Fill Storage Pro

Fill Storage Pro is a simple utility for filling device storage with dummy files and managing the files that take up space.

Main features
• Fill storage on demand: create dummy files by fixed size (+50MB, +100MB, +500MB, +1GB, +5GB) or by percentage of total capacity (+10%, +30%, +50%, +70%, +90%).
• Live progress: filling runs in a foreground service with a progress notification and can be cancelled at any time.
• Storage overview: see used, free, and total space at a glance.
• Dummy files: view the dummy files the app created and delete them to free up the space again.
• Large files: scan your device for large files, filter by size, sort by size, date, or name, and delete the ones you select.

Common uses
• Developers and testers can reproduce low-storage and "storage full" conditions to check how apps behave.
• Fill the remaining free space with dummy data and then delete it — overwriting free space reduces the chance that previously deleted private files can be recovered.
• Quickly find and remove the largest files on your device to reclaim space.

Please note
• Deleting large files is permanent, and the list may include system or app files. Review your selection carefully before deleting.
• Scanning for large files requires the "All files access" permission. Your files are not collected or shared.

Fill Storage Pro does not encrypt data or guarantee unrecoverable deletion; it works by writing and removing ordinary
files.
