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.
