Vexing Problem - Hidden Video File - I can play it - I can't delete it

Used following Terminal command - it revealed the file exists on network connection - but renaming file and directory did not make video go away from import window

find . -type f -iname "*pm02*"

Was able to locate "Reveal in Finder" command by right-clicking "CANON" toward top left of import window. Once again said video file nowhere to be seen - yet plays in the import window.

I'll make a YouTube video documenting how incredibly asinine this is

Found the problem.

I'll quickly recap the test I was doing before stating what fixed it. I had filled the 64GB SD card with random pictures, then deleted all those pictures using Finder. The idea was that, by copying all that data and deleting, I could be sure that that the unwanted video would be written over and deleted. After filling up the SD card and deleting every file using Finder the SD card appeared empty - no files could be seen in Finder or in my video camera - however, despite this, the SD card was almost completely full - having only a few MB left. My CANON video camera could only record a few seconds before the SD card was 100% full.

I continued on with my original test.

Since I had a very short video I figured I'd continue - so I placed the SD card into the slot so that the Import window in FCPX would be triggered. I was very curious to see what would now be reported in the Import window. By this point in time I knew something was amiss with the SD card - and I was expecting the Import window to see scads of files that should be deleted. That never happened. After popping the SD card into the slot of my MacBook I got the beachball in FCPX (which was normal), however instead of seeing a beach ball for 20 seconds or so - the beach ball remained for the next 8 to 10 hours before I finally forced FCPX to quit - triggering a crash report to be sent to Apple.

The next thing I did was format the corrupt SD card using my CANON video camera.

This fixed the problem.

I can pop the SD card into my computer and I only see the file I expect to see show itself in the Import window of FCPX.

In the end - it wasn't a FCPX problem.

Although, it was odd that FCPX was the only program I encountered that was able to see a corrupt video and play it - Finder couldn't see this, Terminal couldn't see this and my Canon video camera could not see this file - just FCPX.

New operating procedure - format (or initialize) the SD card regularly.

Well, that was a serious pain - but at least I have a sense of knowing what really happened and how to fix it.

Yeah, still don't know what you mean. But, the question is this: I desire to delete a video, therefore I need to know the LOCATION of that video. I'm feeling pretty negative about this at the moment - since, I have a video that I can play on my computer, but can't delete for lack of extremely simple information: location of said video.

Disconnected from network drive - video still shows up in import window.

I've never been a fan of hiding directories. It's ridiculously simple to SHOW THE DIRECTORY OF WHERE A FILE IS LOCATED. HIDING FILES DOES NOTHING BUT WASTE TIME. SO WHAT NOW?

Used different SD card - video does not appear.

Okay so it seems reasonable that the video I want to delete is on the card - except for the fact that the video isn't there (or is hidden in some way) when viewing with finder, terminal or the video camera. It's not really making sense.

I'm filling up the supposedly empty SD card with random pictures from my SSD. Then, I'll erase everything, record a short video and insert into the SD slot on my MacBook (to invoke the import window). If the import window does not show the unwanted video then it's most likely that the unwanted video was on the card - and invisible.

If that's really true then it's just plain scary.

@Luis Sequeira1 - given how long ago I created that video (Sep. 2016) it's hard to say how it may have ended up on the SD card. Perhaps I had used the SD card to transfer the file from one place to another. But, yeah, keeping things tidy by regularly formatting in the camera will probably save a lot of heartache and confusion in the future.

Doesn't work - see screen capture

Have no idea what "externals" are - extremely confused - here is a picture of my desktop.

What do you mean by "top level" of external drives?
