Revising TRIM formula to also remove file extension

I am currently using the following formula to extract the filename from a file path:

Filepath:
C:\Program Files\xxxx\zzzz\tttt\iiiiiiii\ooooo\wwwwww\YYBG-POP-7E.ai

Formula:
=TRIM(RIGHT(SUBSTITUTE(A2,"\",REPT(" ",LEN(A2))),LEN(A2)))

Results:
YYBG-POP-7E.ai
YOBP-QRT-4G.doc

I would like to revise the formula so it also removes the file extensions, which are either 2 or 3 character extensions, so that the results would be:

YYBG-POP-7E
YOBP-QRT-4G

Thanks!
Andrea

Try this version

=TRIM(RIGHT(SUBSTITUTE(LEFT(A2,FIND(".",A2)-1),"\",REPT(" ",LEN(A2))),LEN(A2)))

Hi Barry,

It does the trick! The only tweak, if possible, is to hide the #VALUE if the cell in Column A is blank. Is that feasible?

Thanks,
Andrea

Assuming you are using Excel 2007 or later you can just wrap the formula in IFERROR like this:

=IFERROR(TRIM(RIGHT(SUBSTITUTE(LEFT(A2,FIND(".",A2)-1),"\",REPT(" ",LEN(A2))),LEN(A2))),"")

that will return a blank instead of an error.

In earlier versions you could use a simple IF like

=IF(A2="","",TRIM(RIGHT(SUBSTITUTE(LEFT(A2,FIND(".",A2)-1),"\",REPT(" ",LEN(A2))),LEN(A2))))

That specifically returns a blank if A2 is blank

Perfect! I'm using Excel 2010, so the Excel 2007 version did the trick. Thanks so much...
