Changing legth of file name - How?

Some of my files are not being processed due to the file name being too long. I get the following error message: Error Domain=NSPOSIXErrorDomain Code=63 "File name too long"

So I want to write a rule to shorten the file name, but there is no option like "If length of files name exceeds..."

Any ideas other than manually changing each file name?

A feature like this is in the feature database but can't say if/when it will be implemented. You would probably need to write a script to do it now.

I found a work around.

By automatically moving all files to a new folder after processing, only the file names which were too long are left behind.

I then run a "re-name" command on all files which are more than one day old. They are renamed with the pattern "# extension". (i.e. renamed with a sequential number). I can then process them normally.
