Hi, im trying to figure out if its possible to make a rule so that folders and all files in the subfolders are placed on the same Hard drive together instead of each file in a folder placed on random hard drives. Ie
 
 
C:\
     Folder 1
     Folder 2
         Folder A
         Folder B
     Folder 3
         Folder C
 
 
In the example above all the files in Folder A will be placed on the same HD(doesn't matter which but all together). Folder B files all on the same HD. etc etc
 
 
Reason for this is if I have a HD failure instead of missing random files from random folders its a lot easier for me to say "ok Folder A is gone and needs to be restored"
