McFile is an application that allows one to perform operations on files contained on either a PalmOS device or on memory cards used with the device.
Aside from basic functions such as copying files and moving files, by reating associations with other applications, viewing of text or DOC files, creating mail attachments, etc. is possible.

-File Operations
Basic operations such as copying, moving and erasing files on a memory card are possible.
As with file managers used on a PC, one can select folders as well, so erasing unnecessary folders trees etc., is easily possible.

-Beaming
Aside from the usual sending and receiving databases and files using the infrared port, it is possible to work with files contained within the memory card as well.
Beaming of files on the memory card is not restricted to any particular file types, so files other than prc/pdb types can be used as well.

-Application Associations
By creating associations with applications that contain interfaces for external links, it is possible to "Open" or "Send" a file.
"Text Viewer" and "Mail Attach" settings are included as examples.

-Jog Compatibility
McFile is compatible with the Jog Dial / Jog Wheel installed in various model.
It is possible to do file operations with the file list as well as work with popup menus using only the Jog function.
Furthermore, by using PowerJOG (by Yamada Tatsushi) with a CLIE, it is possible to do almost everything with only the Jog function.
