File comparison to check for exact match ?

[MoiMeme]

Hi,

I am looking for a software that would allow to check if files that I copy
for critical backup use are strictly equal to the source files.

How can I do that ?

Why don't you just use a backup program, such as Backup MYPC. You can choose
to verify the backup automatically after it is has been completed. A popup
window will tell you if everything was copied correctly or if there were
errors.

Open a console window (also known as "DOS box") and type "fc /?".

Hi,

I suggest you look into Microsoft's Robocopy.exe. As far as I remember,
as default, it will not re-copy a file if it have the same time stamp
and size.

Robocopy.exe is available here:

Windows Server 2003 Resource Kit Tools
http://www.microsoft.com/downloads/...69-57ff-4ae7-96ee-b18c4790cffd&DisplayLang=en

(The kit will install on WinXP or later and you can copy only
needed files to other computers)

See rktools.chm and robocopy.doc for documentation for Robocopy.exe.

I have a sync sofware but look for a way to check copied file is identical
to source one

Hi,

Microsoft's Windiff.exe is an option.

It is to be found on a Win2k/WinXP CD, in the Support Tools

Install "Support Tools" by starting suptools.msi from
<cd-drive>\Support\Tools\

Also note that there is updated versions of Support Tools available:

Windows XP Service Pack 2 Support Tools
http://www.microsoft.com/downloads/details.aspx?FamilyID=49ae8576-9bb9-4126-9761-ba8011fabf38

After the install, you will find Windiff.exe in
%ProgramFiles%\Support Tools\
