Note：
When a scanned image is being saved to your flash disk, the
File Format LED will be blinking until the scanned image is
successfully saved to your flash disk.
When the scan is completed, the scanner will automatically
create a folder with its subfolder titled “DCIM\PHOTO” on
your flash disk, which will hold the first 9999 scans. Then
“DCIM\PHOTO2” folder will be created for the next 9999
scans, and so on.
Each scanned image is given a file name with the prefix IMG
followed by a 4- digit sequential number in the order the
images are stored. For example, IMG0001.jpg, IMG0002.jpg,
etc.
