Support paths > 260 characters on Windows

Current builds of Substance Painter 3D on Windows do not support handling paths longer than 260 characters (Windows MAX_PATH limit).

 

Starting with Windows 10, version 1607, MAX_PATH limitation can be lifted. However, this is an opt-in behaviour applications must explicitly subscribe to.

 

https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later

 

Could future builds of Substance Painter 3D implement this new Windows feature, thus removing the limit on paths length?

 

Thank you ⭐

    Hello ​@marta_feriani_scl 

     

    Thank you for the suggestion.

     

    As far as I know, there are currently no discussions on this topic, but I will mention it to the team. Could you tell me what would be your use case?
