In CopyFileEx, and DeleteFile functions, by default, the file name and path are limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, need prepend "\\?\" to the path.
Starting in Windows 10, version 1607, MAX_PATH limitations have been removed from many common Win32 file and directory functions. However, your app must opt-in to the new behavior.
To enable the new long path behavior per application, two conditions must be met. A registry value must be set, and the application manifest must include the longPathAware element. --- dlls/kernel32/tests/file.c | 268 +++++++++++++++++++++++++ dlls/kernel32/tests/wine_test.manifest | 9 +- 2 files changed, 275 insertions(+), 2 deletions(-)
