So friends,today i am going to a interesting thing ie. to make your files invisible in xp,7,8,vista
1.open cmd by typing it in the run command or by just searching it.
2.then type(in the cmd) attrib +h +r +s /s /d J:\*.* here J represents you resp. directory.
3.suppose if you want to hide all the files then follow av\bove command.
4.Or else if you want to hide a specific extension file then just replace *.* by *.(your resp. extension)*
5.then if u want to unhide then type attrib -h -r -s /s /d J:\*.* or the resp directory or the extension
enjoy!!!
