performs de-fragmentation of the memory each time you re-organize your
files. This helps keep all free memory in one continuous block and thus
prevents possible leakage of memory caused by fragmentation.
To change the file properties or to allocate the memory for a new file, double
click on the file partition you want to change, select desired parameters for
your log, and then click OK. For your reference, the record size and the
number of records available for your file are reported in the dialog box.
To delete an existing file partition, click on Delete and then click OK.
The following table shows how to calculate a file size for different log files.
File Record Size, Bytes File Size, Bytes
Event Log 16 Record size x Number of records
Data Log 8 + 4 x Number of parameters Record size x Number of records
TOU Profile Data Log
