All programs store files in your phone's internal memory (so called memory cache). Normally, those files can be necessary, however they can also lead to various issues.
1. Cache of deleted files being stored after an app is removed (you need to find and clean the phone from unused cache files).
2. Excessive space being used on you flash memory (you need to clean your storage and empty more space).
3. Private files are stored without you knowledge.
For instance, many of your photos may be stored in the phone's memory even after you removed them. This what messengers and social networking apps do. We find and let you remove those media files, or otherwise restore deleted files from cache.
Please note: that restoring files from cache does not guarantee that you will get the same quality as was in the original files.
So yes, to put it simply, Refile helps you find hidden content on your phone and remove it. After scanning your phone, it shows suspicious folders on your phone. So you can choose which files to keep an eye on.
We never access you files or send them elsewhere. We believe you data must be yours. The app only removes you files when you tell it to do so.
Feel free to ask questions when leaving reviews.
