using regex to extract file extension

[OEvangelista]

Hello, 

I have the following filenames:

   aaaaaaa.xlsx

   bbbbbbb.csv

   ccccc.pdf

I am pretty new using the regex tool.

How would I create the Regular Expression to parse the above filenames and just show the file extensions (i.e.. xlsx, csv, pdf, etc.)?.

Thanks

@OEvangelista ,

Answer:  You wouldn't.

You would use this function:  FileGetExt(Path)

Cheers,

Mark
