No on line back up because I really don't know how and have never tried.

It sounds like corrupt directory map.
The way a computer store data on a disc is it writes the files blocks on the disc. A file will span multiple blocks. They are not always linear or consecutive. A file can be scattered in pieces in multiple locations all over the drive.
Your computer has a file that keeps track of all the pieces and where they are.
When you erase a file you don't actually delete data. What happens is the name is removed form the map which allows new data to be written on the blocks that the "deleted" file occupies. So you never really erase data, you overwrite data.
If the map gets corrupt you can lose files because the computer can no longer find them.
Have you run disk utility repair yet?
My advice is that you not create, modify or do anything else that will write data to the disk.
The files are still there, just a bit lost right now. The more things you write to the disk the more likely you are to start overwriting them.
