Get "M:\.." Link from selected Object via UIX

M-Files API - GetPathInDefaultViewEx3 Method

Great, is this path stable or can it change over time?

It depends what you mean by stable. Probably not entirely.

For example: the M drive is common on most machines but, at least theoretically, the drive name could be different. Also: the path contains the client-configured vault name which, at least theoretically, could be different on two different machines.

I don't recall off the top of my head the rest of the path syntax but I have a recollection that it uses the built-in ID view with then the object type and id, maybe a version indicator, and I don't recall whether it includes file data... Those items are more static, perhaps.

These paths are not guaranteed to be usable between machines, for example. For that you may want to use the "m-files://" Uri format, or the newer HTTP format that gives you the option of how you'd like the link to open (Web vs Desktop). 

Thanks for explaining! But there is another variant, paths generated through vault search, what about them? Is such a path temporary?

As i mentioned before, the m-files:// links dont work in a file open dialog of an app..

Can you show an example? 

(and I realised that you did show the format above so I could have confirmed my recollection from what you posted, but let's not go down that route right now...)
