You could make a simple script that lists "file" output for
all files (just to be sure because of possible suffix renaming)
for further inspection. Sometimes, you can also run "strings"
for a given file - maybe that can be used to identify typical
suspicious string patters for a "strings + grep" combination
so less manual identification has to be done.
