it couldn't find anything I had in common with other wallet.dat files....
You couldn't find that wallets are all Berkeley Database files?
$ file foo
foo: Berkeley DB (Btree, version 9, native byte-order)
And that's just doing it manually. Keep in mind that most digital forensics software not only allows searching for specific types of files this way, but also automatic highlighting of files whose contents don't match the extension. You're not fooling anybody.
Yea, but he is not trying to hide it from some secret agency with specialized digital forensic software. The basic script kiddie will not go through all that trouble to find it. Just use a popular compression software with the abbility to encrypt & split the compressed file and then store the split file in different locations. < even on different devices > That should stop the average script kiddie from gaining access to your valueble files. ^smile^
