| 6 | This unzip package allow creates .ZIP file, compatible with PKZip 2.04g | |
| 7 | WinZip, InfoZip tools and compatible. | |
| 8 | Multi volume ZipFile (span) are not supported. | |
| 9 | Encryption compatible with pkzip 2.04g only supported | |
| 10 | Old compressions used by old PKZip 1.x are not supported | |
| 11 | ||
| 12 | For uncompress .zip file, look at unzip.h | |
