# Windows Long Path Support

Support for long paths (paths that exceed **260 characters**) on Windows is limited. Errors may be encountered in a variety of tools such as CMake when building a project or even Git when cloning a new repository.

## Enable Long Paths

Long paths may be enabled in Windows using the following [guide](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). For more information, please consult the official [Microsoft documentation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry).

However, this setting may not fix all scenarios that may be encounered in the MCUXpresso for VS Code workflow.

## Known limitations

### ARM GCC
 ARM GCC does not support long paths on Windows. In order to successfully build a project, it may be necessary to limit the project's folder structure to a shorter length. The build system usually generates directories with long names, so it would be advisable to keep the base project path as short as possible.
