Do you want to know what takes up the most disk space in your phone? Circle File is a tool to analyze the storage (internal or external SD card) in your phone. It enables you to easily find directories and files which consume a lot of space. It counts the size of each directory and provides a summary of every subdirectory and file. There are two possibilities of visualisation. The first is a pie chart and the second is a size bar. You can display detailed information about the selected file. Files can also be shared. It provides an easy way to backup unneeded files (for example, to Google Drive). You can delete files or directories also. For quick access, you can add your favorite directories to bookmarks in Circle File.
