Maximum Path Length Limitation
In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters . A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character .

Remove the Max Path Length Limit (260
Windows has a well-known limitation that restricts the maximum length of a file or folder path to 260 characters . File Explorer and many Win32 apps cannot handle file paths longer than 260 characters .
Windows 95 abandoned that to allow long file names, but still limited the maximum path length (which includes the full folder path and the file name) to 260 characters . That limit has been in place ever since.
What are the file path length limits
What are the path length limits across platforms? The following table summarizes the maximum file path length for each platform. The most restrictive limit you encounter in everyday use is 260 characters on Windows File Explorer and Office desktop apps.
The path length limitation in Windows operating systems can be traced back to the early DOS era. In the Windows API, the maximum path length is defined as the MAX_PATH constant, with a value of 260 characters .
Daily Challenge
Modern versions of Windows ( Windows 10 version 1607 and later, including Windows 11) can support longer paths , up to about 32,767 characters ( the Win32 extended‑length path limit ), if long path support is enabled via Group Policy or the registry, and the application being used supports extended- length paths . Practical fixes include:
MAX_PATH=260 is a Win32 API limit covering " D:\ + up to 256 characters + the terminating NUL," while NTFS itself can handle extended- length paths of roughly 32,767 characters .
