You may create your own known file types and add their file
signatures for scanning in Known File Types. They will appear in
their respective folders on the File Types dialog
box.
You can do that either by using the R-Studio's graphic interface or by direct
editing the known file description file specified on the
R-Studio Main
settings dialog box.
The easiest way to add your own is to use the R-Studio's graphic interface.

Additional properties of
the file type. If you want to specify several properties, they
should be separated by a space.
NO_SCAN: Not to
be scanned for. If this flag is used, R-Studio will not search
for such file type. Such files will be shown when sorting files by
their extensions.
TXT_ANSI: The
file can be viewed as ANSI text. If this flag is specified, the
file can be correctly represented as an ANSI text. When previewing,
this file will be immediately sent to Text/hexadecimal editor.
TXT_UNICODE: The
file can be viewed as UNICODE text. If this flag is specified, the
file can be correctly represented as a UNICODE text. When
previewing, this file will be immediately sent to
