UE4 eats a lot of memory?

Question

unreal engine

At the initial stage of installing the engine itself , I specially installed disk D. Since it's on a C drive, space problems.
But, why do I lose memory on the C drive with every action . Especially when I add or save.

- How to make UE4 forget the C drive and everything connected with it, and work only with the D drive ?

Answer 1

In the Epic games launcher, check the path for the storage cache,
In Control Panel, System and Security, System, Advanced System Settings, Advanced, Performance - Options, Performance Options - Advanced - Virtual Memory, check the location and size of the swap file.
Also believe Editor Prefrences - General - Global paths for Data Cache.
Also check (UE_ROOT_DIR)\Engine\Config\BaseEngine.ini section [InstalledDerivedDataBackendGraph]
Line
Local=(Type=FileSystem, ReadOnly=false, Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true, UnusedFileAge=34, FoldersToClean=-1, Path="%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache", EditorOverrideSetting=LocalDerivedDataCache)
Path parameter.
