How to move DerivedDataCache from C:/
I would like to know, if I can remove or move the folder "DerivedDataCache". It's stored on my SSD (C:\Users\bobmartien\AppData\Local\UnrealEngine\4.4) even if I installed UE4 and my projects on my other Disk. This guy is more than 10Gb.
I found on Hourence that we can move it from C:/ to the project folder by adding these lines in the DefaultEngine.ini
[RocketDerivedDataBackendGraph] MinimumDaysToKeepFile=7 Root=(Type=KeyLength, Length=120, Inner=AsyncPut) AsyncPut=(Type=AsyncPut, Inner=Hierarchy) Hierarchy=(Type=Hierarchical, Inner=Boot, Inner=Pak, Inner=EnginePak, Inner=Local) Boot=(Type=Boot, Filename=”%GAMEDIR%DerivedDataCache/Boot.ddc”, MaxCacheSize=512) Local=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true, UnusedFileAge=34, FoldersToClean=-1, Path=”%GAMEDIR%DerivedDataCache”) Pak=(Type=ReadPak, Filename=”%GAMEDIR%DerivedDataCache/DDC.ddp”) EnginePak=(Type=ReadPak, Filename=”../../../Engine/DerivedDataCache/DDC.ddp”)
So, I tried it. I created a new blank project with the starter map. And added these lines in the DefaultEngine.ini (E:/Myprojectname/Config). I opened the map and now everything is lagging. It's just the starter map.
I did something wrong ? How to move DerivedDataCache from C:/ ? How I can check if it's working ?
Here is a post regarding the same issue: https://answers.unrealengine.com/questions/8585/deriveddatacache-3-gb-on-c.html
Specifically, the response by ChA1NsAw shows that you may need to add your file path to more places than the one I suggested earlier. Just make sure you change the bold part of his response to match the file path you want to you for your projects.
