How do I use the Files app on Android?

Last reviewed: September 21, 2026 · Markdown version

Most Android phones ship with a file manager and most people never open it — usually called Files, or My Files on Samsung. It is the fastest route to "where did that download go", and its three views answer three different questions.

The three views, and when each one is right

Categories (Documents, Images, Video, Audio, Downloads) — built by scanning the whole device, so it finds files wherever the app that saved them put them. This is the right view when you know what you are looking for but not where it is.
Browse / Internal storage — the real folder tree. Use it when you know the path, or when you want to move things rather than open them.
Clean / storage suggestions — Google's Files app surfaces cards here, including one devoted to exactly the pile that fills phones: "Delete downloaded files", with a Select files button and a "Move x file(s) to Trash" action.

Three habits that make it useful

Sort by date, not name. You almost always remember roughly when, and almost never what a downloaded file was called.
Use search with a partial name. It matches file names, so half a word is enough — but it does not look inside documents, which is a different job.
Long-press to select, then move. Multi-select is how you do anything at volume; tapping files one at a time is how people conclude Android file management is hopeless. Moving files properly.

The two things it will not show you

Another app's private storage. Android's rules, not the app's choice: an app "has access only to the app-specific directory on external storage, as well as specific types of media that the app has created." Why that boundary exists.
What is inside your documents. File managers search names, never contents, so "the PDF with the policy number in it" is not a question this tool can answer.

Where Adinand Auto File Sorter fits

A file manager is a place to look; this is a rule that runs so there is less to look through. Pointed at a watched folder — Downloads by default — it files what arrives into Downloads › Sorted Files by category, so the folder stops being a single undifferentiated pile. It only touches files sitting directly in a watched folder, categorises by file extension, and never deletes or overwrites anything.
