Hidden files are not visible (by 13 users)

If this is not something you did on purpose (hiding the files/folders) then odds are you have spyware issues that you should first deal with.

Now to try and get your files visable again, you are first going to have to see if they are marked as 'hidden' files. Click on MY COMPUTER and then on TOOLS/FOLDER OPTIONS and now on VIEW tab click on the SHOW HIDDEN FILES AND FOLDERS, now see if you can see the files/folders. If you can then what you need to do is highlight all the file/folders from that drive that you want to be able to view (select all by ctrl-a for example) then RIGHT CLICK on any file that you have just highlighted and from the menu, select PROPERTIES and now make sure that both READ ONLY and HIDDEN are NOT selected. If they are, then de-select these. Click OK and when prompted if you want to do this for all files in the sub-folders select YES, as you obviously want this action to set for all the selected files.

Once you are done, be sure to go back to the FOLDER OPTIONS and de-select the SHOW HIDDEN FILES/FOLDERS from teh view options as you do not normally want to see the hidden files/folders as these are related to the system and normal deletion of these could cause other problems. This is however, how many bad items will hide themselves, by causing normal file folders to become hidden so be sure you have performed the optimizing and various anti-spyware/malware scans.

Well 1st of all, let me tell you, I had got into same situation for about three times, but found out the solution at last.

The above mentioned solutions won't work [sorry guys but thts the truth]
May be even your Registry editor and Task manager weren't working, right?
