What do you mean by Compare? You can easily compare if the files are the same or not.

But to get what is different is more difficult.

vimala,

I will assume you have compared the file sizes to begin with. :nuke:

If all you want to know is whether the 2 files are identical, then get use _Crypt_HashFile to get their hashes. If you get the same result from both files then they are indeed identical. :x

If the hashes are not the same then the 2 files are different, but you have no way of knowing in what way. It could be as little as a single altered byte or large as a completely different content - the only way to find out is to open them and compare their content. :shifty:

How you would do this depends on the size of the files - short files can be read directly into simple variables, longer files (over about 100kb) will need to be read in blocks.

I hope this helps. :P
