smoothly, I'd need to include instructions with my App on adding my hosting server to the Trusted Sites domain, and I'd have to avoid ever changing domains.
I have an html app, with html, js, css and images, which I need to distribute on a pendrive for Mac and PC. When users open the app, however, they're receiving security errors in their browser.
I'm looking for a simple solution to this, but I can't find any easy way of opening a html app from a pen drive. Any solutions would be greatly appreciated.
EDIT:
You are right The error come from ajax local call to xml files.
Anyone has a solution ?
In reference to question - How can I make local ajax calls to xml files when distributing my html project locally?
The users who are having problems is probably due to the browser they are using and the state the browser was initialised in, as some browsers by default allow local ajax calls to files and some don't.
You have two options.
To your users specify a browser to run it in (for example chrome automatically disallows local ajax calls however if started with the flag --allow-file-access-from-files it will allow this behaviour)
Host the files on a web-server either in the flash drive or externally.
I think I have the solution.
With the mongoose portbla web server, I can launch a small web server without installation on mac an pc.
I just have to find how to put my page as default.
I wish it will help someone with the same problem.
Thanks for you help in advance,
I am building a very simple web page , (a single page) with links to e.g bbc.com, cnn.com etc, (this works fine)
now i need to create diff links on that page to various location on our internal shared drive, which is already map to user pc from the server (running win server 2008).
wen users who's systems are not connected to our domain try to access the shared drive (after a shut down) they are always prompted for username and password which then give them access to the drive.
my ques now is how do i create this link on my html page so that when users click it. its opens (\10.10.0.1\k\Shared\HR) in windows explorer and not in the browser which it does now.
<li data-tags="Logo Design"><img src="images/portfolio/thumbs/image(5).jpg" alt="Illustration" />
this is the line i use.
i have read this links but they dont look to ans my ques, or i dont just understand what to do,

Thanks for you help, I hope I have provide all the info needed to help me with this.
we all use chrome cause of google drive
This will not be accomplished by any default browser configuration that I am aware of, as using file:// references would typically cause the browser to try to launch the file. Maybe search though Chrome plug-ins to see if something is available there to override default browser behavior.
I am working on a replacement application to a legacy application. Due to certain design limitations of the legacy application, 'attachments' are stored as a String path in our database (generally files stored on a windows shared drive). The legacy application can then 'open' the attachments by opening a windows command shell and executing the given path.
The legacy (Oracle Forms) application is being phased out by a JSF based J2EE web application. The new application needs to be able to 'open' or link to these legacy attachments somehow. Is this even possible? I have attempted to use file:// URLs, but there are lot of caveats with using them. They only work on remote hosts in IE, firefox/chrome (and other modern browser I assume) prevent local file URLs.
Working only on IE is something that can be lived with for this particular feature. I further ran into an issue with file paths with spaces. For some reason if IE encounters a filepath with spaces in it, say
C:\Documents and Settings\user123\My Documents\testing\someFile.txt
it refuses to open that link. The browser automatically replaces the spaces (' ') with its URL Encoded '%20'.
The associated link I am attempting looks like:
link
Is there something simple to this I am missing? Or is there any easier way of doing this?
I wasn't quite sure what to tag this as so feel free to retag as necessary.
After some extensive testing I have reached the following conclusions:
Only IE will open file:// links that are on a page from a remote host, Other browsers will block them outright and nothing will happen when a user clicks on them.
IE will only open file:// URLs that point to a file that resides on a network drive
If a user clicks on a file:// link pointing to a file on the user's local drive, nothing will happen and they will get no error.
If a user clicks on a file:// link that points to a network file it will open in the browser, if possible.
If the file:// url points to an invalid location (unmapped network drive, file on a network drive that doesn't exist), Windows will show a popup error.
Spaces in the file path needs to be URL encoded with %20
Hopefully this helps someone else out who's looking for information on file urls.
If you use double quotes (") around the path to the file (you will probably need to URL encode these as %22), windows will be OK with the full path:
link
