Hide Folder From View( Hiding using Dos Promt)

Way To Hide Folder and Add other Attributes

If you want hide your folder say,
in d:\sample then you have to go to command prompt
go to corresponding folder and type

Attrib "folderName"_+r_+a_+s_+h

or

Attrib "folderName"_+h_+s

after executing the above command.The folder will be removed from sight
to see it again,

Attrib "folderName"_-r_-a_-s_-h

or

Attrib "folderName"_+h_+s

after executing the above command you can see the folder.

Note : Folder name should come within quotations and replace "_" with space.

Explanation:

+R - Use the +R option to make a file read-only. Read-only files may be read but they can`t be changed or deleted.

-R - Use the -R option to change the file protection attribute back to normal (so it can be read, changed, or deleted).

+A - Use the +A option to set the ARCHIVE attribute of a file. When the +A option is used, this flags the file as available for archiving when using the BACKUP or XCOPY commands.

-A - Use the -A option to turn off the ARCHIVE attribute.

+H - With DOS Versions 4 through 6, use the +H option to set the HIDDEN attribute of a file so that it will not appear in a directory listing.

-H - Use the -H option to turn off the HIDDEN attribute.

+S - With DOS Versions after Version 4, use the +S option to set the SYSTEM attribute of a file. When the +S option is used, this flags the file as a command file used only by DOS. The file will not appear in a directory listing. This attribute is generally reserved for programmers.

-S - Use the -S option to turn off the SYSTEM attribute.

after executing the above command you can see the folder.



Security Threat:
If the user tries to access from command prompt he can access its contents.

Locking Folder Without Using Software(Another Way)

Locking Folder Without Using Software Another Simpler Way

Locking Folders:
Consider you want to lock a folder named XXXX in your E:\, whose path is E:\XXXX.
Now open the Notepad and type the following

ren E:\xxxx xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D}

Where xxxx is your folder name. Save the text file as loc.bat in the same drive.
Open another new notepad text file and type the following

ren E:\xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D} xxxx

Save the text file as key.bat in the same drive.
Steps to lock the folder:
To lock the xxxx folder, simply click the loc.bat and it will transform into control panel icon which is inaccessible.
To unlock the folder click the key.bat file. Thus the folder will be unlocked and the contents are accessible.

Explanation:
The actual Process we are actually converting the folder into control panel.
xxxx.{21EC2020-3AEA-1069-A2DD-08002B30309D}
this line will convert the folder xxxx to control panel
and vice versa


Security Threat:
If the user tries to open through cmd prompt he will be able to do it, by going to the corresponding folder by using
cd directoryname command
and then open the file name inside it(which you get by pressing tab)
by command open filename
it will go to open with dialog.from there you can open it.
If dont want to secure at a high level you can use this method
