How to encrypt external drive with Bitlocker in macOS?
Because Microsoft disagreed with IBM on many important issues they eventually separated: Using the same Partition ID Record Number is highly unusual, since there were dozens of unused code numbers available, and other major file systems have their own codes.
Released with Windows NT 3. Volumes written by Windows NT 3. Supports compressed files, named streams and access control lists. Released with Windows NT 4. Commonly called NTFS 4. Released with Windows ;  compatibility was also made available for Windows NT 4.
Reorganized security descriptors so that multiple files using the same security setting can share the same descriptor. Commonly called NTFS 5. Features[ edit ] NTFS v3.
It is a feature that FAT does not provide and critical for NTFS to ensure that its complex internal data structures will remain consistent in case of system crashes or data moves performed by the defragmentation API, and allow easy rollback of uncommitted changes to these critical data structures when the volume is remounted.
Notably affected structures are the volume allocation bitmap, modifications to MFT records such as moves of some variable-length attributes stored in MFT records and attribute lists, and indices for directories and security descriptors. The journal is made available for applications to track changes to the volume.
Hard links are similar to directory junctionsbut refer to files instead. Hard links may link only to files in the same volume, because each volume has its own MFT.
Hard links have their own file metadata, so a change in file size or attributes under one hard link may not update the others until they are opened. Operating system support is needed because there are legacy applications that can work only with 8. In this case, an additional filename record and directory entry is added, but both 8.
The NTFS file system has a limit of hard links on a file. Fork file system Alternate data streams allow more than one data stream to be associated with a filename a forkusing the format "filename: Very small ADS named "Zone.
Identifier" are added by Internet Explorer and recently by other browsers to mark files downloaded from external sites as possibly unsafe to run; the local shell would then require user confirmation before opening them. Alternate streams are not listed in Windows Explorer, and their size is not included in the file's size.
When the file is copied or moved to another file system without ADS support the user is warned that alternate data streams cannot be preserved. No such warning is typically provided if the file is attached to an e-mail, or uploaded to a website. Thus, using alternate streams for critical data may cause problems.
Microsoft provides a tool called Streams  to view streams on a selected volume. Starting with Windows PowerShell 3.
This allows for reasonable random-access times as the OS just has to follow the chain of fragments. The following section refers to tests, research and recommendations done and intended for storage devices with a high Access timesuch as a mechanical HDD, where the internal heads used for reading data, needs to be physically moved and positioned correctly, and then wait for the data on the rotating disks to pass beneath them.
See further down for updated info regarding SSD and similar devices with low Access time. This reasonable maximum size decreases sharply for volumes with smaller cluster sizes. Users of fast multi-core processors will find improvements in application speed by compressing their applications and data as well as a reduction in space used.
Compression works best with files that have repetitive content, are seldom written, are usually accessed sequentially, and are not themselves compressed. Log files are an ideal example. Files may be compressed or decompressed individually via changing the advanced attributes for a drive, directory, or directory tree, becoming a default for the files inside.
Empty bytes don't need to be saved, thus they can be represented by metadata. Sparse files are files interspersed with empty segments for which no actual storage space is used.
To the applications, the file looks like an ordinary file with empty regions seen as regions filled with zeros.Full read/write access to NTFS and HFS+ volumes!
