Since we are using TC 8.1.4 and there is known issue with cleaning system messages, I've applied proposed workaround, https://youtrack.jetbrains.com/issue/TW-36830
Total size, decrease from 130GB to 80GB, but I think still there are a plenty of files that could be deleted.
Do you have any suggestion, whether I should simply remove old files (let's say files from 2014), as well.
Is there any dependency or simple deletion will suffice.
Thank you in advance for help.
