When i installed tile proxy i nominated my external f 'drive for the cache folders and photoreal world .They are in this drive but i have noticed an exact copy of each are also in my c' drive program files microsoft games,Is this correct? and if not should i delete them from c' drive?Having them appear in two drives does this affect the usage of resouceseverything seems to be working ok with tile proxy.Your advice apprieciatedThanks Don

I would say that if it's working, then leave it alone. You could try moving or renaming the ones on your c drive and put them back if you get problems.IAN
