Create a File Attributes Changer / Locker in a C# Windows Application

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

1. I cannot guarantee a robust application but I have tried and tested it many time in Windows 7.
2. Recovery key is the file version 51350.73.4970.938 with dash 51350-73-4970-938
3. Last but not the least I cannot be held responsible for any loss of data/monetary.
4. The best way is for you try it first on a demo file.
5. If you trust it then try it on main stuff.
6. I trust your intellectual capabilities and because of that you can overcome any problem.

Troubleshooting

1. If anything went wrong run these code in run window
2. Including double quotes and *.* for all file and folder
3. Attrib /s /d -h -s "C:/path/*.*"
4. icacls "C:/path/*.*" /t /grant everyone:f
5. Access denied means you don't have rights to change the attributes; first unblock it.
6. 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.

Application flow diagram

Login->username & pass or recovery->Main page->if recovery was used->recovery window.



Main page

Recovery (optional)



Timer=1000 interval

A Dialogue box of the main page is available when the user has entered the recovery key during login.

A valid recovery key will show the name and password.

namespace Locker
{

{
public Recovery()
{
InitializeComponent();
}
int i = 1;
private void button1_Click(object sender, EventArgs e)
{

timer1.Enabled = true;
}
else

MessageBox.Show("Key Does not Match");
}

if (i == 10)

{
