Welcome, Retro Enthusiast! (A Simple Guide to ADF Files)

For anyone who remembers the golden age of 16-bit computing, the Commodore Amiga holds a legendary status. It was a machine that was years ahead of its time, and its spirit is kept alive today through emulation. The most common way to preserve and share classic Amiga software is with an **.ADF (Amiga Disk File)**. Think of an ADF as a perfect, digital snapshot of a real 3.5-inch floppy disk. It's a complete, byte-for-byte copy that preserves not just the files, but the entire disk structure, including its name and file system. This is what allows Amiga emulators to read them as if they were real, physical disks.

But what if you just want to quickly see what's on an ADF file without the hassle of configuring and launching a full emulator? That's exactly what this tool is for. It's a lightweight, modern, and completely browser-based utility that acts like a digital X-ray for your ADF files. You can drag and drop a disk image, and it will instantly parse the AmigaDOS filesystem within it. There's no software to install and no complex setup. It immediately shows you the disk's volume name, what kind of file system it uses, and a clear, easy-to-read list of all the files and folders it contains. It's the fastest and safest way to explore your collection of classic Amiga treasures.

How to Use The Analyzer

Exploring your digital disk collection couldn't be easier:

1. Select Your File: Drag and drop any standard 880KB Amiga Disk File (.ADF) onto the designated area, or click the link to browse for the file on your device.
2. See the Results Instantly: The moment you select a file, the tool will read and parse it right in your browser. The results panel will appear, showing you a complete breakdown. Your results are automatically saved for your next visit!
3. Examine the Details: In the "Disk Information" panel, you can see the disk's volume name and a visual representation of its used and free space. In the "File Contents" panel, you'll find a tree view of all the files and folders on the disk.
4. Analyze Another: When you're ready to check another disk, just click the "Analyze Another Disk" button to return to the upload screen.

Tips for Amiga Aficionados

• Standard Disks Only:** This tool is specifically designed for standard AmigaDOS-formatted 880KB double-density disks, which is the most common format for shared software. It may not be able to read custom, non-DOS formatted disks (which were often used for games with copy protection) or high-density 1.76MB disk images.
• OFS vs. FFS:** The Amiga had two main file systems that you'll encounter. The **Original File System (OFS)** was the classic standard used in the early days. The **Fast File System (FFS)** was a later improvement that allowed for faster file access, longer filenames, and subdirectories. This tool will automatically detect and tell you which one your disk uses.
• What are `.info` files?:** As you browse disks, you'll almost always see a `.info` file for every other file and folder. These were a brilliant part of the Amiga's operating system! They are tiny files that store metadata about an icon, such as what it looks like and where it's positioned on the Workbench screen. Seeing them is a normal and essential part of an authentic Amiga file structure.
• Complete Privacy:** All the file processing happens directly on your computer, right inside this browser tab. Your files are never uploaded to any server, ever. This ensures your data remains completely private and secure.
