changing the list of allowed files in a file upload window

is there a way to change the list of files in the file upload window using js? I know there is another thread here talking about that, but it doesn't answer my question as it's using plugins, whereas I'd like to know if it's possible to do it without plugin. In the browser I'm using the accept attribute already so the files displayed when you hit "Browse" are already filtered but I want to change the list of files in the drop down menu and have, in addition to All files, the other files included as values of the accept property. Is this possible with no plugin?
thanks

Dojo Upload file from dijit Tree

I'm trying to reuse someone's code where am getting list files from a dialog. From the list when I choose a file, I can get the name of the file and other details. Now I need to upload this file once I get it but I've looked around but can't find anything providing such solution, the only thing am coming across is dojo uploader and the like. I just want to be able to upload the file manually and also be able to use it as when I receive a file from dojox.form.Uploader.

Uploading html file generated from R-animation package to wordpress

I created a HTML file using the animation package in R. Now I'm trying to upload the resulting HTML file to a wordpress blog but don't really know how to make it work. It seems like I might need to upload some js or css files too but am not sure. Also, it seems like I might need to upload the original data files as the HTML file is 2.5kb and the original CSV file is 2500kb. Any suggestions would be appreciated.
I think I have addressed this issue in ?saveHTML if you are using the latest version of the animation package (the second paragraph in the Note section). Perhaps it is still not clear (I'll improve it in the next version), so let me explain it here:
What you need to upload are: the HTML file, the image folder, js and css. The CSV data is not required, since the animation is independent with the data now.

Download multible files with JavaScript(one Download)

I generate a HTML page with VB.Net which stores several pinks to files. These links are formatted with JavaScript looking like the Windows-Explorer with folders and files. The problem: There are only download links for the files, not for Folders. A folder can contain Subfolders ,a List of Files or a combination of both. So if I want to download a folder, I have to click manually on every file-link. I have not the possibility to insert PHP or another Server-side language.
my question now is:
Is there a client side way to Download them by click on a Folder? I prefer Javascript but If it isn't possible Flash will be ok also.
What you could do is, link the folders to a special ASPX file. In this file, just create a ZIP with all the files inside it, and make the browser download that ZIP file. I think it's the easy way to accomplish what you are trying to.
With Javascript you could open several windows, one with each file downloaded. But I don't think it will please your users.
There is no way in Javascript and as far as I can tell, theres no way to do it in Flash either. A server-side zip is going to be your only way.
