Folder hide i cant see some folder in my harddisk but if i tried in dos using dir/a command then its ok. but i cant change its attribute also (only for those in which i have space)

Are you talking about... ADMINISTRATOR'S PASSWORD, WORK GROUP PASSWORD to Server Database Login???
If you are talking about WINDOWS LOGIN at boot... try F5 or F8 to choose... DOS PROMPT(command prompt; safe mode command prompt is Ok as well)
Use the "CD" command to "change directory"... to change to the C:\WINDOWS directory---i.e...C:\Users\USER> cd C:\WINDOWS
Then use the command line... C:\WINDOWS dir /p/w
Now.... LOOK CLOSELY-- for "any files" with the extention of----
.pwd (this is the extention for "password files")
Simply......(example command line)---- del C:\WINDOWS\*.pwd
Type the word.... "exit" after first available Command Line to EXIT DOS... use CTRL-ALT-DEL to REBOOT

Hi,
It is due to virus activity. Some virus make the contents of the drive hidden, thats why user can't see the files. This can be fixed and data would be available to you. However, there are number of steps involved.
It is suggested that go to FOLDER OPTIONS - and select 'SHOW HIDDEN FILES & FOLDERS' and uncheck/ Deselect 'HIDE PROTECTED SYSTEM FILES'.

It would show the hidden files/ folders, if the system not infected Otherwise, from the clean/ virus free system you can see your data and copy all the required files/data. Select the required files and right-click and change the properties of the file by un-checking the hidden attribute. Please note that you can not change the properties (hidden attribute of the files) if the files are marked as system files. To change the attribute of such folders you can download and use iReset.

Also, make sure that you have a good antivirus installed and its updated. Scan your system and clean it.

Let me know if any further clarification/ assistance is required.

Hope it helps! Good Luck! Thanks for using Fixya!

you want to open commamd prompt? press start+R and type cmd

Use the following command in command prompt and your problem will be gone for sure (it will not delete any content) :-

attrib -r -s -h g:\* /s /d

Note:- (replace "g" letter in the above command by your 500gb Roco Hard disk drive letter)

To open command prompt press WindowKey+R and write cmd in the box and press enter. Then write the above command on the command prompt window and press enter.

Some files are also system hidden and they can only be seen using this command.

---->Attrib command is use to change the Attributes of file/folder to showup(unhide) in windows. use attrib/? at command prompt for help.

Hope this will help....cheers:)
