About 3GB of duplicate files are stored in C:\Users\…\AppData\Local\JetBrains\Installations
Resharper Files are Duplicated multiple times for each Installation, not even using HardLinks or symlinks to minimize the impact. The Diff between each folder is only about 1 Meg, the size it ACTUALLY takes to differentiate the installs. And here they waste 3GB for nothing with not a care in the world and this is a PROGRAMMING SOFTWARE DEVELOPMENT COMPANYThere is currently not a good workaround for this because manually linking the files is too hard and would need to be scripted. But they should handle this themselves.
