You can also hide your files in windows through the command prompt.
First open the command prompt (start > run > cmd).
Then give in the command:
attrib +h d:\filename.txt
This will hide the filename.txt file in the D drive.
Replace the file path with any file path you want to hide that particular file.
To unhide the file use the same command with the –h option like as follows.
attrib -h d:\filename.txt
This will unhide the file.
