Introducing Archivefs: A Fast and Convenient FUSE Filesystem for Mounting Compressed Archives

Are you tired of having to extract files from compressed archives before accessing them? Do you often find yourself searching for specific files amidst a sea of archived content? If so, then Archivefs is the perfect solution for you. Archivefs is a read-only FUSE (Filesystem in Userspace) filesystem that allows you to seamlessly mount compressed archives and access their contents as if they were regular directories. Inspired by archivemount, Archivefs offers numerous features and performance enhancements that make it an invaluable tool for managing and working with compressed archives.

What is Archivefs?

Archivefs is a FUSE filesystem designed to efficiently mount and access files within compressed archive formats. With Archivefs, you can mount any archive file supported by the libarchive library to a directory, eliminating the need to extract the entire archive to disk. By providing read-only access to the contents of the archive, Archivefs ensures that the original files remain intact, preventing accidental modifications.

Fast Decompression for Enhanced Performance

One of the standout features of Archivefs is its significantly faster decompression speed compared to other solutions like archivemount. Thanks to optimized algorithms and efficient resource utilization, Archivefs provides several orders of magnitude faster decompression. This means you can access the files within the mounted archive with minimal latency, improving overall productivity and reducing waiting times.

Extensive Format Support

Archivefs supports a wide range of archive formats, including but not limited to the following:

  • Tar (compressed with gzip, bzip2, xz, zstd)
  • Cpio
  • ISO9660 (including Joliet and Rockridge extensions)
  • Zip
  • 7-Zip

Please note that while Archivefs supports reading from rar archives, there may be some limitations due to known bugs in the underlying libarchive library.

Seamless Integration and System Requirements

To install and run Archivefs, you’ll need the following:

  • Linux Kernel 3.15 or later (support for other operating systems is currently limited)
  • The fusermount command (typically provided by the fuse or fuse2 package)
  • The libarchive library

For compiling Archivefs from source, you’ll need:

  • Rust 1.31 or later
  • Development files for libarchive (e.g., libarchive-dev or libarchive-devel package)

If you’d like to build the man page for Archivefs, you’ll also need:

  • Python 3.5 or later
  • AsciiDoc

Archivefs is designed to seamlessly integrate with your workflow, providing a user-friendly experience for working with compressed archives.

Simple and Straightforward Usage

Using Archivefs is straightforward. After installation, you can mount an archive file by running the following command:

archivefs [OPTIONS] ARCHIVEPATH MOUNTPOINT

For example, let’s consider a gzipped tar archive named files.tgz containing files file1 and file2, along with an empty directory named mnt.

To mount the archive file, simply run the command:

$ archivefs files.tgz mnt

Once mounted, you can access the contents of the archive as if they were regular files and directories. For instance, you can list the files within the mounted archive:

$ ls mnt
file1 file2

Performing read operations on the archive via the mount point is as simple as working with any other directory. For example, you can copy a file from the archive to your home directory using the cp command:

$ cp mnt/file1 ~/

When you’re done working with the archive, you can unmount it using the umount command:

$ umount mnt

Please note that Archivefs only supports reading from archives and does not provide write support like archivemount.

Special Considerations for Hard Links

If the archive you mount contains hard links, Archivefs will treat them as separate files. This behavior ensures that each hard link is accessible as an individual entity when browsing the mounted archive.

A Game-Changer for Compressed Archives

Archivefs fills a critical gap in the realm of compressed archive management by offering a convenient and efficient solution for accessing files without the need for extraction. Whether you’re a developer searching for specific files within an archive, a data scientist exploring datasets, or a system administrator managing large collections of compressed files, Archivefs will revolutionize how you work with archives.

With its impressive performance, extensive format support, and simple usage, Archivefs empowers users to navigate and access the contents of compressed archives effortlessly.

Future Improvements and Feedback

As Archivefs continues to evolve, user feedback and testing play a crucial role in shaping its development. The development team actively seeks user insights to refine the product based on real-world use cases and requirements. This commitment to continuous improvement ensures that Archivefs remains the go-to solution for compressed archive management.

Roadmap for the Future

Looking ahead, the Archivefs team has some exciting plans for enhancements and new features. Future updates aim to improve performance and compatibility, introduce support for additional archive formats, and provide more advanced functionalities for managing and interacting with mounted archives. Stay tuned for upcoming releases to experience the latest advancements in compressed archive management.

Summary

Archivefs is a game-changer for anyone working with compressed archive files. With its read-only FUSE filesystem capabilities, lightning-fast decompression speed, and support for a wide range of archive formats, Archivefs simplifies the process of accessing files within archives. By bridging the gap between archived content and the everyday workflow, Archivefs empowers users to work more efficiently while reducing the time and effort required to manage and extract files.

Step into the future of compressed archive management with Archivefs, and embark on a seamless journey of enhanced productivity and streamlined file access.
