Powercopy uses a large RAM buffer to sequentialize the copy process: first it reads as many files as it can up to the size of the buffer, and then it writes them.

While useless if you need to copy from one device from another, if you need to make some large copies from/to the same physical device the gain is immense.

There are many advantages in using Pcopy instead of Windows integrated copy command or DOS copy/xcopy:
· More than 3 times the speed: around 300MB per minute read+write with an average HD.
· No HD head whirring (HD seems still), no HD wear.
· Safer: you can copy the content of a folder into its subfolder. This is possible because Pcopy will take a snapshot of the situation before starting so you don't risk to fill your HD recursively. Also automatically checks for self-overwritings (source files going to overwrite other source files)

Actually the real fault is of the Windows copying methods: they use only a very very small buffer (around 512 bytes) which forces the hard disk head to make an enormous number of movements ahead and backwards.

This slows down the copy process enormously and heaviliy wears the hard disk. So in case you need to copy partitions around the HD or if you work with large audio or video files this program is a must.

Furthermore:
· Good feedback while working.
· Supports directories drag and drop for specifying source/destination paths so it's quite confortable to use.
· Both Windows interface and command line use.
