Hi George,
I think i have understood your requirement correctly, you want sender file adapter to check if abc.xls file available in DirectoryA, if its available then your script will run to pick all remaining file in DirectoryA and move to DirecotyB for further processing. If that's the case can you check below steps/configuration helpful for your requirement.
1. Configure sender CC to pick abc.xls in DirectoryA
2. Execute script to pick files from *.xls from DirectoryA to DirectoryB (Please note in your script you have to put condition to move files from DirectoryA to DirectoryB only if absolute path %F contains DirectoryA, otherwise skip the process)
3. Use Advanced Selection for Source file in same sender CC to pick *.xls files from DirectoryB
Sender CC:
