FastCopy is the Fastest Copy/Delete Software on Windows.

It supports UNICODE and over MAX_PATH (260 characters) file pathnames.
It automatically selects different methods according to whether Source and DestDir are in the same or different HDD.

Diff HDD	Reading and writing are processed respectively in parallel by separate threads.
Same HDD	Reading is processed until the big buffer fills. When the big buffer filled, writing is started and processed in bulk.

Because Reading/Writing are processed with no OS cache at all, other applications don't easily become slow.
It can achieve Reading/Writing performance that is close to device limit.
Include/Exclude Filter (UNIX Wildcard style) can be specified.
It runs fast and does not hog resources, because MFC is not used. (Designed using Win32 API and C Runtime only)

Ultracopier is free and open source software licensed under GPL3 that acts as a replacement for files copy dialogs. Main features include: play/pause, speed limitation, on-error resume, error/collision management ...

TeraCopy is designed to copy and move files at the maximum possible speed. It skips bad files during the copying process, and then displays them at the end of the transfer so that you can see which ones need attention. TeraCopy can automatically check the copied files for errors by calculating their CRC checksum values. It also provides a lot more information about the files being copied than its Windows counterpart. TeraCopy integrates with Windows Explorer's right-click menu and can be set as the default copy handler.

• Copy files faster TeraCopy uses dynamically adjusted buffers to reduce the seek times. Asynchronous copying speeds up the file transfer between two physical hard drives.
• Pause and resume file transfer activities Pause the copy process at any time in order to free up system resources and continue with a single click.
• Error recovery In case of a copy error, TeraCopy will try several times to recover and, in the worse case scenario, will simply skip the file, not terminating the entire transfer.
• Interactive file list TeraCopy shows the failed file transfers and lets you fix the problem and recopy only the problem files.
• Shell integration TeraCopy can completely replace the Explorer copy and move functions, in turn enabling you to work with files as usual.
• Full Unicode support.
• Windows 8 x64 support.
