In
computing, ftype
is a
command-line utility on
Microsoft Windows that is used to display or change the link between a
file type and an
executable program.
[1]
The ftype
command was introduced as a
shell builtin to
cmd.exe with the release of
Windows NT 4.0. It lists all
Registry keys in
HKEY CLASSES ROOT which contain the shell\open\command subkey, and prints out the
REG SZ contents of the (default) value within these keys. Since it is an internal command built into cmd.exe
, there is no FTYPE.EXE
.
Because (default) values in HKEY_CLASSES_ROOT\<keyname>\shell\open\command contain information on how to open file types with registered extensions, this command essentially lists all registered file types, and which executables are used to open them, along with any switches used by the executable. [2]
Multiple file extensions can be associated with the same file type and several file types can be linked to the same executable application. [3]
