Hi there,
How do I lock files to make them undeletable at the file level? I saw another protection app do this (something with NTFS?)

Thanks for any pointers!

FileSetAttr('MyFile.sys', faReadOnly or faSysFile);

FileSetAttr returns zero if the function was successful. Otherwise the return value is a Windows error code.

var
 Attributes: Integer;
begin
 //can't delete
 Attributes:= Attributes and faReadOnly or faSysFile;
 FileSetAttr('c:\test.exe ', Attributes);
 //can delete
 Attributes:= Attributes and not faReadOnly or faSysFile;
 FileSetAttr('c:\test.exe ', Attributes);
end;

Yes! - This is basic File manipulation stuff. Did you test it?
