Hi all,

My app Windows forms .NET in Win XP copy files pdfs in shared network folder in a server win 2003.

Admin user in Win2003 detects some corrupt files pdfs, in that shared folder.

I want check if a fileis copied right in shared folder

Andre Krijen says me the best way is to create a MD5Hash of original file. When the file is copied, verify the MD5Hash file of the copied one with the original one.

I have big pdf files.

apply md5 hash about big file, any performance problem ??

If I only check (without generate md5 hash) Length of files (original and copied) ??

Thanks in advanced.
