Hello Monks, Sometime ago I have written this code to read a file and look for a file base on a path. Then It would copy the file to another directory and rename it with a number found at begin of line. It works fine however I didn't notice that the file starts coming with duplicate numbers. They have different paths but since I rename the file with begin of line number. It takes the file and renames it the same and doesn't copy to the destination directory. For Example: 
123456|H:\00005199.016
123456|H:\00001598.017

Files get rename to 123456.rtf
and 123456.rtf (They are completly different files)  Unfortunately it 
+takes the content of the previous one which it is a problem.

I haven't used hash, do you have any ideas to have it check to previous numbers in a hash array if it finds a duplicate to rename the duplicate with 123456.rtf, 123456a.rtf and so forth. Any suggestions would be appreciated.
