ASSOCIATE.exe (Resource Kit)
One step file association.
This utility does the job of both ASSOC and FTYPE, in one step. ASSOCIATE assigns
an extension directly with an executable application. This is done by automatically
adding a new FileType to the system registry.
Syntax ASSOCIATE .ext filename [/q /d /f] Key .ext : Extension to be associated. filename : Executable program to associate .ext with. /q : Quiet - Suppress interactive prompts. /f : Force - Force overwrite or delete without questions. /d : Delete - Delete the association.
A file extension is the last few characters in a FileName after
the period.
So a file called JANUARY.HTML has the file extension .HTML
The File extension is used by Windows NT to determine the type of information
stored in the file and therefore which application(s) will be able to display
the information in the file. File extensions are not case sensitive and are
not limited to 3 characters.
Example: adding a File Association
To add the File Type "SQLfile"=Notepad.exe and also set the File Association
of .SQL="SQLfile" run this command:
ASSOCIATE .SQL Notepad.exe
Example: Removing a File Association
ASSOCIATE .SQL /d
Note that /d will delete the File Association but will NOT delete the File Type.
File types created by Associate.exe are always given a name in the form xxxfile,
where xxx is the file extension.
