Steam Sweeper

SteamSweeper

is a Windows utility designed to scan Steam library folders and identify leftover data from uninstalled or incomplete game installations.

Over time, Steam libraries can accumulate residual files and folders that are no longer associated with installed games. These can include partial installations, leftover assets, or orphaned files that remain after uninstalling games.

SteamSweeper analyzes the active Steam library structure and helps you locate these remnants so you can safely review and clean them up.

Key Features

• Automatically detects Steam installation
• Manual Steam library path selection (advanced option)
• Scans Steam libraries for leftover files and orphaned game data
• Ignores Steam system and shared folders automatically
• Folder/file exclusion list for fine-grained control
• Built-in logging system (in-app + log files)

Safety Design

SteamSweeper is built with safety in mind:

• System drives and critical directories are blocked (C:, Windows, ProgramData, Users)
• Steam system folders are excluded by default
• No permanent deletion without explicit user confirmation
• Backup system is used for all cleanup operations
• Full logging for transparency and traceability

How It Works

SteamSweeper uses your active Steam installation and library paths to scan common Steam structures such as steamapps/common and related directories.

It identifies leftover or orphaned data that no longer matches active installations, allowing you to review and clean up unnecessary disk usage.

Requirements

• Windows OS

Note

SteamSweeper is intended as a maintenance tool for occasional cleanup of Steam library leftovers. It performs real file operations, so reviewing detected items before removal is strongly recommended.
