Windows has a default max path length of 260 characters. A long file name, particularly when combined with the repository path, may cause this to be exceeded.

Windows 10 (1607) and Windows Server 2016 have a group policy that enables support for path up to ~32,767.

How To

gpedit.msc → Local Computer Policy → Computer Configuration → Administrative Templates → System → Filesystem

Enable "Enable Win32 long paths" or "Enable NTFS long paths" (in older builds).
