Custom file attribute in FAT32 and NTFS

Question

I want the ability add custom property/tag to a file with any file extension. For example file.txt or file.pdf or file.jpg should all store and carry properties like 'custom tag'. The tag should be stored with the file itself. Such that if it is transferred from NTFS file system to usb-disk with FAT32 file system and vice-versa it retains the tag.

How do I make this possible using c++? Any application that already does this?

Thank you

如果您需要同时支持NTFS和FAT32（甚至更多），可以使用扩展属性，请参阅https://en.wikipedia.org/wiki/Extended_file_attributes
