Is there software that can compare two folders and files inside it using checksums?

If you're gonna be reading both sides anyway, there's no point in computing the checksum.
FreeFileSync has a "File Content" mode that compares every file bit by bit.
Set it to that, and hit compare. If both sides are exactly the same, it'll say there are no files to synchronize.

Why? Don't they achieve same thing?

Yes, and that's exactly why there's no point in doing the extra work.

Maybe a little bit paranoia (￣ω￣) . But thanks for FreeFileSync advice. I keep digging similar software, atleaast no i have two reference points

Beyond Compare might help you. I've been using a cracked version forever. For some reason I like it's ui.

Make a torrent of one directory, no trackers or anything.
Add the torrent to your client and set the location to the other directory.
If it reaches 100%, the files and directories are the same. If it errors, something's different. If there's extra files in the directory it won't mind, but you can easily check that yourself.

Also be careful when removing the torrent from your client, make sure "delete contents" is unchecked.

I asked ChatGPT to do that, and its solution seems to be in order.
Copy and paste this script into a powershell window: https://pastebin.com/C58UVhkJ
Then, assuming that the folders you want to compare are "C:\Path\To\Folder1" and "C:\Other\Folder2", type:
Compare-FoldersByHash -folder1 "C:\Path\To\Folder1" -folder2 "C:\Other\Folder2"

From what i tested so far. I can create Checksum file for folder (Via OpenHashTab or after copying via TeraCopy) . And later check it by just clicking it. It works fine, however. It needs file's location. If i move folder anywhere else, it wont see it

However, if i do it inside folder. It works just fine if folder is moved somewhere else. HashMyFiles as well works properly.

Tested this. I rather make one that would use cmd or python instead of powershell

Torrent uses SHA1 for checksums?

The goal is to save time in comparing the entire folder. Computing the checksums for both files uses the most time because both files need to be processed completely. The other methods first perform a triage and if the files are different, it flags that and moves on. If they are similar, it then compares bits and as soon as it finds something different, it stops processing, flags the files as being different, and moves on. No need to process the remainder of the file.

v1 torrents use SHA1, v2 use SHA256
But it's not as straightforward as hashing a whole file for one checksum, as I understand it several pieces of the file are hashed with many checksums. It's complex and I don't fully understand it myself so you'd have to look it up.
