This unzip package allow extract file from .ZIP file, compatible with PKZip 2.04g
WinZip, InfoZip tools and compatible.
- Encryption and multi volume ZipFile (span) are not supported.
+
+ Multi volume ZipFile (span) are not supported.
+ Encryption compatible with pkzip 2.04g only supported
Old compressions used by old PKZip 1.x are not supported
- THIS IS AN ALPHA VERSION. AT THIS STAGE OF DEVELOPPEMENT, SOMES API OR STRUCTURE
- CAN CHANGE IN FUTURE VERSION !!
