Hi, i upgraded a website to 2.4.0.
Now I can't upload .f4v Videos to the assets folder anymore (with DOM installed).
If I upload the file with a different extension and then try to change the file name I get the an error that the Extension is not allowed an a list of valid extensions. How can you change, extend that list?

[User Error] Uncaught ValidationException: Validation error writing a File object: Extension is not allowed (valid: , ace, arc, arj, asf, au, avi, bmp, bz2, cab, cda, css, csv, dmg, doc, docx, flv, gif, gz, hqx, htm, html, ico, jar, jpeg, jpg, js, m4a, m4v, mid, midi, mkv, mov, mp3, mp4, mpa, mpeg, mpg, ogg, pages, pcx, pdf, pkg, png, pps, ppt, pptx, ra, ram, rm, rtf, sit, sitx, swf, tar, tgz, tif, tiff, txt, wav, wma, wmv, xhtml, xls, xlsx, xml, zip, zipx).

This actually isn't a DOM issue. It looks like SS is validating file extensions in 2.4.. see File::$allowed_extensions

It's a public variable, so you can probably just modify it with File::$allowed_extensions[] = "xxx";

I'm glad I came across this... I am having the same problem uploading a file with userforms and I'd like to change the allowable extensions. Is there a way to add a wild card so that any file type could be uploaded?

Has anyone found a solution to this problem? My assets folders includes files in lots of different formats, e.g., .cpp, .lha, and I can't even save the folder name right now. I need to either be able to add valid file extensions, or disable extension checking for just the assets folder.

I ended up using the SWFUpload module--it didn't restrict my file types. I was using an upload field via userforms module before.

Switching back to the SWFUpload module wasn't appealing, so I simply added the file types that I needed to sapphire/filesystems/File.php's allowed_extensions variable.
