What is the folder CustomDestinations?

My recent documents folder contains a mystery folder named CustomDestinations. The files are variable size, in the low kB range. The filenames are undecipherable as far as I can see. Here is a typical one:

5afe4de1b92fc382.customDestinations-ms

Clicking Open With is not instructive, and kind of implies I need to go to the apps store to find something to open them.

Anyone know what they are? Can I get rid of them safely?

(I use Classic Shell if that may be relevant to the question but the ms suffix kind of tells me no,)

Wow! I'm glad I asked here first even if perhaps jumping protocols. Those Rabbit Trails on the referenced link are sure impressive, and basically too much or too little information for me. Your "Might" was spot on..... But while that is so, I at least know they are MS creations, and I suppose I better leave them alone.

Solved enough.

Thanks.
