The e2compr package consists of a set of patches and utilities written primarily by Antoine Dumesnil de Maricourt ( to provide transparent compression and decompression in the second extended (ext2) filesystem.

Antoine passed maintainership to Peter Moulder ( when Peter requested permission to distribute an e2compr patch updated for the then-new Linux-2.0.0.

Since then, Peter, Jan Rêkorajski, Gábor J.Tóth ( and Tom Lees ( and others have developed and maintained e2compr.

In February 2000, Riley Williams rhw@MemAlpha.CX became joint e2compr maintainer with Peter. The address at the bottom of each e2compr web page forwards to both Riley and Peter.

Antoine no longer has the time to maintain e2compr; communication should probably be sent to e2compr maintainers or to the e2compr mailing list. (See below for how to subscribe to the lists).

Current state of project

The system is already usable now, and has been since at least 1997. Many people already rely on it.

Nevertheless, there are many avenues for improvement.

Error detection and handling could be improved, which is an issue for those with unreliable hard drive I/O.

See the TODO file in the distribution for a longer list of possibilities for further development (i.e. `wishlist').

I wouldn't use e2compr on a ``production'' machine (where neither faults nor delays are tolerated).
