YSM (DAF) file cannot be opened

In some cases, after several Windows Update, YSM file for the Studio Manger V2 or DAF file for the DME Designer cannot be opened by double clicking it. And it shows a pop-up like the right.

It is not a problem because of a file failure or a compatibility issue between the program and the data. File type registration of the OS was not managed correctly.


By the way, YSE file for the Editor software cannot be opened by double click. It needs information of Studio Manager (its host software) to start up and to be opened from the "Open..." menu of the Editor software.




Here is the procedure to solve the problem. This is about the Studio Manager but the procedure is same for the DME Designer.

1) Select "Folder options" in the Tools menu of the explorer, and "Folder options" dialog box will open.


2) Click the "FileTypes" tab.

3) Select the "YSM" from the Registered file types list. ( It is easy to access YSM by pressing "Y" key on any list. )

4) Click the Advanced button, and the "Edit File Type" dialog box will open.



5) Slect the "open" in the Actions area, and click the Edit button, and the "Editing action for type" dialog box will open.







6) The "Application used to perform action" area should be as follows:

C:\Program Files\YAMAHA\Studio Manager\SM2.exe %1



Enclose the above strings within double quotes as follows:

"C:\Program Files\YAMAHA\Studio Manager\SM2.exe" "%1"

If the Action area is blank, input "open".

7) Close all dialog box.
