**Notable features removed from the original fork:**

### Directory-Level Access Control
Scoped access rules per user or group.
- ❌ Shell commands are completely removed and will not be returned

### Developer API
- Long-lived API tokens
- Swagger documentation at `/swagger` endpoint
FileBrowser Quantum differs significantly from the original version. Many of these changes required a significant overhaul. Creating a fork was a necessary process to make the program better.

## What's Different from Original FileBrowser
## The User Interface

FileBrowser Quantum is a massive fork with significant changes:
The UI has a simple three-component navigation system:

**Added Features**:
- ✅ Multiple sources support
- ✅ OIDC, password + 2FA, and proxy authentication
- ✅ Beautiful, responsive, customizable UI
- ✅ Simplified configuration via `config.yaml`
- ✅ Ultra-efficient indexing and real-time updates
- ✅ More file type previews (office, video)
- ✅ Highly configurable sharing options
- ✅ Directory-level access control
- ✅ Developer API with long-lived tokens
1. **(Left)** Multi-action button with slide-out panel
2. **(Middle)** The powerful search bar / title
3. **(Right)** The view change toggle / overflow menu

**Removed Features**:
- ❌ Shell commands (completely removed for security)
- :construction: Jobs (not supported yet, planned)
All other functions are moved either into the action menu or pop-up menus. If the action does not depend on context, it will exist in the slide-out action panel. If the action is available based on context, it will show up as a pop-up menu.

## System Requirements

{{% alert context="info" %}}
Every file and directory in the source gets indexed by default. This enables powerful features like instant search, but large filesystems increase memory requirements.
{{% /alert %}}

- **Memory**: Depends on source complexity (typically 256MB minimum)
- **Memory**: 256 MB minimum

Use one memory requirement.

Line 70 states a 256 MB minimum, while Line 94 states a 512 MB minimum for Quantum. These values conflict. Clarify whether 256 MB is an absolute baseline and 512 MB is recommended, or use the same value in both sections.

Also applies to: 94-94

In `@content/en/docs/help/about.md` at line 70, Reconcile the memory requirements
in the Memory section and the Quantum section so they no longer conflict: either
clearly distinguish 256 MB as the absolute baseline and 512 MB as the Quantum
recommendation, or use one consistent value in both entries.

See [How much RAM does it require?](https://github.com/gtsteffaniak/filebrowser/discussions/787) for details.

## The User Interface

The UI has a simple three-component navigation system:

1. **(Left)** Multi-action button with slide-out panel
2. **(Middle)** Powerful search bar
3. **(Right)** View change toggle

All other functions are in the action menu or context pop-up menus.
FileBrowser Quantum uses **SQLite-based indexing** — metadata is stored on disk rather than fully loaded into memory, so large filesystems are much less likely to cause out-of-memory errors than with in-memory indexing. Scan frequency, complexity, and cache settings still affect CPU, I/O, and typical memory use. See {{< doclink path="features/indexing/" text="Indexing Overview" />}} for scan strategies, performance expectations, and configuration.

## Current Status

{{% alert context="warning" %}}

Name the stable release.

Line 77 says v2.0.0 is in beta, but Line 78 says stable releases are available without identifying their version. Readers cannot determine whether the stable channel is v1.x or whether v2.0.0 has a stable build. State the stable version or channel explicitly.

🌐 Web query:

site:github.com/gtsteffaniak/filebrowser "Comparison Chart" "Docker image size"

💡 Result:

There is no universal comparison chart for Docker image sizes because sizes are highly dependent on the software stack, language runtime, and libraries included in a specific image. However, Docker image base sizes generally follow a hierarchy based on the underlying distribution and packages they contain. Typical Base Image Size Hierarchy: 1. Scratch: An empty image (0 MB) used as a starting point for static binaries or language runtimes that do not require an operating system. 2. Alpine: A minimal Linux distribution (typically 5 MB) often used to keep images small while still providing a package manager (apk). 3. Slim variants (e.g., Debian Slim): Stripped-down versions of common distributions (typically 20-50 MB) that exclude non-essential files to reduce the attack surface and size. 4. Full distributions (e.g., Debian, Ubuntu): Standard images (often 70 MB+) containing essential system tools and libraries, providing high compatibility but larger footprints. Optimization Best Practices: To minimize your Docker image size, follow these official best practices: Use Multi-Stage Builds: This allows you to compile your application in a heavy build environment and copy only the final artifacts (binaries, static files) into a much smaller production image. Example: FROM golang:1.21 AS builder WORKDIR /app COPY.. RUN go build -o myapp FROM alpine:latest COPY --from=builder /app/myapp /myapp CMD ["/myapp"] Minimize Layers: Combine related commands into a single RUN instruction using && and cleaning up artifacts (e.g., package manager caches) within the same layer to avoid keeping unnecessary data in the image history. Use.dockerignore: Prevent unnecessary files, such as local git repositories, build caches, or documentation, from being copied into the image context. Select the Right Base Image: Use the smallest base image that meets your application's requirements. If you only need a binary, prefer scratch or alpine. If you require glibc or specific Debian-based libraries, use the slim variants.

Synchronize the comparison table with the upstream README.

The linked README qualifies the image sizes as 180 MB (with ffmpeg) and 240 MB (main image), and the Filestash memory value as 128 MB (main image). The page omits these qualifiers. Copy the README values or keep one canonical table to prevent drift.
