Description
This command retrieves the File Name of the
received Item Number inside the current
directory path. This command is designed to
work in conjunction with the “List Files”
command.
By using the “List Files” command combined
with this “Get File Item Name” command,
the user can have a detailed list with names
of all the directories inside the current
selected/working directory path.
*The Item Number parameter in this
command must always be less than the
previously found number of files with the “List
Files” command. As an example: when the
“List Files” command is called, and it returns
10 files, then the “Get File Item Name” could
only ask for the file name of the items 0 to 9.
