As your configuration grows, you may find it necessary to
compress or expand your configuration file.
Configuration files initially contain 2,048 32-byte records.
As you configure items in a file, records are used sequentially
from the beginning of the file. As the file size increases, the
number of free records at the end of the file decreases.
If you delete items from a configuration file, the records
are not immediately recovered, so the middle of your file may contain
some unused records. Unused records in the middle of the file are
not reflected in the number of free records count and are not available
for reuse. By compressing the file, you cause all data to be stored
in a contiguous block of records and all unused records to be located
at the end of the file. Thus, compressing a file enables you to
determine the actual number of free records in a file before adding
or deleting records.
To compress a file, enter a 0 in the Number of Additional
Records field and press [Compress File]
You can also use this function to add records to the file
or to delete unused records from the file. To do so, enter a number
in the Number of Additional Records field. A positive number causes
records to be added (up to the file size limit of 65,535 records).
A negative number causes that number of free records to be deleted
from the file. After you have entered the number of records to be
added or deleted, press the [Compress File] key.
When you press [Compress File], NMMGR begins
compressing the file immediately. The terminal is locked to indicate
that NMMGR is not available until finished. When the compression
is completed, NMMGR prints the following message in the message
field:
Configuration file compressed.

 | NOTE: Compress time depends on the number of entries in the
file. For a file that contains a small amount of data, compression
usually takes fewer than 30 seconds. However, compressing a file
that contains a lot of data can take several minutes. |

Enter the number of records that you want to add
to the file (positive integer) or the number of unused records that
