Windows Long Path settings
Windows has traditionally not handled paths which are longer than 260 characters. Any path that is longer than that results in an error. This is a problem for the iconik Storage Gateway as it cannot scan deep structures in a storage which was created on another operating system which supports longer paths, such as MacOS or Linux.
Since Windows 10, Version 1607 Microsoft has removed this limitation as an opt-in setting in the Windows registry. This is a system wide setting which enables this for all applications that support longer paths. The ISG installer now comes with a preference to add this registry setting automatically when the ISG is installed on a new server.
This setting is enabled by default but you can disable it if you are running other software on the ISG server which is incompatible the new MAX_PATH setting. Note however that if you do this, the ISG may not be able to index your entire storage.
