The program will replace Explorer by default while it’s running in the system tray and one odd thing is it keeps expanding the copy dialog window to fit in long file names. The earlier 0.3.1 did work well enough to test though, so bear that in mind. We had a few problems with the latest version of UltraCopier 0.4 as it kept throwing up errors during transfers and then crashing. A portable version is made available using the installer and users of Total Commander and Directory Opus have options to integrate TeraCopy into those file managers. It can also pause, skip and verify copied files using CRC32 in addition to dragging and dropping files onto the copy queue. TeraCopy is one of the most popular tools around because it can completely replace Windows Explorer as the default copy handler and also adds itself to the context menu.

Buffer size and Transfer speed can also be controlled from the Configuration window.

Most actions are accessed from the system tray including adding a new copy task and it has the standard pause / resume / skip buttons in addition to the copy list and several options to deal with errors or file collisions. SuperCopier is an open source transfer utility and is quite similar in looks and functionality to UltraCopier apart from this tool seems to be more stable. It’s a multi threaded program allowing many files to be copied in parallel and has several of the functions you might want from a 3rd party copy program such as pause, resume, verify, profiles, file / directory filtering, multiple sources at once and full command line support.

RichCopy is actually a tool developed at Microsoft and was used internally by them to copy files for several years before being made available to download.
