IFM
A single-file, web-based file manager built with PHP, JavaScript, and Bootstrap for easy server file management.
What is IFM?
IFM (Improved File Manager) is a web-based file manager that runs as a single PHP file, allowing users to manage server files through a browser interface. It solves the problem of needing command-line or FTP access by providing an intuitive, feature-rich GUI for file operations like editing, uploading, and extracting archives. It's designed to be easy to deploy and use on any PHP-enabled server.
System administrators, web developers, and anyone who needs a simple, browser-based tool to manage files on a web server without relying on SSH or FTP clients.
Developers choose IFM for its single-file deployment, which simplifies installation and updates, and its comprehensive feature set including keyboard shortcuts, LDAP authentication, and Docker support. It offers a balance of power and simplicity without the bloat of larger file management solutions.
Overview
Improved File Manager
Use Cases
Best For
- Managing files on a web server without SSH access
- Quickly editing configuration files via a web interface
- Deploying a lightweight file manager in Docker containers
- Providing a simple file management interface for non-technical users
- Extracting and managing archives directly in the browser
- Setting up a secure, authenticated file manager with LDAP support
Not Ideal For
- Servers without PHP 7.0+ or the required extensions (bz2, curl, ldap, etc.)
- Environments needing granular, role-based access control beyond simple authentication
- Projects requiring real-time collaboration, cloud storage integration, or version control features
Pros & Cons
Pros
Installation is trivial—just drop one PHP file on the server—and updates are equally simple, as highlighted in the Installation section.
Supports editing with ACE Editor syntax highlighting, archive extraction (tar, zip, etc.), and multiple upload methods including remote URLs, per the Features list.
Vim-style navigation (h/j/k/l) and shortcuts for common actions like upload or refresh make it fast for power users, detailed under Keybindings.
Includes a Docker image with environment variable configuration for easy containerized deployment, as shown in the Docker section.
Cons
Default settings lock to the directory, but .htaccess editing is disabled, and production use requires manual tuning of environment variables, which can be error-prone.
Requires several PHP extensions (e.g., bz2, ldap, zip) that may not be pre-installed, increasing setup complexity, as noted in Requirements.
As a single-file project, it lacks plugins, themes, or extensive community support compared to larger file managers, with no mention of extensibility in the README.
