Jens,

Data1 of user1 isn't alway's changed. So in the logon this data will be taken from te server and put localy on a client. But when user1 stops, it doens't mean that data1, or part of data1 has been changed. And to avoid useless networktraffic I thought to delete not changed data1 from local hd and copy changed data1 towards server. So data1 that isn't changed just delete. We are talking about several games, and the user is free to play what he wants. When the user has saved games of (example) warcraft3 but not of gta3 then the data of warcraft3 has to go on the server and the data of GTA3 has to be deleted from the local client. Therefor I need to check data's on the files. Sorta if then , else. IF data is newer then old data THEN copy to server ELSE delete data. That kinda syntax is needed :-)
