I made this project because my friends wanted creepy software like this one. In this project I have created not a file locker but a user friendly file attributes changer. I have used two cmd commands.
Command 1 : To hide or unhide
ATTRIB [+A | -A ] [+S | -S] [+H | -H] [[drive:] [path] filename] [/S [/D]]
| + | Sets an attribute. |
| - | Clears an attribute. |
| R | Read-only file attribute. |
| A | Archive file attribute. |
| S | System file attribute. |
| H | Hidden file attribute. |
| /S | Processes files in all directories in the specified path. |
| /D | Process folders as well. |
Command 2 : To change the security access
ICACLS (don't know the full-form)
Code icacls "path/file.ext" /t /deny or grant username : (f)
/T Traverse all subfolders to match files/directories
(f) full control
/deny the user particular rights
Name = demo
Password = pass
Always run as administrator and it always will be.
Caution Warning
- I cannot guarantee a robust application but I have tried and tested it many time in Windows 7.
- Recovery key is the file version 51350.73.4970.938 with dash 51350-73-4970-938
- Last but not the least I cannot be held responsible for any loss of data/monetary.
- The best way is for you try it first on a demo file.
- If you trust it then try it on main stuff.
- I trust your intellectual capabilities and because of that you can overcome any problem.
Troubleshooting
- If anything went wrong run these code in run window
- Including double quotes and *.* for all file and folder
- Attrib /s /d -h -s "C:/path/*.*"
- icacls "C:/path/*.*" /t /grant everyone:f
- Access denied means you don't have rights to change the attributes; first unblock it.
- Drawbacks are that you can enter only one file name in the file name box.
Example : my.mp3 (correct)
Example : my.mp3,you.mp3,all.docx (wrong)
Read The Read me file properly
Ok that was the basic info needed to start. We will require three forms.
