Hi Eric
Are you are talking about backing up Ideas Genie Pro here?
If yes, and the folder name is the same, then you will overwrite the previous backup, so deleting is unnecessary.
You could try running the PACK program.
Under the System tab, program is Pack Files - GA202
However,its always a good idea to do a Backup before running Pack, so you are in a catch-22.
The PACK program can reduce the size of IG Pro files by freeing up the space occupied by deleted records.
(When you delete records in IG Pro, they are marked for deletion only, pending that PACK operation.
They can not be seen any more as you use the programs of course.)
How big is the drive you are backing up to?
