Is it possible to open files directly from the list of the stored items. I want to implement this function so that the user can check the files before they getting uploaded.
If you would like to allow users to open submitted files in an external application via the browsers by clicking on these files (for example), this is not really possible. The browser does not provide sufficient access to the file system to make this possible. As Mark mentioned, Fine Uploader will already optionally generate previews for images. We intend to look into providing client-side previews for audio and video files in the future as well.

My application accepts photographs from end-users. They will most likely select pictures that are recently taken. The initial view of Chooser, which shows the file structure of the user's Dropbox folder is therefore far less useful compared to the Photos view. Is there a parameter than can be passed to make the window opens to that view? Just a matter of saving an inevitable click.
I tried to examine the source code but the library appears to be written in Coffee.
There's no way to open a specific folder in the Dropbox Chooser. You can make the UI a bit nicer by using the extensions option to specify only image file types.
On the project page, it states that multi-file uploads are possible with fine-uploader.
What parameter needs to be set to make this possible?
Is there an example with progress bars?
Nothing needs to be set to make this possible. By default, Fine Uploader supports the multiple attribute on file input elements. You should be able to select multiple files without setting any related options.
Note that IE9 and older do not support multiple file selection, nor does Android.
We are working on our converter site. and we want users to download their converted file. But audio files and other files are just playing on the browser, How can we set all Video/Audio formats downloadable (not just because the browser supports the player for the formats). THANKS.
IMO you should check the MIME types. I think if you set it as binary, it will get downloaded, not played by the browser.
Another approach is to put the file(s) into an archive server side then attach the archive to the response. That way you avoid client playback and potentially decrease download time.
Another possibility is, as most sites do, just show the link and instruct the user to right click and select download. I'd go with other options (as proposed, like looking into the MIME types), but it is still another possibility.
Suppose I have a .NET web application that contains two panes. One pane is a viewer capable of displaying a variety of large file types. The other pane contains an arbitrary list of files, e.g. file1.docx, file2.xlsx, file3.pptx, file4.txt, file5.doc, file6.htm, file7.zxz, file8.exe etc.
The user is capable of selecting any file in the list and displaying it in the adjacent pane when the selection changes, presumably via client-side Javascript. Given the user has selected some file, e.g. file1.docx, is there a way to prefetch/preload some number of files in the list, e.g. file2.xlsx and file3.pptx while the user is viewing file1.docx?
If this could be done in the background with an asynchronous Ajax-like call, it would make the application appear faster for users who went from file to file in sequence. I am assuming that the prefetch call could be smart enough not to attempt to request files that could not be viewed, e.g. exe files.
Any help or examples would be much appreciated.
Use hidden iframes to load subsequent documents after the first click. Use a plugin detection script to check file extension support prior to allowing the click event. If you want to prerender, then use each browsers prefetch API:

Basically, I'm looking for RequestPolicy for Safari. GlimmerBlocker, Privoxy and BFilter etc, those work well but none of them support "block 3rd party elements" feature.
I use GlimmerBlocker, and to imitate (barely) the function, I mainly put this code to filter script flooded website.
replace(/<(script|noscript|iframe)([\s\S]*?)<\/(script|noscript|iframe)>/img, "")
However I'm tired of repeating creating filters for each websites. Vice-versa, whitelisting will be the same.
If anybody had an idea to solve this, that would be so great. Thanks.
I made this proof-of-concept Safari extension to block external resources (images, objects, and scripts, but NOT link elements, such as stylesheet links) until allowed. It has a bare minimum number of features, but if you are interested, I might develop it further.
I say "external" and not "third-party" because I don't know to tell reliably if a resource is third-party or not. This extension just blocks all resources that come from a different host than the web page. As a result, it blocks too many resources by default.
You can right-click a blocked image and use a context menu command to whitelist the image host. If the blocked image didn't have a specified width and height, it will be invisible, so you won't be able to right-click it. (To remedy this, I will need to add code to make the empty image visible as a box.)
The whitelist command does not show up for blocked plugin objects (such as Flash objects) or scripts. I will have to add code to deal with that.
You can also whitelist the current site itself, meaning that all external resources will be allowed on that site. Again, this is done with a context menu command.
As yet, there is no way to remove items from either whitelist. This can be added.
Download the extension from here.
You can extract the source files from the extension package using this command:
xar -xf PartyPooper.safariextz
You are welcome to do whatever you like with the source.
