I'm developing a Chrome application where I want to do basic stuff with currently downloaded files(mostly I want to move them to a new location using an application or extension whichever is possible).
I'm able to get access to the image, audio, video file using the mediaGallery API of Chrome apps. Is there a possible way I can get access to and being able to move other format file from their current location to some other location using Chromium apps?
You certainly read the contents of any directory that the user has given you access to. And, once the user has done this, you can retain the entry so on subsequent executions you don't have to keep asking the user to select the directory. Then, once you have a file, you can use the file API to manipulate it.
This is in principle all the media API does, except that it comes with knowledge of some built-in media directories.

We have an SSRS 2012 report we have used URL access in order to automatically save to CSV upon running. This works fine, However, now I am told they want to force the report to save to a specific folder location for security reasons (they don't want it being saved to desktop) instead of allowing the user to save wherever. Is there a way to at the very least force a default location using URL access? Assuming this cannot be accomplished purely through the URL any suggestions for an alternative method?
You can find all of the applicable URL parameter commands here in the MS documentation.
That being said, there is no reference to the save location for the export render command that you are using to generate the CSV files. This makes sense because when a website serves a file to download to a browser, the location that the file is saved is actually a browser setting (IE instructions to change location)
I see two possible options:
Utilize a GPO to target the specific users and modify their registries to set the default download location (note that this affects everything they download). An example of this tutorial can be found here.
Use a Windows File Share subscription. If you view the report properties and click 'Subscribe', you can setup a file share delivery on a scheduled interval and export as a csv. Note that this is a schedule delivery though and obviously won't work if you users need to ad-hoc run the report on their timing.
My requirement is to show a panel where I list the local system directory, from where I drag and drop the files inorder to perform operations on it.
In HTML5 the FileSystem API is available , but most of the browsers are not supporting.
Is it possible by using input type as file? Like we browse and select a directory, then we can see the list of files and their details?
As the previous commenters correctly noted, this is not possible because it is considered a security hole. Think about a malicious script that could read out everything on your local file system just by visiting a web page.
You can however implement file drag-and-drop like this: https://github.com/moxiecode/plupload
My chrome app needs to save a file with human-readable or standard format such as SQLite (It should be readable outside Chrome).
Is there any API suitable for this purpose?
Some files with .localstorage extension (SQLite format) are in Chrome\User Data\Default\Local Storage folder. Is it possible to create such files by the app?
Edited: The app should not ask user for extra permission.
Thanks for your consideration.
chrome.fileSystem API is what you need.
You will need to ask the user at least once where to save the file, but then you can retain the entry to write again to the same file/folder.
There is no way around asking the user to "escape the sandbox".
You'll want to use the Quota Management API. This is per-origin storage, and you request specific amounts of quota.
It sounds like you also want your users to open the files directly? There's an HTML5 filesystem explorer Chrome app that you can use. It'll show you the files, and you can figure things out from their URLs (e.g. I'm currently using filesystem:http://localhost:8000/temporary/bar for a local experiment).
Or are you looking for something more user friendly? I think you have to use file save in that case, the same way Google Drive does.
I am building a chrome app for Digital Signage where I need the user to select some files from a particular folder (preferably in the app's directory) i.e audio, videos, photos which should be created by the app on install.
The sample code provided by Google requires that the user navigates to a folder like this
chrome.fileSystem.chooseEntry({type: 'openDirectory'}, function(theEntry) {
if (!theEntry) {
output.textContent = 'No Directory selected.';
return;
}
// use local storage to retain access to this file
chrome.storage.local.set({'chosenFile': chrome.fileSystem.retainEntry(theEntry)});
loadDirEntry(theEntry);
});
However, my app simply needs the name of files in that (say Video) known directory for the user to build a playlist, rather than actually selecting a video file.
Is this supported in chrome.fileSystem API? Any pointers to how I cold get this done?
It sounds like you should be using either the app's sandboxed file systems, or the app's install folder itself.
The sandboxed file systems allow the app to store whatever data it wants, in whatever structure it wants. There are two to choose from: persistent or temporary. Temporary may be cleared at any point in time. To use these check out this article. Some of its code may be out of date with the spec. Note also apps need to request the unlimitedStorage to use these.
The install folder itself can be used in a read only way. To do this you use chrome.runtime.getPackageDirectoryEntry.
I have a Air/Flex desktop application and I'm trying to create a component within the app that can view files on the web server is is already connected to. It just needs to access one particular folder that will contain PDFs, Images & Word documents. I also want the ability to click on the files and having them open in their default desktop applications.
Is this possible and how would I go about doing this?
It's possible but not with your Flex/AIR app alone. It cannot view files/directories on server by itself but it can communicate with your server via webservices, AMF, or any other back end based service. Typically the back end reads the folder and send this information to your app. Your app can open those files in corresponding app but only if those files are available on disk so your app will have to download them prior to opening them.
Every Application has different needs but I myself usually save anything to a desktop or you can use the App storage container as well. As I use only the desktop I download what is needed OR been asked for, and the visitor has the choice of keeping it or if not needed it gets automatically deleted! this way you can use whatever PDFs, Word, Images etc. use read and write (re-write) as well as creating PDFs on the fly with Images, text etc, and that way a visitor also can print directly at his or her own leisure. regards aktell
