A Reason Behind the Con Folder Creation in Windows
We all know that we can’t create Con, Folder in windows. not only con but also ” PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more”.Here i am going to explain why you can not create the con folder in windows.
Reason:
We can not create folder with con,aux, nul because these are reserved keywords used by DOS. 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.Keywords and Their corresponding Functions:
| Reserved Keywords | Function |
|---|---|
| CON | Keyboard and Display |
| PRN | System list device, usually a parellel port |
| AUX | Auxiliary Device,usually a serial port |
| NUL | Bit-Bucket Device |
| A:-Z: | Drive Letter |
| COM1 | First Serial communications port |
| COM2 | Second Serial communications port |
| COM3 | Third Serial communications port |
| COM4 | Fourth Serial communications port |
| LPT1 | First Parallel printer port |
| LPT2 | second Parallel printer port |
| LPT3 | Third Parallel printer port |
