sometimes on my computer hard drive, files "vanish". But they later show up, What causes this?

Sometimes a file is created  temporarily so a particular program or application can run properly.  When the program ends, the file is no longer needed and might automatically be deleted.  If you use the program later on, or return to the website, it will be created again.\n\nplrr

No, they are temporary files so they would go away, anyway. I think it is impossible even with a program.

to help you with this problem, you should use a program called file monitor which would tell you exactly what is going on.  Or you creatures tried uninstalling the program.

They are probably gone for good.  You could use some special software or pay someone lots of money to look through your hard drive, but chances are they have been written over by now.

Maybe this is a virus or an adware/spyware, to prevent this delete all of your Temporary Files in your computer, or let the anti-virus/anti-spyware to do it for you

Yes please re-installing the software , the portion on the Hard-drive the files was copied is corrupt , after this it will be ok, or it may be your memory need to be change at worst scenario after the re-installation if it still happen , your files are saved if you only uninstall and re-install but don't delete your crated files

that's pretty standard.  there are A LOT of files that are setup in the background to make other things run properly.  the only ones you should get rid of are the files/programs that you KNOW are not involved in the day-to-day running of your computer.  if you can't be sure of what you're deleting......DON'T DELETE IT!!!

clear drive's lens by using a lens clearing disk or lotion. if that doesnt help , get checked your harddisk by the manufacturer.

You don't want to remove a file simply because it's contiguous, or "all-together".\nRun a defragment utility to reallocate the used space on your hard drive.  That will also rearrange the fragmented files so they will become contiguous.  Instead of being scattered around in bits and pieces across the drive they're now all-together.

What you have is a problem with the hard drive. Either the operating system on the drive has been corrupted, files necessary for it to run have been deleted, or the drive itself has failed. Deleted or corrupted files can be caused by age, a virus or trojan, or unjudicious "cleanup" of the wrong files.\n\nEither way, unless you know a lot about computers, you'll need to either replace the hard drive or format it. And both these things will require you to re-install Windows from a CD, which you say you don't have.\n\nSorry - sounds like time to get a new computer :( and he's lost whatever data was on that one.

The data is not earsed from the disk but the pointers (memory address) to the data (located in the FAT?) gets erased. The actual data stays there until you do 'Disk fragmentation'.

Don't you just love computers? The file may already have been deleted.To make sure of the correct path, file name, is saying ( the computer is not finding the file) You can go to SEARCH, type the file name in and modify your search to all hidden and sub-folders. if it is there and will not let you delete, it is part of the operating system..Or another program in use..good luck.

Usually lack of memory or space on the hard drive.  Try Cleanmgr.exe - its in Windows to clean up your hard drive. you may need to get more memory in your machine.\n\nWhat is the question given by the computer ?

I have this problem too for my usb flash drive. Those programs that claim to get rid of them don't work, so don't waste your time. Sorry I can't be of more help, but I thought I might save you hunting for special programs. I'm sure that there is some setting in the registry (Start>Run>regedit) that controls this. If you could find it and delete it, it would probably fix it.

Try typing the name in "search" that should bring up all the files associated with it then you can delete them.
