A while ago I asked this on G+:
I’ve a VM with many Delphi versions and want to clean up space from %ProgramData% to install more. I think somewhere in the comments it was mentioned what to delete from %ProgramData% to lessen the disk space used by Delphi installations. […]
The VM is on an SSD, and the GUID directories there total to about 50 gigabytes.So any reminder what I can delete there would be much appreciated (:
Besides saving disk space, another advantage is that you get far less duplicates when indexing your filesystem with Everything: the directories contain copies of all files also present in the final installation (like %ProgramFiles%, etc).
Thanks to Ilya S, below are my notes for cleaning up a machine that has Delphi 2007 and Delphi 2010-XE6 installed.
In these folders, backup delete all subdirectories but the directory OFFLINE. Don’t delete files. Keep the backups in case you need them.
