Windows cannot find C:\Program Files

Windows has a default maximum path length of 260 characters (MAX_PATH), which causes CANNOT FIND PATH when tools create deeply nested directories or long file names. This limit was introduced with Windows NT and persists for backward compatibility even in Windows 11. Deep node_modules trees, Maven local repositories, and Android build artifacts are the most common victims of the MAX_PATH limit. The symptoms: cryptic file-not-found or access errors when the actual issue is path length. Fix: enable long path support in Windows 10 version 1607+ by setting the Group Policy "Enable Win32 long paths" or the registry key HKLMSYSTEMCurrentControlSetControlFileSystemLongPathsEnabled = 1. Applications must also opt in by setting longPathAware in their manifest. For Git, run git config --global core.longpaths true. For npm, ensure the registry long paths setting is enabled with npm config set long-path true. Moving projects to short paths like C:p instead of deeply nested OneDrive or Documents folders also resolves most long-path CANNOT FIND PATH occurrences.
