If some have noticed a good chunk of HDD space missing its because of this folder:
This is a cache for your assets or so it seems from reading places. My problem was the fact that this was eating away at my poor little 120 GB SSD, atleast 7 GB of data.
So for those that want an easy way to move this folder you can just make a symbolic link with the following:
mklink /d “C:\ProgramData\Epic\Engine\DerivedDataCache” “D:\U4_Temp\DerivedDataCache”
The first directory is UE4s normal directory path for this cache. “C:\ProgramData\Epic\Engine\DerivedDataCache”
The second is where I want to create the physical link to. “D:\U4_Temp\DerivedDataCache”
Please note i created D:\U4_Temp manually.
All you have to do is rename your DerivedDataCache to xDerivedDataCache and run the above command in CMD or in a bat file to create the link. Not that I deleted my cache folder so i had to wait about 5 minutes for UE4 to recreate the files on my D drive.
Hope this helps…
And remember its not the size of the HDD its how you use it!
