Originally [open-source](/source/Open-source_software), under the [GPLv3 license](/source/GPLv3_license), later releases were [freeware](/source/Freeware) with a note that "Due to various circumstances, distribution of the [source code](/source/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](/source/Use_case) in non-domestic environments, while previous versions allow using FastCopy in workplace.[1] There are [32-](/source/32-bit) and [64-bit](/source/64-bit) versions, which run under [Windows 7](/source/Windows_7) and later, and [Windows Server 2012](/source/Windows_Server_2012) and later. The total size of the executable and [DLL](/source/Dynamic_Link_Library) files comprising 64-bit version 4.1.7 is 1.3MB.[3] It can run as a free-standing [portable application](/source/Portable_application) or be integrated into the [Windows shell](/source/Windows_shell), and claims to achieve reading and writing performance close to the device limit.[1] In a test conducted in 2008 by [lifehacker](/source/Lifehacker), Fastcopy was several times faster than its rival [Teracopy](/source/Teracopy),[4] 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](/source/SuperCopier) v2.2bet and published on a forum in 2009.[5] In Microsoft Windows prior to [Windows 10 v1607](/source/Windows_10%2C_version_1607), programs that use the [Win32](/source/Win32) [API](/source/API), such as [Windows Explorer](/source/Windows_Explorer), do not support path names longer than 260 [UTF-16](/source/UTF-16) characters; later versions of Windows allow this to be changed via the [registry](/source/Windows_registry) or group policy.[6] FastCopy does not use Microsoft's API and places its own calls to the [NT kernel](/source/NT_kernel), allowing operations with path names longer than 260 characters. In 2015 FastCopyV2.11 ([BSD License](/source/BSD_licenses)) was ported to [Mac OS X](/source/Mac_OS_X) by Japanese PostProduction L'espace Vision. It is sold on the [Mac App Store](/source/Mac_App_Store) as "RapidCopy". In 2016 L'espace Vision released the Linux version of "RapidCopy for Linux" on [GitHub](/source/GitHub) under a [BSD 2-Clause license](/source/BSD_licenses#2-clause). ## Reception Bogdan Popa, who reviewed FastCopy 3.92 in [Softpedia](/source/Softpedia), praised the product as being "An overall efficient and reliable file management tool" and gave it 4.5 out of 5 stars. User ratings by 419 users gave it an average of 4.2 out of 5 stars.[7] On December 25, 2015 (JST), FastCopy was given Grand Prize in the [Windows Forest Awards](https://en.wikipedia.org/w/index.php?title=Windows_Forest&action=edit&redlink=1) [[ja](https://ja.wikipedia.org/wiki/%E7%AA%93%E3%81%AE%E6%9D%9C)].[8] ## Ported versions - [macOS](/source/MacOS): RapidCopy[9] - [Linux](/source/Linux): RapidCopy for Linux[10] ## See also - [Free and open-source software portal](https://en.wikipedia.org/wiki/Portal:Free_and_open-source_software) - [RichCopy](/source/RichCopy) - [Robocopy](/source/Robocopy) - [Teracopy](/source/Teracopy) - [Ultracopier](/source/Ultracopier) ## References 1. ^ [***a***](#cite_ref-help_1-0) [***b***](#cite_ref-help_1-1) [***c***](#cite_ref-help_1-2) [***d***](#cite_ref-help_1-3) H.Shirouzu (26 June 2022).
