Hello,
I have a question: is it possible to access and change (adding keys) file metadata information presented in Details tab. It's my file written using TFileStream. I have to write one additional string and do not want to change binary record structure to be compatible with previous versions. Is it possible for Windows 7 and higher? 

Thanks in advance, Fred

You have to access the file's Property Set that contains the Summary fields:
