Time needed: 9 minutes.

Any electronic device which stores data can gather so much data that it starts to hang and a laggy smartphone is something that every person hates. Eventually, you run out of storage space for your photos and music, or that you cannot install any more useful apps irrespective of the storage capacity of your phone. So here is a list of 10 ways you can follow on how to delete hidden files on an android phone in less than 2 minutes.

  1. Clear Cached Data

    As you use an app more and more it creates cache files which is a kind of junk file that takes up a lot of storage space. Depending on much you use that particular app, the size of cached files gets bigger and bigger.
    There is another type of cached data that is stored by your phone (in general) and not by your app.
    Well, you can easily delete these files without comprising your app data or android data.

    How to delete cached data of android apps?

    1.) Open your Settings app and head over Apps.
    2.) Tap on any app and click on the Storage option.
    3.) Now hit the Clear data option to delete the cached data.

    How to delete cached data inside storage?

    1.) Open the Settings app.
    2.) Choose the Storage option and now scroll down to the Cached data option.
    3.) Now click on the cached data option to delete the cached data storage.
    This method will help you free up a lot of internal storage on your phone and delete junk files without using any third-party app.

  2. Clean Downloads folder

    Every android phone has a downloads folder where whatever you download from the internet is stored.
    The downloads folder is one of the folders which consumes a lot of storage because whenever we have to download any media or apk from the internet we simply download it use it and forget about it.
    This way it stacks up a lot of data which eventually slows down our mobile phones.
    To delete the junk files in the Downloads folder go to:
    1.) Open your file explorer/manager.
    2.) Go to Internal storage and choose the Download folder.
    Now go through a list of all the apks and media and delete all the unwanted files and folders.
    The data stored in the Downloads folder is a kind of hidden data that goes unnoticed a lot of times.

  3. Delete Photos & Videos which are already backed up

    Everybody who uses an android phone has a Google account. Google provides us with a Photos account in which we can store up to 15GB of data for free.
    If you have turned on the Sync option then all your photos and videos will get automatically backed up to the Photos account.
    If you open your Photos app it will show you how you can free up X GB of space from your phone.
    Select the Free up space option from the menu and the Photos app will tell you how many pictures it can delete from your local storage. Tap Ok to confirm.
    This next method requires you to delete junk files manually on your android phone.

  4. Erase unused Google Maps data

    The latest version of Google Maps allows you to download the map of any route or place which makes it easy for you to navigate when you visit any new place. But downloading these maps will consume a lot of your storage space. It all depends on the size of the map you have downloaded.
    For example, if you download the map of a route it may consume anywhere from XX Mb to XXX Mb. But if you download the map of a city or a state then it will easily consume X Gb to XX Gb of storage space.
    If you want to check how much space offline maps have consumed then open Google Maps and choose Offline maps. Now it will show a list of different offline maps and the amount of storage space it consumes.
    Tap on each map to delete it.

  5. Delete Torrent files

    We all download a lot of stuff from Torrent sites such as games or movies.
    But once we are done with watching movies or installing games we tend to forget about them.
    Instead, we keep on downloading more and more and forget about them.
    Depending upon your preferred storage location head over to the download folder and delete all the watched movies and games.

  6. Start using an SD card

    A few years back you used to get a specific slot for inserting the SD card in your android phone.
    But nowadays since mobile phones are dual sim the extra sim slot can be used for both SIM card and SD card.
    The mobile manufacturer clearly mentions up to what GB you can expand your mobile’s storage without affecting the performance of the phone.
    So as soon as you figure out the expandable storage space head over to Amazon and buy an SD card.
    Installing an SD card doesn’t require you to format anything, you need to only insert the SD card in its slot and you will be able to use the extra storage space generated by the SD card.
    Here are some videos on how to insert an SD card on your mobile phone.

  7. Start using Google Drive

    With every Google account, you are given 15 GB of storage space for free.
    You can store any data inside this Google Drive.
    Uploading files and folders to Google Drive is very easy.
    1.) Just open the app.
    2.) Click on the + button on the bottom right corner.
    3.) Now you can upload any file or folder to Google Drive.
    Uploading your data to GD frees up a lot of storage space which you can use it for storing something else.
    If 15GB is not enough for you, you can expand it to 100GB for just $1.99 per month and 200GB for $2.99.

  8. Start using SD Maid storage cleaner

    SD has a 4.6 rating and over 10 million downloads. It is a very handy tool in which you can perform a lot of operations such as:
    1.) Corpse Finder: Corpses are the files that do not belong to an application that is no longer installed. The app scans your internal storage and SD card to find any such files.
    2.) System Cleaner: It scans for known files which can be safely deleted.
    3.) App Cleaner: It scans the files which can be safely deleted.
    4.) Duplicates: It will show you all the files that have their duplicates in the system. It is performed by comparing checksums and sizes and not by filenames and dates.
    5.) Storage analyzer: It shows what all is taking up your storage space.
    Download the SD Maid app from Play Store.

  9. Delete least used apps

    Since a lot of games and apps on the play store are free which means we can download as many as want.
    But the downside of doing this is that we overstuff our mobile phones with a lot of unnecessary apps and games which we used only once or in some cases we downloaded it and never used it.
    The only solution left is to delete those apps which you use the least or never.
    You can find how many times have you used a particular app without downloading any third-party app by following these steps:
    1.) Open Play store.
    2.) From the menu, tab open My apps & games.
    3.) Now tap on the three horizontal lines at the top right-hand corner and select Last used.
    Now you will see a list of all the apps when you last used them.

  10. Perform a factory reset

    The ultimate weapon on this list of how to delete hidden files on an android phone is Factory Reset. With this, you can remove junk files from android phones programmatically.
