Types of Junk Files on Android Phones

Thankfully, there are several apps that work to quickly remove all the junk on your phone. But that doesn’t mean all trash can be deleted with one tap, because of course there are junk files that can only be deleted independently.

In this article, we will share a list or various types of junk files commonly found on Android phones. You can study and delete it if you find a trash similar to the list below.

Some Types of Junk Files on Android

1. App Cache Files

The main thing, of course, is the cache file on all installed applications. By default, the cache will be cleared automatically at the time set by the application, and usually 1 week.

But too much cache will make it continue to accumulate, so this will have an impact on drained storage. For example like Instagram which will cache the recently watched video files. If many videos are watched, of course the cache size will continue to increase.

2. Unused Folders

This refers more to the leftover folder of applications that have been uninstalled, thus rendering them obsolete. Sometimes the cleaning app still can’t detect this kind of thing, so the user has to uninstall it independently.

An example is a game Minecraft PE, where when you delete the game, the rest of the folders on both internal and external storage will still be there. Even if it contains files like save game, but still it belongs to the category of trash from unused folders.

3. Empty Folder

Unlike the unused folders, this empty folder is usually created by the phone owner himself. Most make a lot of it just to hide a secret file which is really useless for now.

Why is it useless? Because there are many applications protector against former privacy. Even on mobile Samsung Secure Folder feature is available to keep all files and applications from the public.

An empty folder that you created may not have a size up 1 Kilo Byte, but with so many empty folders, it will only make loading in the file manager a little longer than usual.

4. Hidden Files and Folders

On Android, you can make a file or folder hidden by the default file manager application simply by adding a period symbol to the prefix of the file or folder name. And sometimes an application also applies this to their additional data.

Overall this is almost the same as an unused folder, because the hidden folder or file will settle on the phone even though the application has been deleted. And the solution is to check manually with a file manager application advanced as X-plore or ES File Manager.

5. LOST.DIR Folder folder

Not sure if this LOST.DIR folder is still in use today. But on Android OS Kitkat and below it still applies the folder when there is a file that is suddenly deleted by the system.

So if your file, such as an image or video, is missing, it could be in the LOST.DIR folder. And the size of the folder can be large depending on the number of files lost due to system errors.

6. Gallery Trash

Deleted photos or videos are sometimes not actually deleted and will be moved to the trash. The trash feature in the Gallery is widely available on all mobile phones now. In fact, this feature helps to restore content that was accidentally deleted.

It’s just that sometimes cellphones need a lot of storage space when they want to record video. So if your phone storage is drained, please also check the trash in the Gallery, maybe there are dozens of discarded videos that are still stored there.

7. Browser Storage

When browsing a website, our cellphones unconsciously carry some additional data that is loaded on the browser. The data is a file cache and cookies. It does not affect the performance of the phone, but has a significant effect on the storage of the phone.

Storage on the browser can be set via Application Settings. There is usually given the option to delete some things like cache, cookies. browsing history, and more.

8. Former Download Files

Surely you’ve downloaded files on the internet right? Be it documents, applications, images, or videos. Sometimes we forget if the downloaded file is no longer important to have. An example is the application file (APK).

The application file is only used once and once the application is installed, of course it becomes useless. But most cleaning apps will usually display a notification to delete the APK file after the installation process is complete.

9. Images and Videos from Chat Apps

Some chat applications, for example WhatsApp will save image and video files in a special folder. It will still be saved and can be directly managed via Gallery.

If there are a lot of files stored, it will definitely result in wasted storage space. For that, if the images or videos contained in the rest of the chat are no longer useful, it’s better to delete them so that they can free up cellphone storage space.

10. Saved Clipboard

The clipboard feature is mostly available on keyboard apps on Android. But in some phones also have the Clipboard feature directly from the system, such as on the Samsung Galaxy Note phone.

Although overall it’s just a copy of a text and an image, but still it can be called trash if you don’t need it in the future. But even if you don’t delete it, it won’t have a big impact on storage. Because the clipboard takes up very little space.

There are 10 types of Android trash that have been shared above. Maybe there are many types other than the above. And if you know of it, please share it in the comments to help inform other users.
