The windows native functions used to deal with the files (ReadFile WriteFile) are limited to write and read bytes defined by a length argument. The length argument is a DWORD and then limited to 0xff ff ff ff .

Images with a size of more than ~4.1GB are not saved properly and cannot be open again.

Fix incoming soon!
