Windows Registry Editor Version 5.00

3. Go to File > Save As
4. Save it in your Desktop with File name: folderoption.reg
5. Close Notepad
6. Go to your Desktop
7. Double-click the folderoption.reg
8. If it prompts if you want to add the information on the registry, click YES
9. It will confirm that information was successfully entered into registry, click OK
10. You should now be able to modify Show Hidden Files and Folders settings.

I can't see Hidden files/folders in my computer. Even I enable the option "Show hidden files/folders" in "Tools -> Folder Options", its automatically disabled again.

Solution1: Go to your Start menu, click on Run and open up your Registry Editor by typing "regedit" without the quotes and pressing OK.

Once there go to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folde r\Hidden\SHOWALL

Delete the value CheckedValue. (Its type should be REG_SZ and data should be 0 or 1.)

Create a new DWORD value called CheckedValue (same as above, except that the type is REG_DWORD) by right clicking on the right pane->New->DWORD Value. Modify the value data to 1 (0x00000001).
Solution 2: Open regedit and goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
In right-side pane, change value of "Hidden" to as following:

1 - To show hidden file
2 - To not show hidden files

If it doesn't work, then scan your computer with an anti-virus software.
