With the 4.3.2 patch we’ll be testing some new file optimization tech. As you may be aware, with previous major expansion patches (2.0, 3.0, 4.0, etc.) we’ve carried out a time-consuming process to reorganize the game files currently installed on your hard drive to integrate all previous patch files, essentially ‘cleaning up’ what’s on your computer and reducing the full installation size. This process used to require an amount of free hard drive space double that of the entire installation size to complete, which is why we’ve reserved them for large expansion-sized patches.
The new tech we’re testing with the 4.3.2 PTR will process these cleanups with no additional hard drive space required beyond what the patch is adding. Because of that you may see them appear more frequently with patches.
While the cleanup is occurring you’ll see a specific message on the launcher informing you the process is currently taking place. If you encounter any issues with the new process please be sure to visit our support site at
