3FS File Extension

Puppy Linux Save State File – file format by Puppy Linux

3FS (Puppy Linux Save State File) is a file extension developed by Puppy Linux used to save the state of a running system, including running programs and open files, allowing users to resume their work later from the exact point where they left off.

What is a 3FS file?

A 3FS file is a Puppy Linux Save State File. It is a compressed file format used by Puppy Linux, a lightweight Linux distribution, to save the current state of the operating system. 3FS files can contain the entire contents of the RAM, including the kernel, drivers, applications, and user data. This allows users to quickly and easily save and restore the state of their system, making it ideal for use on live USB drives or other portable media.

Technical Details of 3FS Files

3FS files are compressed using the SquashFS file system format. This format is designed to be highly efficient, allowing for a significant reduction in file size compared to other compression formats. Additionally, 3FS files are typically encrypted using the AES-256 algorithm, providing an additional layer of security. The file format also includes support for incremental updates, allowing users to save and restore only the changes made since the last save. This further improves performance and reduces the size of the 3FS files.

Opening 3FS Files on Windows

Opening 3FS files on Windows requires a compatible application such as Puppy Linux or a third-party file emulator that supports the 3FS format. You can download Puppy Linux as a bootable ISO image and create a virtual machine or use a live USB to run it without modifying your existing operating system. Once Puppy Linux is running, you can use its file manager to browse and open 3FS files.

Alternatively, you can use a third-party file emulator like 3F Explorer, a lightweight and portable application designed specifically for handling 3FS files within Windows. Download and install 3F Explorer, then right-click on the 3FS file and select “Open With” to associate it with 3F Explorer. You can now access the contents of the 3FS file like any other folder or archive in Windows.

Opening 3FS Files on Linux

Opening 3FS files on Linux is relatively straightforward, as the 3FS format is natively supported by most Linux distributions. You can simply double-click on the 3FS file to launch it using the default file manager or archive manager. Alternatively, you can use the “file-roller” command-line tool to extract the contents of the 3FS file.

To extract the contents using the command line, open a terminal window and navigate to the directory where the 3FS file is located. Enter the following command:


file-roller filename.3fs

Replace “filename.3fs” with the actual name of the 3FS file you want to extract. File Roller will create a directory with the same name as the 3FS file and extract its contents into that directory.

3FS File: Puppy Linux Save State File

A 3FS file is a Puppy Linux Save State File that stores the current state of a running Puppy Linux operating system. It is a compressed file format that contains a snapshot of the entire system, including the kernel, modules, applications, and user data. 3FS files are typically created when the user wants to save the current state of their system for later use, such as after installing new software or making system changes.

3FS files can be used to restore the system to its previous state in the event of a system crash or data loss. They can also be used to create a portable version of Puppy Linux that can be run from a USB drive or other removable media. 3FS files are an important part of the Puppy Linux operating system, providing users with a way to save and restore their system state and create portable versions of the OS.
