Monitor of memory buffers for better estimation of copying time

99% is pleasing only for the first hour.

Copymon is a monitor of memory buffers for better estimation of copying time.

It shows the most probable estimated time of copying files by monitoring Dirty-Writeback Memory stream. It estimates the time until all the buffers are REALLY written to the disk - as opposed to most of the file managers which are showing the estimated time to writing to a buffer only.

Enter copymon to start monitoring:

It observes /proc/meminfo which allows to determine ETA more precisely:
