While trying to destroy/wipe single file is there a possibility that disk sectors can be read/written by 3rd party application before it will be wiped? It can be viable in our custom DLP policies...
It is not possible to wipe single file in Disk Wiper - either wipe entire partition (which destroys file system immediately by wiping first partition sectors so nothing can be read/written there) or free space (during this operation, partition is locked and nothing can be read/written there).
