Can I delete cups files which too large?

[maxemilian]

The disk manager warned me 0 mb disk space left at root directory. I glanced to root / directory cups takes almost 50GB filesize.

lsblk

    sda      8:0    0 465,8G  0 disk 
    ├─sda1   8:1    0   302M  0 part /boot/efi

You can delete all these files:

access_log
access_log.1
access_log.2
access_log.3
access_log.4
error_log
error_log.1
error_log.2
error_log.3
error_log.4
error_log.O

Have a look into this folder in future and study the log content, seems to be a bit too much data for an error log file IMHO.

I am deleting these files, I hope my system keep stable…

[Wollie]

They are only log files, don’t worry.

But you should find out why they have grown that big…

Thank you for your immediate help.
Yeah, interesting I print a lot of doc for few years and added a few printer 500 times especially damn Canon which not support Linux properly.

By the way , I deletted and restarted system, It’s looks so good!
