I have a file that is imported into Laserfiche from a shared drive.  A sample file name is "B1234 abcderfg hijklmop".  I have the following regular expression pulling metadata out of the name:

B(\d\d\d\d)    returns 1234

B\d\d\d\d\s*(.*)   returns abcderfg hijklmop     Metadata field called Description

This is working, but I have come across a situation where the file name is longer than the description field will allow.  I don't want to change the length of the field for Laserfiche.  Can I have the regular expression shorten the description?
