How to find all files that consist only of null bytes (any number of them)

Solution 1:

Install the (free) version of TotalCommander and search for all files containing 0x0 ten times for example. Then look in the files what they really contain.

Solution 2:

I had the very same problem. I wonder that the RegEx in TotalCommander worked for SWilk, as TC does not support \0 in RegEx search according to their own support forum: http://www.ghisler.ch/board/viewtopic.php?t=26512 (and it did not work for me).

I ended up using grepWin: http://stefanstools.sourceforge.net/grepWin.html

Use "RegEx Search", Search Pattern "\A\0+\Z" and make sure to check the limits (default is not include binaries and files larger than 2000 KB)
