Hello,
I have already setted up a button and everything, i just need to know how to setup a code for it to check between two folders..
that when i just click the button, it will access the folders without showing and compare them.
when its done, i need the files that werent found in Folder1 to be deleted in Folder2, but before deleting them I need it to save every files name before it deletes so it can be deleted from a ZIP two.

What have you done, except "a button and everything"? What's the problem? Why doing it, by the way? What do you use for ZIP?

Its for a game, install and uninstall mods, its alot of files. but i need it to detect the correct files, install is already done. uninstall isnt, i need it to fatch the zip files(mod) and compare it to a fresh install, if he wont find the right files, it will save in a String or List and wil delete from the modifeded zip, this means working with 3 zips.

You can use System.IO.Directory.GetFiles, please see:

For working with ZIP, you can use #ziplib:

Another option is using SevenZipSharp, a .NET wrapper of the famous 7-Zip:

Both ZIP libraries are open-source.

Thanks SA, but i have a problem. I cant find how to make it check bettwen 2 folders, and if it doesnt find files that are in Folder2 and not in Folder1, so i want them to get a name save(for the ZIP) and then deleted them in Folder2, not just 1 file but some files, without deleting the files that are found

This is just a matter of your logic. One idea is this: create a Dictionary, System.Collections.Generic.Dictionary<string, Match>. For a key, use a string: file name (make it upper case or lower case) without the different (parent) part of directory name. In a dictionary value, use some "Match" structure: found in one location, in another, in both + any relevant information. Populate the dictionary from both directories to be compare. On second run, use only the dictionary: traverse all key-value pairs, and make the decision based on the value.
