Disappearing Folder/Files
The issue I encountered is the following:
I opened a number of files from a folder within My Documents (specifically 2 PDFs and a .docx file). While taking notes and making some highlights in the PDF documents, I tried to save my changes but encountered an error message stating that I was unable to access/did not have permissions to that folder any longer. Subsequently, I reopened the sub-folder and found that the folder containing the files I was working on no longer existed.
This struck me as odd, since I did not remember touching that folder since I opened my documents. This led me to believe that I must have accidentally sent my folder to my Trash bin, but upon examining my Trash folder, the folder was not there, nor were any of the files (and my Trash bin was not emptied).
After checking the Trash bin, I performed a search for the individual files from that folder to see if I had somehow managed to move those files to a new location, but alas, they were nowhere to be found. I performed multiple Spotlight searches for multiple documents that were stored within that folder, however I came up empty on all my searches. Next, I thought, perhaps, somehow, I maybe managed to hide my files without meaning too (which seemed entirely improbable), so I unhid the files on my computer, but that was to no avail.
So, I am a bit flabbergasted at the moment. I did not delete the files, nor did I move them, and I did not hide them - they simply seem to be gone. Does anyone have any ideas about what may have happened, and how I might recover the files?
