Windows 7: Extracting RAR archives results in different extracted file sizes

Windows, you can't exceed MAX_PATH value (259 characters for files, 248 for folders)

Okay so I tested this using a different archive (because it's the smallest one and took a lot less time to extract) from the same drive with the other archives stored and extracted them to the other drive I'm using. I've attached screenshots showing the sizes of each extracted folder from both my Windows laptop and Mac. It's bizarre to me to see but I extracted the same archive using the 3 different programs (Bandizip, 7Zip, WinRAR) and got different results from each. What does anyone make of this? The 4th properties/info pane is of the same archive that I extracted a few days ago with WinRAR and as you can see it even shows a different size than the WinRAR extraction I did last night.

Also as you can see the size of each is the same when viewing info pane on Mac but like before each folder shows a different size and file/folder count when viewing properties on Windows.

I am curious, once extracted, do the (contents) function properly?

You are comparing to files on two different Operating Systems, if you check the files on the same system, open with the same program, they should be the same, the hashes should be identical

Yes, everything so far seems to view and function properly that is within the folders.

Yes that's my issue...take macOS out of the equation. When comparing the folders extracted they are different file sizes in Windows. This has occurred when extracting the same archive twice with WinRAR and they are different sizes. Also when I extracted the same archive via 3 different unarchivers as you can see in the last post, they are all three different sizes.

In 7Zip it should calculate a CRC for each file. You can use the program HashCalc and compare that CRC32 and see if the files match up.

cgh98,
You are playing games with the compression algorithms.
Any time you compress data, you are utilizing a compression algorithm. 7zip, WinRar, WinZip, PeaZip, etc., they all utilize their own proprietary algorithm.

Why is this so important?

I mean honestly I'm just concerned that all the files that were originally archived aren't going to be there. Still no reason I can find as to why extracting the same archive using the same program (WinRAR) and extracting it to the same drive; produces different results/different sizes.

The same zipped archive
you extract it to say the desktop?
then you extract it to the desktop again?
and compare them right?
and they are different right?
how are you comparing them?
both there extracted, at the same time? right?

Yes that's exactly how I'm comparing them. In some of the folders extracted they have both been the same file size but then some folders extracted have been different. When having extracted them like you said, using the same program to the same location.

Like in the first screenshot I posted showing 3 properties windows of the folder all 3 called "All Flash Drives & SD Cards" I extracted all 3 from the same original archive and the second and third ones ended up being the same size but they are different from when I extracted it the first time.
