These are small utilities, but fairly useful - and can
be used to check the MD5 checksums provided for software distributions. 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.
- The full source code, in a single C++ source file for Visual Studio.
- Defaults to copy files very quickly, optionally calculating MD5 and optionally verifying
- Defaults to calculate the MD5 of a single file with no copying done
- Defaults to just display the MD5 of one or more files
