Android multimedia storage: what it is, why it fills up and how to clear it properly

Have you ever noticed that your Android smartphone suddenly runs out of space even though you haven't downloaded new ones for a long time applications or files? The culprit often turns out to be a mysterious multimedia storage memory section that can take up gigabytes of data, but remains invisible to most users. This system cache accumulates photos, videos, audio and even thumbnails from instant messengers, social networks and other applications.

The problem is that Android does not always manage this storage correctly: some files are duplicated, others remain after deleting applications, and others simply accumulate over the years. As a result, you get clogged memoryslow operation of the gadget and constant notifications about lack of space. But you need to clean out this storage carefully - incorrect actions can lead to the loss of important media files or application failures.

In this guide we will figure out which files can be deleted without risk, and which ones should not be touched. You'll also learn how to clear media storage on different versions of Android (including What exactly is stored in this section, which files can be deleted without risk, and which ones should not be touched. You will also learn how to clear media storage on different versions of Android (including Android 13/14) and what tools will help automate this process. And for those who are afraid of losing data, we have prepared a backup checklist.

What is multimedia storage on Android and why do you need it?

Multimedia storage (or Media Storage) is a system component of Android that is responsible for indexing and storing all media files on the device. It includes:

• 📷 Photos (including thumbnails and gallery cache)
• 🎵 Audio files (music, podcasts, notification sounds)
• 🎬 Video (videos, streams, cache video players)
• 📄 Documents (PDF, presentations with media attachments)
• 🔄 Application cache (thumbnails from Telegram, WhatsApp, VK etc.)

The main task of this storage is to speed up access to files. For example, when you open a gallery, Android does not scan all the memory again, but takes data from the index Media Storage. However, over time, this index grows, and the files themselves may be duplicated or remain after deleting applications.

On some devices (especially from Samsung, Xiaomi and Huawei) the multimedia storage can take up up to 5–10 GB —and this despite the fact that the user has not saved new files for a long time. This is due not only to the cache, but also to the operating features of proprietary shells (for example, One UI or MIUI).

Why the multimedia storage is full: 5 main reasons

If you notice that the partition Media Storage takes up too much space, most likely one of these things is to blame:

1. Duplication files. Android can create copies of photos when editing (for example, in Google Photos or Snapseed), but does not always delete the originals.
2. Messenger cache. Telegram, WhatsApp and Viber save thumbnails and previews of media files even after they are deleted from the chat.
3. Residual application files. After uninstalling apps (for example, TikTok or Instagram) their media files may remain in memory.
4. System thumbnails. Android generates previews for all images and videos, even if you did not open them.
5. Indexing errors. Sometimes the system “forgets” to remove files from the index after they have been moved or deleted.

This section grows especially strongly among users who actively exchange media in instant messengers or often edit photos. For example, if you regularly save stories from Instagram or download memes from VK, the cache can grow to several gigabytes in a couple of months.

How to check how much space your media storage takes up

To understand whether you need to clear Media Storagefirst check its capacity. You can do this in several ways:

Method 1: Through the Android settings

1. Open Settings → Storage.
2. Click on the section Other applications or System applications (the name depends on the Android version).
3. Find Multimedia storage (Media Storage) and see how much memory it takes up.

Method 2: Through the file manager

Use any file manager (for example Files by Google or Solid Explorer) and check the following folders:

• 📁 /storage/emulated/0/DCIM/.thumbnails — photo thumbnails
• 📁 /storage/emulated/0/Pictures — images from applications
• 📁 /storage/emulated/0/Android/media — media files applications

If the storage volume exceeds 1–2 GB, you should think about cleaning it. However, before doing this, be sure to back up your important files!

How to distinguish system files from user files?

System files usually have extensions .nomedia, .thumb or are stored in folders with a dot at the beginning of the name (for example, .thumbnails). You can delete them, but only if you are sure that they are not needed for the applications to work.

How to clear multimedia storage without losing data: step-by-step guide

Cleaning Media Storage requires caution. Below are safe methods that will not damage your photos or videos.

Method 1: Clearing the cache through settings

1. Go to Settings → Applications → All applications.
2. Find Multimedia storage (or Media Storage).
3. Click Storage → Clear cache.
4. Restart the device.

Method 2: Removing unnecessary thumbnails

Thumbnails take up a lot of space, but they can be deleted manually:

1. Open a file manager with root access (for example, Root Explorer) or use Files by Google.
2. Go to the folder DCIM/.thumbnails.
3. Delete all files with the extension .thumb.
4. Restart your smartphone.

Method 3: Using specialized applications

For automated cleaning, the following are suitable:

• 🧹 CCleaner (section Junk cleaning)
• 🗑️ SD Maid (function CorpseFinder to search for residual files)
• 📱 Files by Google (tab Cleaning)

If After cleaning, some applications (for example, gallery) work more slowly, do not be alarmed - Android will rebuild the index of media files within a few minutes.

What happens if you delete the media storage completely

Some users try removing the "Multimedia Storage" application itself via ADB or with root access. This extremely risky and can lead to:

• ❌ Loss of access to gallery (photos will remain, but will not be displayed)
• ❌ Camera malfunctions (will not save new pictures)
• ❌ Errors in messengers (media previews will not be displayed)

If you decide to take radical measures, first create a full backup via Titanium Backup or Swift Backup. And remember: on some firmware (for example, MIUI or ColorOS) deleting Media Storage may lead to data-i="173">(the device will boot, but many functions will stop working). soft-brick (the device will boot, but many functions will stop working).

How to prevent the media storage from filling up in the future

To avoid encountering the problem again, follow these tips:

1. Regularly clear the messenger cache. There are built-in tools for this ( Telegram And WhatsApp there are built-in tools for this (Settings → Storage).
2. Use cloud services. Set up automatic uploading of photos to Google Photos or Yandex Drive and delete local copies.
3. Disable automatic media saving. In messengers (for example, VK or Instagram) disable the "Save to gallery" option.
4. Set a cache limit. In some firmware (for example, One UI) you can set a limit for media storage.

It is also worth periodically checking the Download and DCIM folders for unnecessary files. For example, many users do not suspect that TikTok or Likee save videos in these directories even without explicit permission.

Common mistakes when cleaning media storage and how to avoid them

Many users make critical mistakes when trying to free up space. Here are the most common ones:

Error	Consequences	How avoid
Deleting a folder DCIM entirely	Losing all photos and videos	Delete only the contents of the folder .thumbnails
Clearing the cache through ADB without backup	Gallery or camera malfunction	Use the command pm clear com.android.providers.media only after backup
Deleting files .nomedia	Appearance of unnecessary files in the gallery	These files hide folders from scanning - do not touch them
Using "cleaners" with aggressive settings	Deleting important system files	Configure cleaning manually, excluding system folders

If after cleaning, you notice that some photos have disappeared from the gallery, but the space taken up has not decreased; most likely, the files are still in memory, but not indexed. In this case, rebooting the device or forcing an index update via Settings → Applications → Media storage → Stop/Start will help..

FAQ: Answers to frequently asked questions about Media Storage

Is it possible to completely remove the Media Storage application?

No, it is a system application that is required for Android to function. Removing it will lead to failures in displaying media files. The maximum that can be done is to clear its cache.

Why is space not freed up after clearing the media storage?

Probably, the files are still taking up space, but are not displayed in the gallery. Check the folders manually through the file manager or use the application DiskUsage to analyze the memory.

How to clear the media storage on Xiaomi/Redmi?

On devices with MIUI go to Settings → Applications → Manage applications → Three dots (menu) → Show all processes. Find Multimedia storage and clear the cache.

Is it safe to use CCleaner for cleaning?

Yes, but only in manual mode. Automatic cleaning can remove the files you need. Check only items related to the multimedia cache.

What to do if photos are missing after cleaning?

Check the folder DCIM via the file manager - the files might remain in place, but not be displayed in the gallery. If they are not there, restore from a backup or using apps like DiskDigger.

If you were unable to free up space or had problems after cleaning, try an alternative method: connect your smartphone to your PC and manually check the folders for large unnecessary files. Sometimes the culprits are not media, but system application logs or error dumpswhich also take up gigabytes.
