Drag and drop is not working for files with prc extension but if i click the Select File(s) button and then browse and select the file it works. Also there is no error message.

Drag and drop should work for *.prc files.

Go to Assets, take any file with prc extension and drag and drop to upload.

Thank you. I can reproduce it. Seems that drag and drop does not accept file without a known mime type.

Thanks for the response @Sebastian, so when can I expect this bug to get resolved?

I hope soon, but it does not have the highest priority, because there is an easy workaround.

Thank you @Sebastian
