Query
:MMEMory:CATalog? [<directory_name>]
Description
Query disk usage information (drive capacity, free space available) and
obtain a list of files and directories in a specified directory in the following
format:
<numeric_value>,<numeric_value>,{<file_entry>}
The command returns two numeric parameters and as many strings as
there are files and directories. The first parameter indicates the total
amount of storage currently used in bytes. The second parameter indicates
the total amount of storage available, also in bytes. The <file_entry> is
a string. Each <file_entry> indicates the name, type, and size of one
file in the directory list:
<file_name>,<file_type>,<file_size>
As the Windows file system has an extension that indicates file type,
<file_type> is always empty. <file_size> provides the size of the
file in bytes. In case of directories, <file_entry> is surrounded by
square brackets and both <file_type> and <file_size> are empty.
