Because we want to be more than a simple file hosting site, we added some new features that will make the process of installing and extracting files easier.
The first feature is standard filenames: revisions now have a standard filename that is constructed using the resource name and ID. This results in much better organisation and less file clutter.
The second feature is that any revisions that will be uploaded from now on will be automatically converted to the ZIP format.
We do this because it's simpler for people to extract ZIP archives, since it's pretty much supported by default on every platform. No more nasty RAR or other alien filetypes to bother with.
You can still upload files with .rar, .7z and so on, but they will be automatically converted to .zip after the upload finishes.
Please write to us if you have any concerns or questions.
