Some systems use hard links where one file appears in multiple places but only occupies space once. Most archive formats do not support this and will save each link as a separate, full-sized file, ballooning the archive's size. When dealing with large archives or extensive file

It is possible for a compressed archive to be larger than its original folder due to several technical factors:

Files that are already highly compressed (like .jpg images, .mp4 videos, or .exe executable images) often cannot be compressed further. Attempting to compress them again may only add overhead.
