Folder Which We Can't Create-II

Hello Friends, today we will continue with the last post "Folder Which We Can't Create-I". In the last post we are trying to create folder with specific word but we are unable to create that.In this post we will explore the following questions:-

• Why we can't create them
• How to create folder of that name
• How we are able to create them
• How we can delete them

So lets begin with the today's topic and try to find out the answer of above question.

Reason Why we can't create them

The reason behind that con, lpt1.......lpt9, prn, clock$, com1 etc. are the reserve words used  by DOS. These words have different definition for different devices.some of them are given below:-

                             con                 console keyboard and display devices

                             prn                  system list device for parallel port devices

                             aux                  for auxiliary Devices

                             nul                   for emplty or bit bucket device

                             com1               first serial communicator port

                             com2               second serial communicator port

                             lpt1                  first parallel printer port

                             lpt2                  Second  parallel printer port and so on.......

so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is — it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.

How can create folder of that name

After reading the above content now you would understand why folder of those name not created.But as we listen Nothing is Impossible so we can also create folder with all those name with some trick and also see how we are able to create folder with those name.

Steps to create folder with name con

1. Click start button and type cmd or command prompt.

2. After opening command prompt type following command 

                            md \\.\C:\CON

3. Now open my computer and browse the path where you created folder.

Yeah!!!!!!!!!!!!! you have created the folder named con

How we are to create it

• It just is because of UNC (universal naming convention) path. 
• UNC specifies a common syntax to describe the location of  a network resource such as a shared file, directory or printer.
• These convention didn`t exist under pure Dos.
• Syntax of UNC  \\Remote host\sharefolder\resource

How to Delete it
