How to Free Up Storage on Android: From Junk Files to Screenshots

Step 1: Clear junk files first (safest)

Junk files are leftovers apps create and abandon, so deleting them costs you nothing. The usual suspects:

• App and ad cache: temporary images and data apps store. They regenerate when needed.
• Logs and temp files: debug records and leftovers from installs and updates.
• Leftover APKs: installer files for apps you've already installed are pure wasted space.
• Empty folders: hollow directories left behind after uninstalling apps.

Step 2: Remove duplicates and similar photos

The same file often lives in two places, and burst shots pile up dozens of near-identical photos. Exact duplicates can be found by comparing file hashes; similar photos can be grouped by scene so you keep only the best shot. Scrolling your gallery by hand is hopeless at scale - an automatic scanner is the realistic option.

Step 3: Clean out screenshots in one sweep

Screenshots are taken "just for a second" but rarely deleted. Shopping pages, chat captures and map snippets quietly add up to gigabytes. Use a tool that gathers the screenshot folder in one view, skim from oldest to newest, and clear them in one pass.

Step 4: Review large and old files

Finally, sort by size. A handful of 100MB+ videos often outweighs thousands of photos. Check the largest files and anything you haven't opened in months, then delete only what you no longer need.
