Hi Alex,
It sounds like you can strip out the null characters and get the text back.

Subject: null chars in text file: recover text?

Hi all,
Someone on another list sent me a text file, saying that much of the text is
gone but the file size is still the same. This file has been periodically
overwritten (a new copy written over the old one as the file was backed up),
and one day the file's text ended at a random spot and all text after that
spot was erased. I looked at the file in a perl script that gave me the
first character that was not ascii 0 (what I think is a null character) and
the first characters that were not null were the end of the text in the
file, not surprisingly. This tells me that all text after some point was,
for some reason, replaced by null characters. Is there any hope of
recovering the text now? I hope this made sense.


Have a great day,
Alex
