A really, really, fast command line program for MD5 checksumming and huge file copying

This has little to do with AxCrypt, but it's fairly useful - and can be used to check the MD5 checksums provided for the AxCrypt distribution. But more interestingly, it implements a very, very fast file copier specifically optimized for RAID and SAN environments where there are many active disks making up a single logical volume. It uses asynchronous I/O to schedule the number of simultaneous requests that you specify, using the buffer size that you specify. With correct parameters it can speed up file copying speed in such environments significantly compared to drag and drop in Windows or COPY or XCOPY. As an extra bonus the MD5 checksum can be calculated on the fly, and optionally used to verify the file actually written to the destination.

To make it easy to use, the same program comes in three flavors, depending which name is used to invoke it. So the three versions below are the exact same binary executable, but the name determines the operating mode and default options selected.

These are command line utilities, just type the program name to find out the full set of options available.

AxCopySum.cpp
The full source code, in a single C++ source file for Visual Studio.
AxCopySum.exe
Defaults to copy files very quickly, optionally calculating MD5 and optionally verifying the copy
AxSumCopy.exe
Defaults to calculate the MD5 of a single file with no copying done
AxSum.exe
Defaults to just display the MD5 of one or more files
