DE 8.5 System Configuration is quite a bit different to 6.53

Apart from the obsolete locking strategy settings the "Temporary files" folder setting is not in 8.5

With 6.53 the temp folder is important for RDS multi-user setup to be unique for each user workstation

How is this handled in 8.5?

In de85 onwards the default temp catalogue for DataEase files is .\TEMP 

But this can be overridden by 
SET TEMP=

Thank you
