Tried that first but it gave the same error. So I removed the -name, thinking it would not look for the file twice.

Are you sure that 20 chars will contain the relevant part of the files?
This sure was faste, but it's not generating the correct new filename. I'm not familiar with ${file:0:20}. What does this do?

Oh I see what it does. I just need to modify it to 26 and it works.

Many thanks.
