option turned on? To change it back so it prompts you to specify a program each time, just delete the association for that file type ASSOC .ext= [where .ext is the file extension]. Now when you double-click on a file of that type, the system will ask you what program you want to use. Using the ASSOC command will edit values stored in the registry at HKey_Classes_Root\. Therefore it's possible to use registry permissions to protect a file extension and prevent any file association changes. Examples: View file associations: ASSOC .txt ASSOC .doc ASSOC >backup.txt Add file associations: ASSOC .txt=txtfile ASSOC .DIC=txtfile ASSOC .html=Htmlfile Delete a file association: ASSOC .html= Repair .REG and .EXE file associations: ASSOC .EXE=exefile ASSOC .REG=regfile Digging through CLASSES_ROOT entries often reveals more than one shell for the same application, for example [open] and [play] these may have subtle differences, changing the default action for a file extension may even invoke a different executable. ASSOC is an internal command. “Of all forms of caution, caution in love is perhaps the most fatal to true happiness” - Bertrand Russell ASSOCIATE.exe 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. tải về 1.67 Mb. Chia sẻ với bạn bè của bạn:
