'''FastCopy''' is [[computer software|software]] for [[file copying]] on [[Windows]]. Originally [[open-source software|open-source]], under the [[GPLv3 license]], later releases were [[freeware]] with a note that "Due to various circumstances, distribution of the [[source code]] is temporarily suspended". In version 5.0.0, licensing was changed for a newly added Pro version with additional features, and separated the [[use case]] in non-domestic environments, while previous versions allow using FastCopy in workplace.<ref name=help/>

There are [[32-bit|32-]] and [[64-bit]] versions, which run under [[Windows 7]] and later, and [[Windows Server 2012]] and later. The total size of the executable and [[Dynamic Link Library|DLL]] files comprising 64-bit version 4.1.7 is  1.3MB.<ref>Download and extract to see file sizes</ref> It can run as a free-standing [[portable application]] or be integrated into the [[Windows shell]], and claims to achieve  reading and writing performance  close to the device limit.<ref name=help>{{Cite web |title=FastCopy Help (en) |author=H.Shirouzu |website=FastCopy Lab |date=26 June 2022|url= https://fastcopy.jp/help/fastcopy_eng.htm}}</ref>

In a test conducted in 2008 by [[lifehacker]], Fastcopy was several times faster than its rival [[Teracopy]],<ref>[http://lifehacker.com/5060849/transfer-files-lightning-fast-with-fastcopy Transfer Files Lightning Fast With FastCopy]</ref> a program with similar functionality. However, both programs have been updated since then. A more extensive comparison was performed between TeraCopy v2.07beta, KillCopy v2.85, FastCopy v1.99r4, [[SuperCopier]] v2.2bet and published on a forum in 2009.<ref>[http://forums.whirlpool.net.au/forum-replies.cfm?t=1337937#r4 Is TeraCopy/Equivalent worth using?]</ref>

In Microsoft Windows prior to [[Windows 10, version 1607|Windows 10 v1607]], programs that use the [[Win32]] [[API]], such as [[Windows Explorer]], do not support path names longer than 260 [[UTF-16]] characters; later versions of Windows allow this to be changed via the [[Windows registry|registry]] or group policy.<ref>{{Cite web |title=Naming Files, Paths, and Namespaces - Win32 apps |author= |website=Microsoft Docs |date=15 September 2020 |access-date=25 September 2020 |url= https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file#file-and-directory-names}}</ref> FastCopy does not use Microsoft's API and places its own calls to the [[NT kernel]], allowing operations with path names longer than 260 characters.

In 2015 FastCopyV2.11 ([[BSD licenses|BSD License]]) was ported to [[Mac OS X]] by Japanese PostProduction L'espace Vision. It is sold on the [[Mac App Store]] as "RapidCopy". In 2016 L'espace Vision released the Linux version of "RapidCopy for Linux" on [[GitHub]] under a [[BSD_licenses#2-clause|BSD 2-Clause license]].
