In this mode, you can save internal memory data to an
inserted SD card, or load data from media into internal
memory. You can also copy or delete ﬁles, or format media.
The following media can be used.
The M50 supports MS-DOS FAT16 and FAT32 formats.
FAT 32 supports up to 2 GB.
SDHC memory cards are not supported.
(For SD cards, please see "Types of media you can use" on
page 91 of the Owner's manual)
Files, directories, and icons
The M50 manages data on media in a hierarchical manner,
using ﬁles and directories. The contents of a ﬁle (whether it
is a ﬁle or a directory) are indicated not only by the name,
but also graphically, by an icon. Files and directories have
differently shaped icons.
The M50 collectively refers to ﬁles and directories recogniz-
able by MS-DOS (readable by an MS-DOS computer), as
"DOS ﬁles" and "DOS directories." Different types of DOS
ﬁle are distinguished by the extension added to their ﬁle-
In the case of a DOS ﬁle with an extension other than listed
below, selecting Load selected to access the dialog box will
cause the ﬁle to be considered to be a Standard MIDI File
(SMF). However, you can't load ﬁles that are not in SMF

MIDI Exclusive data
When M50 data is saved, one of these ﬁlename extensions
will be added automatically, according to the type of data. If
these ﬁlename extensions are modiﬁed on a computer, the
ﬁle will be treated as an undeﬁned ﬁle when it is reloaded
back into the M50, and will be handled as a Standard MIDI
Files handled by the M50 have the shown in the structure
(see next page). Since .PCG and .SNG ﬁles can be opened to
divide their contents, they are displayed as directory icons.
