Z4 Library

The Z4 is filesystem-based storage library. Simply using the higher level class Z4::Archive, you can easily store many files within directory tree in one single file and archieve moderate compression.

Advantages are that the read/write access time to Z4 archives is almost constant and all compression and disk write access is suppressed as much as possible by double-level access caching.
The Z4 archive purpose is not common data transfer but packed data storage for smaller and medium database applications.

Here is available package with source codes, basic documentation and example project in Dev-C++.

Z4 is available for free even for commercial use.
But if you want to support development of Z4, contact me.
