Why did my tracks disappear?

Question

I shift-clicked the X, next to the F for saving a data block; did I just erase all the info from the solve? I thought the tracking info was linked to the Camera, not the video clip?

Also, I moved file locations of both the .blend file and the movie clip file. Moving the movie clip file seemed to "unlink" the tracks from the movie clip, I re-opened the movie clip file and it was now Movie-Clip.001, but at that point the tracks were still there, linked to the camera.

Now, after shift-clicking the X for the movie clip data block thing (and saving, closing blender, and re-opening blender), it's all gone, no tracks, no markers, the camera doesn't move or anything.... I'm going to re-track the movie clips; I just want to know what NOT to do next time. I hope this makes sense.

All tracking information (camera and trackers) is uniquely associated with the video. Why would you want to unlink it? — , Jun 26 '19 at 12:01
The video file does not get saved as part of the file. Blender does not save images in the .blend file. Read Video tracking image missin in other computer also, to re-link your video read: how-do-you-restore-previously-tracked-footage — , Jun 26 '19 at 13:06

To fix the file location issue I did: Outliner > change the "display mode" to "Data API" instead of "View Layer or "Scene" > scroll down to Movie Clips and in there I found the file paths from Movie Clip and Movie Clip.001 and just copy/pasted Ctrl+C / Ctrl+V the correct file path.

~~Still not sure how to fix the deleted solve data/track data.~~

Best I can tell is shift-clicking the X for the Movie Clip data block (deleting the false user) and then saving the blend file permanently deletes the solve/track data and the clip must be re-tracked and re-solved. "Ten four rubber ducky. Over and out."
