Description
Displays or modifies file types used in file extension associations
Syntax
|
FTYPE |
|
[fileType[=[openCommandString]]] |
Parameters and Switches
|
fileType |
|
Specifies the file type
to examine or change |
|
openCommandString |
|
Specifies the open command to use when
launching files of this type. |
Examples, Notes and Instructions
Type FTYPE without parameters to display the current file types that have open command strings defined.
FTYPE is invoked with just a file type, it displays the current open command string for that file type. Specify nothing for the open
command string and the FTYPE command will delete the open command string for the file type.
Within an open command string %0 or %1 are substituted with the file name being launched through the assocation. %* gets all
the parameters and %2 gets the 1st parameter, %4
%3 the second, etc. %~n gets all the remaining parameters starting with the nth parameter, where n may be between 2 and 9, inclusive.
For example:
ASSOC .pl=PerlScript
FTYPE PerlScript=perl.exe %1 %*
would allow you to invoke a Perl script as follows:
script.pl 1 2 3
If you want to eliminate the need to type the extensions, then do the following:
set PATHEXT=.pl;%PATHEXT%
and the script could be invoked as follows:
script 1 2 3

Things that are different (by design, by accident or otherwise)
Typos in the help text
In the NT help text, the description of parameter parsing inside the openCommandString incorrectly states that
%4 gets the second parameter. This was changed in 2K/XP/K3 to say
%3, which is correct.
We did note something that is CONSISTENT across
NT/2K/XP/K3. The misspelling of "association" as "assocation"
has survived from Windows NT on up to and including Windows Server 2003! That's an amazing 7 years and no one has caught it (yet)!
