If you're really determined, the [NTFS file-stream] format looks as follows:
Windows Terminal
Given a rating of "5 stars" and a tags of "touched"
afm .%H(fs-read('.default.md:\x07OpusMetaInformation'),,16)
1400000000000000
6300000000000000
0900000074006F00
7500630068006500
640000000000
The rating is at offset 16 => "63"
63~00000000000000~
The tags => "touched" is a UNICODE string whose UInt32 (DWORD) length starts at offset 32
09000000~7400~6F00~7500~6300~6800~6500~6400~0000~0000
length 9-chars, 0x74, 0x75, 0x63, 0x68, 0x65, 0x64, 0, 0
E.g.,
afm .(`$:%H('touched\x00\x00') length: $:sizeof('touched\x00\x00')`)
746F75636865640000 length: 9
- Windows Summary Information Stream
- Description of that stream
afm .%H(fs-read('.default.md:\x05SummaryInformation'),,16)
Will get you access to the comments, but it is a bit more complicated to decode. Hint: The comments are at the end typically if no other fields.
You can see [xattr] file streams on an NTFS-File by typing dir /R at a console [wt.exe or cmd.exe] command-line.
