Andi - I completely discard them as hidden or other files. Because what I did was move the hplip folder to free up space, and that the ini error, was saved correctly. Then I did the backup, and restore.
Neil - What you propose I do not think that alone is the problem. Among other things because I have another computer with two bootable partitions of 30gb without that problem.
On the pc with problems, I leave it on day and night on, for backups. And this affects the Samba client, forcing me to restart it every day. Also the memory does not recognize it correctly, with 4gb, and the virtualaddress in 3072mb, shows me approx. 3500mb. Or a combination of several things.
