Alternatively, have a squiz at the file with Vern Buerg's LIST
which will happily read any sort of file, displaying any readable text
and using symbols for non-text characters (and you can toggle a HEX
view ON/OFF if you're fluent in hex ;-).
Even the older (freeware?) versions listed under the "Utilities" link
at the bottom of that page should be able to do the trick. The two
newer versions are Shareware and Demoware, but I doubt that you will
need the latter 30-day demo of List Enhanced (unless your file is
bigger than 16MB :).
Mind you, LIST is typical bloatware at a full 26KB and runs in a DOS
window under most (all?) versions of Windows, so may not suit you. ;-)
