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
- The file extension. 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.
- More than one file extension may be associated with the same
- e.g. both the extension .JPG and the extension .JPEG may be
associated with the File Type "jpegfile"
- At any one time a given file extension may only be associated
with one File Type.
- e.g. If you change the extension .JPG so it is associated
with the File Type "txtfile" then it's normal association with
"jpegfile" will disappear. Removing the association to "txtfile"
does not restore the association to "jpegfile"
- File Types can be displayed in the Windows Explorer GUI:
[View, Options, File Types] however the spelling is usually
different to that expected by the ASSOC command e.g. the File
Type "txtfile" is displayed in the GUI as "Text Document"and
"jpegfile" is displayed as "image/jpeg"
- Executable program to associate .ext with.
- Delete - Delete the association.
- 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.
- Force - Force overwrite or delete without questions.
- Quiet - Suppress interactive prompts.
FTYPE - Edit file types (used in
file extension associations)
ASSOC - Change file extension
Equivalent Linux BASH commands:
export - Set an environment variable
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
Removing a File Association:
ASSOCIATE .SQL /d
