Installation-file-cleaning is currently only available in the licensed edition of Chocolatey ($96 a year) and the developers seemingly have no plans to offer cache-cleaning support for the free version.
The package installation files can easily take gigabytes of storage space and to my knowledge they only increase in size as the user updates packages and installs new software, with only your hard drive capacity as the upper limit.
I don't know if Chocolatey stores cache in one central location — something is saved to ~\AppData\Local\Temp
but the majority is located in the lib
* folders in ~\ProgramData\chocolatey
. Also the log files in the logs
folder total to over 100 MB on my system. Is there any way to fully clear Chocolatey cache without manually deleting directories?
