using regex to extract file extension

Question

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
