ShuffleDepth in DiskProfile controls how files are selected:
-1 = no shuffle (preserve source order)
0 = all files in random order
N = group files by folder at depth N from /media, shuffle groups,
copy entire group before moving to next
Exposed in disk profile UI as a select with level descriptions.
