Some time ago I save my wallet to somewhere, not sure where or if it has been overwritten, deleted, destroyed. So recently bought a new external hardrive and
recovered all the files, from all of the possible places the wallet could have been stored, so from usb sticks, memory cards, old drives etc. The wallet was zipped or placed in a rar file, I think.

So  I now have 2 terrabytes of data, that i need to scan for a peice of hex code that will most likely be present in the file.

Where and how do i do this, I have a mac and a pile of data. none of the recovered zipped files have recognisable names, and there are thousands of them, so would prefer to do a complete scan of the data.

Help!
