To Open a File by Double Clicking in Explorer¶
Select the Customize command under the Tools menu.
Select the File page.
Click the Associate with EmEditor button.
Click the Add button.
Enter the file extension you want to associate in the Extension text box, enter any name in the File Types text box, select an icon from the Sample Icon from This File text box and the Current Icon list box.
In Explorer, icons whose extension have been associated with EmEditor will change to the specified icons, and double-clicking on those icons will open those files with EmEditor.
If you try to enter an extension already associated with another program, the message box “This extension is already associated with ‘…’. Are you sure you want to change the association?” appears. Selecting Yes will change the association, and double-clicking the file will no longer run the old associated program. However, deleting the new extension in the Associate with EmEditor dialog box will restore the association with the old program.
If you do not want to change the association, you can still open a file in Explorer by selecting EmEditor in the menu displayed by right clicking on the file.
