Guys, be careful with this patch!!!Thank you very much for the reports about issues with space, next RouterOS version will fix the issue.
Meanwhile this package can be used to clear space on your router,
- upload package to your router;
- run /system reboot
It works on every board and does not depend on version.
I uploaded it to a test CCR1016 and it doesn't come up after reboot!
Test it first!
