Skipping files during a "Save Set" recovery

Good day,

We are using networker 8.1.

We are currently running a save set recovery and applying an incremental backup. During the restore, we want to avoid overwriting a large outlook PST file which makes the restore rather long and we are able to retrieve PST files locally on the users PCs therefor we don't really need it. Since there is no option that I am aware of that allows me to exclude a file or directory from the save set recovery, we chose to be prompted for each file and chose not to overwrite this perticular file. However when I chose the option to discard the restore file and not overwrite the current file, the networker client locks up for a really long time. Currently, it's been locked up for over an hour since I've skipped a 3.7 gig pst file. What is happening when I chose to skip a file, why is there such a long delay? On a previous restore, we skipped a 63 MB PST file and it took almost 20 minutes for the system to respond again. Seem to me that skipping or overwriting the file will take the same amount of time, is that correct?

Thanks in advance to whomever takes the time to read this and help out
