Where is the /Temp folder reported in the Output Log stored on disk?
Given log entries like these when playing in editor:
LogPlayLevel: Creating play world package: /Temp/UEDPIE_0_Untitled_1
LogPlayLevel: PIE: Created PIE world by copying editor world from /Temp/Untitled_1.Untitled_1 to /Temp/UEDPIE_0_Untitled_1.Untitled_1 (0.001756s)
Is /Temp just a logical path in memory, or does it physically exist on disk while the play in editor session is active?
