NTFS:-> Metadata Compressed or not???

OSR_Community_UserOSR_Community_User Member Posts: 110,217

I just wanted to know if any of u can confirm what all is meant by the fact that 'NTFS Metadata is not in the compressed state on the disk, for a compressed file'.

Metadata here surely refers to the MFT Record Entry of a file, $FILENAME attribute of a file, $STANDARD_INFORMATION attribute & the other attributes. Or is it not?

What about $SECURITY_DESCRIPTOR attribute? If by some rare chance it actually happens to be non-resident & on top of that greater than 16 clusters on disk. Will it be compressed when the file is compressed???

And, what about Named Data attributes?? I personally found that named data attributes of a compressed file turn out to be uncompressed even when greater than 16 clusters in size. Does it meant Named Data is also MetaData????

Thx for ur time & consideration.
