Another way for file associations is commandline. I used these in scripts on some of my servers to fix a network wide muckup due to a problem with word wanting to open with write.exe. Until I rebuild the domain, I am using assoc and ftype to make the default MSword again. It will revert on a logout for some reason I haven't had the motivation to track down.
Code:
C:\Users\vm09>assoc /?
Displays or modifies file extension associations
ASSOC [.ext[=[fileType]]]
.ext Specifies the file extension to associate the file type with
fileType Specifies the file type to associate with the file extension
Type ASSOC without parameters to display the current file associations.
If ASSOC is invoked with just a file extension, it displays the current
file association for that file extension. Specify nothing for the file
type and the command will delete the association for the file extension.
Code:
C:\Users\vm09>ftype /?
Displays or modifies file types used in file extension associations
FTYPE [fileType[=[openCommandString]]]
fileType Specifies the file type to examine or change
openCommandString Specifies the open command to use when launching files
of this type.
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, %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
so to test, create a file called file1.abc. doubleclick it and notice it wont open with any software. Close the msg box.
open a command windows, in win7 you will need to rightclick cmd.exe and run as asministrator.
type in:
Code:
C:\windows\system32>assoc .abc=abcfile
you should get:
Code:
.abc=abcfile
what you have done is told windows that anything with extension .abc is called an abcfile. That is half the work
now type in
Code:
C:\windows\system32>ftype abcfile="c:\windows\system32\notepad.exe" "%1"
you should get:
Code:
abcfile="c:\windows\system32\notepad.exe" "%1"
note where the quotation marks are. You have now said that "abcfile" is going to consist of notepad opening a file(the file you are trying to open is going to replace the "%1")
if you go to the folder of file1.abc you will notice the icon has changed to a Notepad icon.
this procedure is the same as rightclicking a file, choosing "open with" and ticking the "always open files of this type with this application"
