disabling upload filename changing

Hi all,

I was wondering is there any way to stop WordPress from changing the filenames on uploads done thru the write post panel? It’s removing any extra periods in filenames which I realize isn’t ideal to have but would like to preserve them for file version numbers. For example, “file-version-1.0.zip” becomes “file-version-10.zip” once uploaded. Do I need to just ftp instead? Any help is appreciated, thanks.
