Note that unlike the zip archives (that really work like folders), bzip2 files cannot be edited.
tar/.tar.gz/.taz/.tgz archives can be opened/extracted, too, and you do not need bzip2lib.prc plugin.
Installation:
Copy bzip2lib.prc to your device RAM. (For example use Hotsync.)
Uninstallation:
Use Explorer to delete bzip2lib from RAM,
(If you delete the whole Explorer from the launcher, the bzip2lib plugin will be deleted as well.)
