The 4400 treats the Compact Flash card like a hard disk storing files in DOS format.
Guidelines on
file data transfer
For successful card data transfer, keep the following points in mind:
• 4400 supports a maximum DOS directory size of 128MB. Minimum required
Compact Flash data card size is 32MB.
• Compact Flash cards allow users to store multiple files in one card. The Site name
will be used as the filename for record files (i.e. if the site name is PowerGuide Site,
the filename will be PowerGuide Site00.DDB). A number is automatically appended
to the name such that filenames are automatically incremented every time the user
starts monitoring with that same filename.
• 4400 does not support file fragmentation. When creating a file, it will take the largest
contiguous block and use that size block for data storage. Deleting files from the
memory card is NOT RECOMMENDED. When there is no more space available to
begin new data storage, reformat the card using the 4400, after transferring data files
to a computer.
