Super-fast built-in Search function: you can search for contents and/or entry names
through an archive - no need to extract the archive yourself and to try
a search with some file explorer.
NB: during the search,
files are not even extracted to temp files; all happens quickly in memory!
Fast archive Updater: changes only new, modified files.
Archive Recompression, for reducing further the size of archives.
This is useful for squeezing savegames or database backups, or
for sending large data by e-mail.
