This might have been asked but I have a project where I take two file locations
Location A is a subset of Location B so I have to take away locations A files.
There are two ways to accomplish this. One i suse the file iterate and check to see if location "b"'s file exisit in location "a". If it does not exisit then I can copy it to location C from my build process. This i use the Path manupulation to strip the path of and name off so when I copy the file to location C I can maintain the additional paths that are used with the files. I use Robocopy to perform the copy after geting the path taken away.
Example
Location A - \\ServerLoc\Share\MainData\\*.\* - Recursive from here
Location B - \\ServerLoc\Share\SecondaryData\\*.\* - Recursive from here
Location C - Localdrive\path\..\file startlocation
So when I end up I get Location "C" with the recursive path to the files that only reside in Location B. This is taking a very long time to run checking over 3000 files.
The other option is copy Location B down to location C then stip away the files that location has in location C. This is very quick but leaves behind a massive amount of empty directories. I can write vbscript code to remove empty directories and empty subdirectories with file count of 0 and subfolder count of 0. But I was looking how do I do this with the internal functions within finalbuilder?

I found a work around that works.
Copy location A down to location C temp location.
Take the files iterate from location B and string replace it with location C root path.
Then delete the files if they exist. - "This takes the longest time."
I do a FileSet Derfine to location C getttng all the files.
Move the fileset to the real location of C.
Delete the temp location.
This all take about 9 minutes to work. The other way I stated with uising iterates from file A to B and only copying the difference to location C took too long to execute.

Hi Dennis,
I’m glad you found a workaround. I have some ideas for actions which should make this kind of thing easy to do, so I’ve added them to the to-do list… but we’re pretty busy, so it may be a while before they see the light of day. :-).
Regards,
Angus

The work around is okay but my scripted project took less time 15 minutes to using finalbuilder is now to 45 minutes! I will see if I can find another solution with the check file after the influx of items here have settled down.
