- nullindividual 2y agoThe MFT describes resident (in-MFT) metadata about files, or non-resident (external to the MFT, but the MFT has a pointer) if the metadata does not fit within the MFT. The MFT itself is a database; Windows makes use of file system caching, be it in-memory or another caching mechanism, like on-device disk cache.
