? - Find File or Folder
M - Copy From File to Another
This command searches for a specific file or folder name at the specified path. If the
directory exists, ALFAT outputs the file size, attributes and date & time of modification,
otherwise, it returns an error indicating that the file is not found.
* File Attributes are one byte Standard Attribute Structure in FAT system.
Since ALFAT supports opening more than one file at the same time and it supports three
file media, this command comes handy copy data from a file to another, even if the files
are located on different media.
