Current Behavior

When I go to a folder and click the "Download" button, it asks which kind of archive I want the download to be.
I pick .tar.gz or .tar.bz2 and neither works, it always offers a .zip file.

Expected Behavior

I expect it to offer a .tar.gz download if I pick that. Instead it always offers a .zip no matter what I pick.

Steps to Reproduce

1. Navigate to a folder in filebrowser
2. Press the download button (a down arrow) near the top right
3. Pick .tar.gz archive
4. It offers to download only a .zip

Anything else?
