I have got the most strange problem, I downloaded 4 images yesterday, then cut and paste them using Nautilus into a sub-folder of my
Documents area. I then closed Nautilus and went on with my normal business.
However later on I needed to send the images to someone so I went into the folder with the images using Nautilus, but they weren't there! And this is where it gets even stranger, the images show up, though not their thumbnails, when I use Firefox's file chooser for instance, or another program's file chooser, in fact if I open the Image Viewer and then use its file chooser to find them I can open and view them perfectly fine.
The other odd thing is that Nautilus half knows they are there, because my first reaction was to think that my computer just ate them somehow, so I redownloaded them, and pasted them into the folder where the previous ones should have been. Nautilus asked me if I wanted to replace the old with the new and it even showed me the correct thumbnails this time!
I am also able to see that the files are present in Terminal using commands such as
tree, I can also
cat the contents so the files are readable and everything.
Here is the
stat output for one of them:

It was suggested to me that this could be because of a filesystem error, so I ran
fsck on boot and this was the output in

I will soon do the same checks from a LiveUSB, when I have done that I will update this question with the information on how that went. If this is useful to anyone the output of

So I am using LVM. I am running Ubuntu GNOME 16.04 with GNOME 3.20. What could the problem be and what shall I do about it? The place to which I downloaded the second batch of the same files still shows them (my
I have now tried installing
nemo, and the issue is also present there.
And there is something even more interesting that I have discovered, if I search for the file names using
nemo, they do come up in the search results, their thumbnails show correctly, and I am able to open them!
The output of

If I use the
mv command to rename the file, it still does not show.
I have now looked again and the files have reappeared along with a lot of other files which were missing from that folder! I hope them reappearing hasn't made any others disappear, is there any way I can check? What could be causing this?
