Hello forum,
Really loving this program but how to I configure it to open with other (ALL) applications? Example: When I have say, avidemux running and go to search for a file, Windows Explorer still opens? Appreciate the help. 
In your preferences in the "Opus start" tab you have the options for the Explorer replacements.
thanks abr, found it...although most programs still open with Windows Explorer when I use a app specific command. Hmmm...
Some programs explicitly launch Explorer rather than the program associated with folders, so it might be that.
right, that's what I am trying to stop..lol. Is there a way to do this or do I have to live with Windows Explorer still opening for most programs?
It depends on the program and how it launches the folders. I don't know what avidemux does, sorry. It may be worth asking the authors of it what they do.
A lot of programs use ShellExecuteEx on the folder and pass the "open" verb (which opens Explorer) instead of passing a NULL verb (which opens the default file manager). Some programs literally run Explorer.exe (which Opus can intercept in some cases but not all). Others use yet more different methods, only some of which it's possible to intercept...
Am I allowed to jump in and hijack this because I have a similar issue?
In my case another program, JDownloader, insists on using Explorer to "Open Folder". I want Opus to do the job.
I will pursue the clues here to see what I can do, but if anyone is familiar with JDownloader and knows how to beat it into submission I would be grateful for advice.
As Leo said, it really depends what they're doing to open the folder. The best option is generally to contact whoever makes the other program, and ask them to change how they're doing it.
FWIW, when using uTorrent, I right click on a torrent and select "open containing folder" which opens in Opus most of the time, occasionally it will open with explorer... repeating the process always opens in Opus though. Strange!!!
I did that just before spotting this discussion.
But feedback elsewhere usually lags what happens here by a large margin.
If you want a technical description of the problem, or somethign you can point the developers of the other app too, this is a nice summary.
