Hey everyone, sorry I have been away for a while, been busy with school and all, but...

I recently looks at an old batch file I created for a YouTube video to register a OCX for the system (MSCOMCTL.OCX)
Well my code is efficient, but I would like to make it more.. Well I have a function (Already) to check if the file exists on the System32
directory and if it finds this file (That OCX ) I want it to check if it is the original file and not corrupted or anything.. So therefore I would
need to compare the found file's CRC-32 Checksum to the original file.

Does anyone have an idea of a function that can do this without using any 3rd EXE party app? Just native batch please .

I have done crc32 check. But there is also md5 in this forum. try search.

Which would be better to use, the crc32 or md5 algorithm?

Md5 is better. But read the initial posts of this discussion for better info.

Well then shouldn't I rather go with CRC-32 instead MD5, because I am looking to just compare a file to a hash.

I have finished my work. You can find code in this post
