Hi,

You are absolutely correct that the Microsoft NTFS filesystem driver requires that the file be significantly less than 1K to be stored in the MFT. The file attributes and metedata need a place to live!

Big Grin | :-D

Edit:
I am the author of multiple filesystem filter drivers. Some of my cryptic statements are a result of having too much experience in this area. My reason for stating <= 1KB is from my experience of saving a 1MB file in 1000 MFT entries. Why do such a dumb thing? For science! (security research)

Best Wishes,
-David Delaune
