TIPS AND TECHNIQUES
Select Only Desired Files For Upload
If you keep reusing the same fob for database
uploads, be sure to either delete all out-of-date or
non-desired files or, take care in selecting/de-
selecting files from the IFD display list. Not doing so
may extend data upload times considerably by
uploading unintended files.
