 +===== TAR archive mounting =====
 +If you work with data consisting of many small files, you **should** store them in tar archives to save inodes. There is a way to mount a tar archive to a specific directory in the simmilar way you mount ISO image. You can use the following wrapper script to //mount// ARCHIVE to DIRECTORY:
 +
 +  /opt/bin/tarmount -a ARCHIVE DIRECTORY
 +
 +and //umount// when you finish your work:
 +
 +  /opt/bin/tarmount DIRECTORY
 +
 +You can also use the original tool called [[https://github.com/mxmlnkn/ratarmount | ratarmount]] directly through the link:
 +
 +  /opt/bin/tarmounter
