Copying is a bit of problem in Windows when you have less of ram / memory and more of data ( i.e. 1-2 Gb or more ). Since Windows Copy program uses the MFC  classes,  chances are when you are doing a huge copy the machine will definitely get slow when you are low on resources.

Introducing  Fast Copy, a program which is said to be the fastest Copy/Delete Software on Windows. This program takes advantage over windows copy by using  only  Win32 API and C Runtime.

This program uses the funda of user defined Buffer copy which makes sure it had copied a defined amount of data before it starts writing.  So it reads and then write  again reads and then write.

FastCopy Intro

However when you copy between 2 different harddisk it uses the parallale path concept and runs thow threads. One for opying and another for wirting. Since Writing is on different HDD the perfomance doesnt degrade.

I did a test run in which I copied data of 1 GB .

• Using Windows it took 3 min 15 seconds
• Using fast Copy with 32Mb buffer : 134.66 = 2 Min 14 seconds
• Using fast copy with 128 MB  buffer : 125.27 sec = 2 Min 5 seconds
• Using fast copy with 512 MB buffer : 128.85 sec = 2 min 8 seconds
