dd for windows

This version does not actually do any conversion but it allows the flexible copying of data under in a win32 environment.

According to Wikipedia dd means the following

“In computing, dd is a common Unix program whose primary purpose is the low-level copying and conversion of raw data. According to the manual page for Version 7 Unix,[1] it will “convert and copy a file”. It is used to copy a specified number of bytes or blocks, performing on-the-fly byte order conversions, as well as more esoteric EBCDIC to ASCII conversions.[2] It can also be used to copy regions of raw device files, for example backing up the boot sector of a hard disk, or to read fixed amounts of data from special files like /dev/zero or /dev/random.[3]

The name dd is an allusion to DD found in IBM JCL, and the command’s syntax is meant to be reminiscent of it;[4] in JCL, “DD” stands for Data Description.[5] The Jargon File states that it is rumored to have been based on IBM’s JCL, and the syntax may have been a joke.[4] Another explanation of the name is that dd is named “dd” because “cc” for “convert and copy” (as mentioned above) was already taken by the C compiler.”
