WinAPI CreateFileA error code 0xdf

I have a mapped Webdav Drive and i can't open file for reading using 

CreateFileA(file_path, FILE_READ_DATA, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

i am still getting error code 0xdf

ERROR_FILE_TOO_LARGE 223 (0xDF) The file size exceeds the limit allowed and cannot be saved.

but on diskdrive (NTFS) i can read it, but on mapped drive represents as (FAT) a i can just write file 

CreateFileA(dest_file_path, FILE_WRITE_DATA, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);

it works

but not reading not, when the file size exceed for example 70 MB

my webdav is running on apache.

can anyone help me?

Solution

  • SOLVED

    That was a probliem with WebClient Service paramater FileSizeLimitInBytes

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes

    that was set to 50,000,000 Bytes 50MB

    If i set it to

    0xffffffff

    is now possible handle with 4GB files.
