Hi again Don,
Comparing files really isnt hard at all.
Since the bytes can be different however, all the bytes must be
compared. This is especially important when comparing files
on the hard drive to files on a recorded CD or DVD disk because
those files could be corrupt by only 1 single byte and that
could screw up the system reading of the entire file. I've
actually had this happen a few times, so that's why this program
came about.
The program makes a list of all the files to be checked, then
goes through them one by one checking each and every byte.
If there is even one byte that is not the same or if one
file has even one single byte less than the other an error
gets written to the Report.txt file that says what the file
name is and it's location.
Just a few weeks ago while i was trying out some new brand CD's
(that i never used before) i had some 6000 files record just
perfectly on CD, while 3 had corrupt bytes. I found that
out later, but what happened was i went to copy the files on CD
back to the hard drive and i got an error when the system copy
got to one file that would not copy and took a real long time
to provide the error message "could not read from disk" or
something like that. At that point, the system copy stopped
altogether so any files that were not copied up to that point
were simply not copied either, even though those files were ok.
I eventually got the stuff copied, but after it finally went
through all the files there were 3 files that were corrupt.
Luckily i wasnt depending on that data for anything important
as i still had the hard drive copies.
Now, i verify every file that gets recorded either using this
program or Nero verify. (Oh yeah another reason for this program
is that the old Nero 'verify' i had would cause an exception
if there were too many files in one directory. Ahead made an update
now though, but it's no big deal at this point and i pretty much
like using my own programs better anyway).
The code i will send you has been checked to make sure all the
includes get included in the zip. It's basically DOS oriented
though, but it's still easy to use. I was thinking of doing
a windows interface too btw. That would be neat. For now,
the directory and two drive letters get inserted into lines
in the Eu program source file. Since the program can look
down into sub dirs it only takes a few seconds to use anyway.
Take care,
Al
E boa sorte com sua programacao Euphoria!
