File Management
File Extension Designation
File extensions are used to indicate the type of file. The list
below provides a description of all types of file extensions
used by LectroCount DMS i1000. Care should be taken
not to delete any files that are critical to the LectroCount
DMS i1000 operation or for making deliveries.
For example, the “
.SLF” files contain information such
as the customer data base, the logon data base,
configuration files, ticket configuration files, application
information, and others. These “ .SLF” files are typically
created by the office software and can be reinstalled on
the DMS i1000 Module internal flash memory using the
USB flash memory device.
NOTE: Files with extensions “.BAT”, “.COM”, “.EXE”,
“ .LNG”, and “.SYS” are critical to LectroCount DMS i1000
operation. Deletion of any files with these extensions
could lead to complete system failure. These files are
not created or configured by the office program, they are
resident on the DMS i1000 Module internal flash memory.
To create a backup of the LectroCount DMS i1000 Module
internal flash memory, follow the instructions for “ Create
DMS i1000 Image” on page 15.
*SLF is “Skip List File”.
