Can someone please tell us/me if the MAX_PATH issue still exists in (the technical preview of) Windows 10. And if it exists: How many characters can a path and an individual file name have?
825
Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem. Double click Enable NTFS long paths. Select Enabled, then click OK.
In editions of Windows before Windows 10 version 1607, the maximum length for a path is MAX_PATH, which is defined as 260 characters. In later versions of Windows, changing a registry key or using the Group Policy tool is required to remove the limit.
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.
The issue will be always present in Windows, to keep compatibility with old software. Use the NT-style name syntax "\\?\D:\very long path" to workaround this issue.
In Windows 10 (Version 1607 - Anniversary Update) and Windows Server 2016 you seem to have an option to ignore the MAX_PATH issue by overriding a group policy entry enable NTFS long paths under Computer Configuration -> Admin Templates -> System -> FileSystem:
The applications must have an entry longPathAware similar to DPIAware in the application manifest.
