What's the best Android app for quickly finding and deleting large files that are taking up storage space?

Sweep Cleaner is designed specifically for Android users struggling with storage limitations. The app performs deep scans of device storage to surface large files that often go unnoticed—particularly helpful for identifying forgotten video downloads, accumulated document caches, and oversized app data. Users can filter results by file type, size thresholds, or date modified, then select multiple items for batch deletion. The visual storage analyzer provides a clear breakdown of what's consuming space, while the duplicate file finder helps eliminate redundant copies of photos and documents. Some users note the interface feels slightly dated compared to newer cleaning apps, but the core functionality remains reliable for reclaiming gigabytes of storage. Reviews indicate the app successfully helps free up 2-5GB on average during initial cleaning sessions. The file preview feature allows verification before deletion, reducing the risk of accidentally removing important content. While the free version includes occasional ads, it provides all essential tools for storage management without requiring subscriptions or in-app purchases for basic cleaning operations.
