Friends, nice to meet you on my blog... Here I have giving a fantastic trick to create Undeletable folder. We faces dilemma when we works on network computer & someone deletes our folder remotely, then obviously we felt into snag.

If you’d like to avoid anything similar happening in future, then follow simple steps…

     1. Start Menu> Run or press Win+R > type CMD

2. Select folder or create new (i.e. MD foldername) one where you want.

3. Go into selected folder using “CD foldername” command

4. Create folder using this syntax,

• md .\con\                OR
• md .\lpt1\                OR
• md .\com1\

5. You will be come across folder created by name Con or Lpt1 or Com1 respectively.

6. One of them is sufficient for protect the folder.

7. If someone try to delete this folder then explorer shows following window,

8. If someone move this folder to another location then explorer shows following info(don’t afraid even somebody copied this folder on another location then it only copy the folder without inside content.)

9. Up to this stage I have given information on how to create this folder. Now, we focus on how to delete this folder. To delete particular folder you would follow syntax in DOS,

Undeletable folder : Inaccessible & Accessable both

When we need to hold some important data with us. To protect data we use varies software, but they bounds us in such way that we can't use another software for unlocking same data. But I feeling glad to give you software free trick to protect your Data Folder.

1. Open command prompt (or Press Win key+R, type “cmd” in the Run dialogue box and hit “Enter”).
2. In command prompt type the following syntax:

cacls /e /c /d %username%

      For instance, command would

cacls Private /e /c /d %username%

 

That command will make the folder “Private” inaccessible and un-deletable. If any body tries to access the folder or delete that, the following message will be shown:

Now when you want to access the folder for your need then type the following

Syntax in the command prompt and hit “Enter”:

cacls /e /c /g %username%:f
For example : Cacls Private /e/c/g %username%:f

This will return the folder in its normal form.

Tip :This trick works in both Windows XP, Windows 7 as well as in Windows vista. But the file system must be NTFS.
