Windows 10: How to open multiple 3D-viewer instances simultaneously?

When attempting to open a second `.ply`-file, the current 3D viewer instance is reused, preventing multiple 3D viewer windows from being open simultaneously.I need to compare and analyse pairs of `.ply`-files, but this limitation makes it highly inconvenient.Is there a way to open multiple 3D viewer instances?

How to open multiple images in same instance of Photo Viewer?

Rather than use Photos I changed the Open with to Windows Photo Viewer then double-clicking a file in Pictures opened in Windows Photo Viewer which let me click the arrow to step through all the images in that Folder.

 

How to open multiple images in same instance of Photo Viewer?


Wow, thanks a lot for replying so quickly! In other forums I sometimes have to wait for days for a reply

I also have Builld 10240 and Windows Photo Viewer is already set as my default program for all picture formats.
Stepping through all images in a folder works for me but sometimes I only want to select just a few images in a folder (by clicking on each image while holding down CTRL) and step through this selection in Windows Photo Viewer. When I select 5 images in a folder that contains 100 images and I hit enter, 5 instances of Windows Photo Viewer open up.
Edwin, did I get this right that on your PC this operation only opens one instance of Photo Viewer?

PS: Since English isn't my mother tongue, maybe sometimes my explanations aren't that easy to follow. Please bear with me *Redface

 

How to open multiple images in same instance of Photo Viewer?


I just discovered something weird:
If I select multiple BMP or PNG files, only one instance of Photo Viewer opens up (I haven't noticed this before because most of the time I deal with JPEGs ).
But if the file selected last is a JPG then multiple instances of Photo Viewer pop up.
So even if I select 10 PNGs and then a single JPG -> multiple instances (11 to be exact)
But 10 JPGs and then one PNG or BMP -> one instance
