Data is logged automatically and based on the Logging Method (Circular or Segmented Log), when the log is full it goes back to the beginning ans start overwriting the old data. Even if you change the attributes of a file to Read Only. A user who wants to modify the data will change it to Read/Write. You should be able to use a script, open each file, and change the attributes to Read Only. Regards, Behnam www.winccflexiblemastery.com
