![]() ![]() If any of these characters are used, unexpected results may occur. The name must start with either a letter or number and can contain any characters except for the following: The name of a file or directory can be up to eight characters long, then a period (.) separator, and up to a three character extension. FAT naming conventionįAT uses the traditional 8.3 file naming convention and all filenames must be created with the ASCII character set. ![]() ![]() ![]() In addition, FAT supports only read-only, hidden, system, and archive file attributes. There is no organization to the FAT directory structure, and files are given the first open location on the drive. It is time consuming because the disk read heads must be repositioned to the drive's logical track zero each time the FAT table is updated. If the FAT table is not regularly updated, it can lead to data loss. Updating the FAT table is very important as well as time consuming. This entry in the FAT table either indicates that this is the last cluster of the file, or points to the next cluster. When a file is created, an entry is created in the directory and the first cluster number containing data is established. In addition, the FAT tables and the root directory must be stored in a fixed location so that the system's boot files can be correctly located.Ī disk formatted with FAT is allocated in clusters, whose size is determined by the size of the volume. To protect the volume, two copies of the FAT are kept in case one becomes damaged. The FAT file system is characterized by the file allocation table (FAT), which is really a table that resides at the very "top" of the volume. FAT overviewįAT is by far the most simplistic of the file systems supported by Windows NT. Also, support for the FAT32 file system became available in Windows 98/Windows 95 OSR2 and Windows 2000. Windows NT 4.0 does not support and cannot access HPFS partitions. Torvalds suggests Paragon do future merges from the command-line.HPFS is only supported under Windows NT versions 3.1, 3.5, and 3.51. 'For GitHub accounts (or really, anything but where I can just trust the account management), I really want the pull request to be a signed tag, not just a plain branch,' Torvalds explains. As Torvalds points out, this is particularly important for new contributors to the Linux kernel. Torvalds also had some pertinent security advice, perhaps useful in light of recent software supply chain cyberattacks that the Linux Foundation wants to address by improving supply chain integrity through tools that make it easier to sign software cryptographically. For instance, GitHub's commit message for Paragon's merge read 'Merge branch 'torvalds:master' into master', which didn't impress Torvalds one bit. One of the shortcomings Torvalds highlighted are GitHub's concise, factually correct, but functionally useless, commit messages. Torvalds' chief problem with it was that merges need 'proper commit messages with information about is being merged and *why* you merge something.' He continued: 'But it also means proper authorship and committer information etc. He continued: 'That's another of those things that I *really* don't want to see - GitHub creates absolutely useless garbage merges, and you should never ever use the GitHub interfaces to merge anything.GitHub is a perfectly fine hosting site, and it does a number of other things well too, but merges are not one of those things.' 'I notice that you have a GitHub merge commit in there,' wrote Torvalds. 'But he also had some process and security lessons to offer developers about how to code submissions to the kernel should be made.' 'Linux creator Linus Torvalds has agreed to include Paragon Software's NTFS3 kernel driver, giving the Linux kernel 5.15 release improved support for Microsoft's NTFS file system.' reports ZDNet, adding that the driver 'will make working with Windows' NTFS drives in Linux an easier task - ending decades of difficulties with Microsoft's proprietary file system that succeeded FAT.' ![]()
