Usable File System
Template:File systemThe Usable File System (ufs), is a simple, Open source, filesystem developed by Xeno333. It was originally published on the osdev.org forum[1]. It was created to be a simple filesystem for use by OS developers, back in 2022 but was not released until 2024[1]. The full specification was put on GitHub[2], Medium[3] and on Xeno333's publishing site hosted on Tor at the tor address: lk7bjcs33czqkalf6b2xwo73rhtivrstc6wasjrtjpsuihzoucp7ljad.onion/pdfs/UFS_v1.0_Spec.pdf
The author has chosen to call it ufs (lowercase) as not to conflict with the Unix File System[1]. It was published and licensed under the MIT license[2][1]
The ufs v1 filesystem is designed to be a simple filesystem, yet more capable than FAT, with 64 bit block representation, instead of FAT32's limit of 28 bit.
Versions
As of this writing there is only one version of ufs, but the developer did imply there may be future improvements, such as journaling.[1]

Data Structures
