cmd file to start monitoring 4 folders

[OldCityCat]

I created a cmd file per the instruction in Run As Service.
I added these 4 lines.
"C:\Program Files\FreeFileSync\RealTimeSync.exe" "C:\Users\xxx\Documents\FreeSyncBatchFiles\CPR.ffs_Batch"
"C:\Program Files\FreeFileSync\RealTimeSync.exe" "C:\Users\xxx\Documents\FreeSyncBatchFiles\PSR.ffs_Batch"
"C:\Program Files\FreeFileSync\RealTimeSync.exe" "C:\Users\xxx\Documents\FreeSyncBatchFiles\ResHab.ffs_Batch"
"C:\Program Files\FreeFileSync\RealTimeSync.exe" "C:\Users\xxx\Documents\FreeSyncBatchFiles\MedWaiver.ffs_Batch"

When It runs the first CPR batch starts, then process just hang.
Am I missing something?

Thanks
