Making A file of the size you want..

How to make a file of the size you want ?
Let us assume you want to make a file of size 10000kbConvert it to bytes -> 10000*1024 which comes out to be 10240000 bytes
Open calculator (win key+r -> type in calc )
Choose view mode to be Scientific one
Type in 10240000 and convert it to hex it comes out to be 9C4000
Convert this value to 8 digits by padding zeroes to its left
-> so finally it comes out be 009C4000
Open Command Prompt (win key + r -> type in cmd )
Type DEBUG filename.datit'll show file not found error ,ignore itType
RCX -> Enter -> then last four hexadecimal numbers
i.e. 4000 ->EnterType RBX -> Enter -> then first four hexadecimal numbers
i.e. 009C->EnterType W ->EnterType Q ->EnterW stands for write and Q for quitNow check the file you just made by dir command ->dir filename.datUsing the same technique you can make files as big as you wantHere is an image to show how exactly everything can be done
