Hello everyone. I've been away from things a bit, so I've just now read this thread. Here is what you can do to make TeraCopy kick in when you do a Drag-and-Drop.
Like nudel says, go to Settings/Filetypes/All Files and Folders. Edit that, and make sure the Events tab is active. Double-click the first entry which is Drag-and-Drop.
When the Edit box pops up, replace [copy movewhensame] with
[C:\Program Files\TeraCopy\TeraCopy.exe Copy {allfilepath$|filem} {destpath}] , then click OK to save the change. Of course, do NOT use the [ ]s , just the text only.
Now, just click on OK, then close to get back to Opus proper. So, from now on, when you drag and drop a file, TeraCopy will kick in, and do the work for you. The only thing is, that it will NOT do a move using this method. It will only do a copy, no matter what drive you are dropping the file on.
If you want to be able to do a move, then you will have to do more editing. Go back again to to Settings/Filetypes/All Files and Folders. Edit that, and make sure the Events tab is active. This time, double-click on the Drag-and-Drop + Shift entry. The command to be entered this time is
[C:\Program Files\TeraCopy\TeraCopy.exe Move {allfilepath$|filem} {destpath}] , again without the brackets [ ] . Save everything as before, and now when you do a Shift + Drag-and-Drop, TeraCopy will do a move, no matter what drive you drop the file on.
OK, that should cover it, but if I've made a mistake, just let me know, and I'll see where I went wrong, but it should work. It works for me, using Opus 9.1 .
