File Cleaner is a free utility and tool application developed by fmroid for Android devices. With this application, users can delete files in a specific folder with just one touch. It can delete everything in the specified folder, including subfolders. The default setting is a path in which a screenshot is saved, but users can choose the folder they want to delete.

It is important to note that the path is from /sdcard/, and depending on the device model, /sdcard/ can show the internal storage or the SD card in /sdcard/external_sd/. Also, it is not possible to delete files in the SD card when using Android 4.4 due to the limited specifications for writing to the SD card. Therefore, users should not specify the path to the SD card. Before using the application, users must ensure that storage permission is turned on, or it may not work correctly.
