Is there a utility that will allow me to compare two files to verify they are actually the same?

[Ronstang]

I have concerns that although two video files report as being the same and having the same number of bytes that one might be corrupt. I need a utility that can compare two files bit for bit and verify that they are in fact the same.....I can use EAC to compare two wav files ....but I need something that compares two of any type of files.....

You can compare the md5 sums of each video.

That helps....considering I have no idea what you are talking about.

Thanks......HAHAHA

Your loss I guess.

EDIT: Follow these instructions.

lol n0c!

Just doing a search for MD5 on google... there's even a nice Windows GUI MD5 program out there.

I followed up with a link

I would have just written a small program to do that.....it'll take less than 5 mins in any modern language

Or written a unix script

Btw, what is MD5?

Its a cryptographic one way hash.

I still have my old Norton Utilities for DOS, so I use FC.EXE (File Compare). You still have real DOS if you run Win98 or ME. I don't know if it works under the DOS emulation in NT/2K. I don't even know if there is a DOS emulation in XP, but since I won't be buying it for the next few years, I really don't care.

Thanks....I will give this a try.

Win2k (and I assume WinXP) have FC already.

 

[everman]

In win xp ( I'm not sure if this is in 2k ), on the command line type fc /a pathOfFile1.file.ext pathOfFile2.file.ext

and if anything turned up (those are any differences) then you'd know.

Remember to use the /B switch if the two files are binary (and I assume they are since they are video). E.g.:

FC /B c:\file1.avi d:\file1.avi

Oops! Right you are. So does DOS 7 (Win 98). I forgot that I deleted that from my old Norton for DOS when M$ finally added it.

They keep doing that. MS-DOS 6.22 was the best DOS they ever produced because they finally got almost everything they stole from DR-DOS right.
