I agree that you should be able to upload files named 
However you are wrong assuming that only the folder name matters, because 
the (unbelievable ugly) archive format zip defines that if there is only one 
folder, then the contents of that folder shall be extracted instead of the 
Thus any directory disappears during unzipping which makes it impossible to 
get the extension name from the extracted folder.

Therefor the file name is parsed to get the extension key. The parsing is 
defined so that anything before a three numbered version separated by dots 
or dashes forms the extension name.

Blame it on Microsoft who are not able to ship other archive 
binaries/algorithms besides zip.

Wrong :)

I already pushed a change for this issue.

BTW, there is no reason to discuss every issue in the list before someone 
can answer you on the issue.
