Windows 10: Associate/Open files with portable apps : still not possible?

Hello, when i tried 10 (about 6months ago i'd say), what made me go back to 7 was that issue :

It wasn't possible to associate (& therefore open) filetype with portables apps. Is that still the case?

File associations broken post Anniversary update

Has the Anniversary update broken the way file associations use to work for portable applications. Prior to the update, any portable program could be set as the "default app" (eg browser, video player) once it had been associated with a file extension eg.
Smplayer associated with .avi, and it would be visible in the drop down list of known video players. But now it looks like it doesn't applear in the drop down list, unless I manually set many file associations to a portable app, and then it _might_ appear.

Another issue is when I change the "default apps", not all the file extensions are changed to the new app, eg. setting smplayer to be the new default app for video player does not change .divx or .m4v which is still set to the built in "Movies and TV".

Is this problem also related to Anniversary update removing classic shell?

 

Microsoft Edge Overrides Default Program for PDF

Thank you for your help first.

I'm using a portable version of Acrobat DC, unfortunately it seems only the last method works( http://www.winhelponline.com/blog/edge-hijack-pdf-htm-associations/ )by
adding a registry value NoOpenWith. But the problem now is after open a PDF, the software simply won't open another unless I close the previous one. And when open the first PDF file, the icon of the file changes, so I guess the value of the registry has changed
during the opening procedure?I really prefer to use portable apps if possible. Do you have any idea how to handle this?

Thanks.

 

Could be, installed programs have to write to the Registry and the portable apps I've used didn't.

 

I've done this on Windows 10 recently, as I associated the portable version of Irfanview as my image viewer for certain image file types.

In File Explorer, right-click your file, then go to Open with, then select "Choose another app". You then have to click near the bottom of the dialogue box (scroll if need be) and choose "More apps". Then scroll to the bottom of the box that comes up and choose "Look for another app on this PC". This will open up a file chooser, so go and find the executable of your portable app and select. Then click the box that has "Always use this app to open *** files" (*** being the file extension). The application should be associated with the file type.

 

I'll try again ASAP. But sometimes the portable app isn't launched by its main exe file, it's launched by another exe which generally display the logo of the maker. Is that your case? Guess not.

 

Create a custom entry with the portable .exe as path; similar to this:
