NOTES
1. Memory is allocated for a file statically when you set up your files
and will not change unless you re-organize files.
2. The meter automatically performs de-fragmentation of the
memory each time you re-organize your files. This prevents
possible leakage of memory caused by fragmentation. It may
take a couple of seconds.
For more information on configuring specific files, see the following
sections.
The following table can help you calculate an estimated file size when
planning your memory allocation.
