Also performance is gonna suck if you want to extract file by file instead of the whole thing if you use that method though.
Thank you so much for watching. However, Windows Explorer itself extracts files from archives with the automatic setting of file attributes. Windows does it somehow... I wish we could do that...

After all, a real full-fledged file extraction procedure includes the mandatory setting of the date, time, and file attributes. Otherwise, it's not a full-fledged unpacking.
