Regular Expression Details

Title Test Find Check filename extensions
Expression
^.*(([^\.][\.][wW][mM][aA])|([^\.][\.][mM][pP][3]))$
Description
Matches a file name to be either a .wma or .mp3 file. This can be used to check file uploads to make sure they are of a certain type. Substitute letters where appropriate for specific file types. This is a better solution (I think) than #343. Works in Javascript and C#.
Matches
thisfile.mp3 | tH@tfile.wma
Non-Matches
whatever.exe | somethingelse.mpa | thisagain.wm3 | filenamemp3 | filename..mp3 | filename.wmap3
