One click secret method of Hiding files/folder

4:33 PM By Miss Bee

This is the simple but secret method of hiding any files and folder using BAT extension. We will create 2 bat files hide.bat and unhide.bat Just copy the following codes:

Step 1.

Open notepad then paste the following codes
save as hide.bat

(note:you can save it to any name but extension must be .bat)

attrib +h +a +s *.*
attrib -h -a -s unhide.bat

Step 2

Open note pad, paste following codes
save as unhide.bat

attrib -h -a -s *.*

Step 3

After that copy both hide.bat and unhide.bat file to your private folder, where you want to hide files/folder.

Just click hide.bat it will hide everything except unhide.bat And click unhide it will unhide all.

This trick is done using DOS command. You can also remove/copy/move and do lots of things using other DOS commands in the same ways.

What is MAC addresss?

IP address: (Internet Protocol)
· This is also known as logical address.
· IP address allows operating system to be able to communicate with each other.
· For a computer to be able to function in the network it must be installed with a network card and must be set with a proper IP address.

IP address can be set in two ways:-
1. Statically (Manually)
2. Dynamically (Automatically through a DHCP server)

Every computer in the network must have the same network ID and unique Host ID (different Host ID). If the network ID is different the communication will not occur and if Host ID were to be same then communication will not occur.

Subnet mask
· After setting IP address the subnet mask is automatically set.
· It helps us identify the Network ID and Host ID of the IP address.
· Also in high level networking it is used for subnetting where we can transfer the network bits to host bit to increase the number of hosts in the network.

(Note: subnet will represent 255 for Network ID and 0 for Host ID.)
