Recovery: the information about the deleted file (name, size, location) remains in the MFT. This article (I have nothing to do with the author or the site/org) which compares the recovery prospects (emphasis mine). (This answer is an expansion to my comment on this answer which talks about Journaling in NTFS.) I think this is the second biggest difference after "compatibility with other OSes".įrom a Recovery point of view NTFS appears to be better suited. If you don't use EFS (like almost everybody, ever) then obviously this doesn't apply. Edit see comment, apparently this isn't true in Win10. Any files you copy to it will then get decrypted automatically, on the fly. If you do this often, choose exFAT on the removable drive. If you forget to manually decrypt it, you won't be able to access it on the other machine. However, if you usually take files to machines that don't have the decryption certificates, there is no way to tell Windows to automatically decrypt a file when it's copied to an external disk. Then your files stay encrypted in transit, yet are transparently accessible on all authorized computers. This can be great, and this can also be incredibly annoying, depending on your use case.īasically, if you want to take your files to another computer that has all the same decryption certificates installed, choose NTFS on the removable drive. When you copy an encrypted file to another NTFS volume, it stays encrypted using the same key(s) the original was. Files are encrypted on the disk, but are automatically decrypted when you access them. One very important difference comes about if you use the EFS "Encrypted" attribute (EFS stands for Encrypting File System, which is not actually a file system, but rather a feature of NTFS). Of course, only if your definition of “ideal” allows software to be proprietary and not open source. exFAT’s smaller footprint/overhead makes it ideal for this purpose. NTFS on flash memory has been known to be inefficient for quite some time. However, exFAT should be a true competitor to NTFS on systems with limited processing power and memory. This is likely more aimed at digital video recorder type devices, home users get a licence to use it with Windows. The only drawbacks to exFAT are that Microsoft has not released it into the public, requiring that companies licence it for use on their devices. Some of the missing (and effectively useless or a waste for removable media) features include: In theory, exFAT does not have as much of the operational overhead of NTFS as it lacks many features that add complexity (and therefore processing time and disk latency) to the filesystems. What Microsoft developers have basically done is update the FAT32 file system to exFAT, moving from 32-bit addressing to 64-bit addressing, to offer an improved speed alternative over moving to NTFS at the same time making it possible to create, store or transfer huge files, files greater than 4GiB. Provision for OEM-definable parameters to customize the file system for specific device characteristics (for use in embedded devices with specific needs).Support for access control lists (so you can control file access if you want but I suspect the main use would be for USB devices where you just want people to access it go figure.).Free space allocation and delete performance improved due to introduction of a free space bitmap (much better performance than FAT32).File size limit of 16 EiB (Limited by volume size), raised from close to 4 GiB in FAT32 (Better support for video editing and large archives).Cluster size up to 32 MiB (allowing for larger partitions at the cost of more file slack).Note that the built-in Windows 2000/XP/Vista/7 can mount and support FAT32 volumes larger than 32 GB, but cannot create a FAT32 volume larger than 32 GB. Scalability to large disk sizes: 64 ZiB theoretical max, 512 TiB recommended max, raised from the 16 TiB limit of FAT32 partitions.There are some people working on Linux exFAT support, but I can't tell how far along they are, and as always, there is a risk of corrupting your data just like with NTFS. One of the key features for people doing video editing is the support for >4GiB files and much larger partition sizes than FAT32 typically supported, making it much easier to work with modern multi-terabyte drives.ĮxFAT is available for Windows Vista, 7, and I believe I may have even seen a Microsoft release to make XP work with exFAT. ExFAT basically takes the FAT file system to the next level, adding a large amount of long awaited features that the FAT32 system was sorely lacking.
