Many smartphone owners, when auditing the internal memory, are surprised to discover hidden or little-known directories with unclear names. One of these mysteries for users is often a folder covers, which can weigh from several megabytes to gigabytes. A reasonable question arises: what is stored in this directory, is it systemic and can it be deleted without harm to the operation of the device.
In this article we will examine in detail the nature of the origin of this directory. You will learn what applications create these files, why they tend to grow uncontrollably and how to properly manage their contents in order to free up valuable space on the drive of your Androidgadget.
The origin and purpose of the directory
The name of the folder comes from the English word "cover", which means cover or covering. In the context of a mobile operating system, this storage is intended to cache graphics that serve as visual decoration for media content.
Most often, this folder is created by music players, podcast applications, or file managers scanning a library of tracks. When you open a song or album, the app reads embedded metadata (ID3 tags) or downloads an image from the Internet to display it on the screen.
To avoid wasting time and bandwidth re-downloading the same image every time, the application saves it locally. Thus cover cache speeds up the interface and makes navigation through the media library more visually pleasing.
However, over time, the music collection may change, and old files are not always deleted automatically. As a result, the folder turns into a “trash can” filled with thousands of thumbnails that you may never see again.
What applications create files in the folder
The source of this directory can be various apps that work with audio and video. A standard system player from a smartphone manufacturer can also use this directory to store album art.
Third-party developers often choose this name for their cache files, since it is a generally accepted standard. Among the most active creators of such a folder are:
- 🎵 Music players (Poweramp, BlackPlayer, standard player) - scan memory and save album covers.
- 🎧 Streaming services (Spotify, Yandex.Music) - cache track images for offline mode or fast access.
- 📁 File managers —some advanced explorers generate previews for audio files when viewing folders.
- 📻 Applications for podcasts and radio —save app logos and issue covers.
It is important to understand that the folder itself is not a virus or malware. This is a legitimate service directory that simply got out of control due to the way caching algorithms work.
⚠️ Attention: If the covers folder appeared suddenly and is consuming a huge amount of memory, check whether you have recently installed a new music application. Sometimes incorrect app settings lead to duplicate files.
Analysis of file content and format
Looking inside the directory, you will see many files with unclear names, often consisting of a set of numbers and letters. These are hash sums or unique identifiers that the application uses to quickly find the desired image.
The format of the stored data is usually standard for web and mobile systems. Most often these are raster graphics with extension .jpg or .png. More modern compression formats are less common.
The size of each individual file can vary from 10 KB to several megabytes, depending on the quality of the source image and application settings. Some players save covers in full resolution, which wastes space.
It is not necessary to open every file to analyze the content. It is enough to sort them by size in the file manager. You will immediately see which images take up the most space and whether they are really needed.
Use a third-party file manager with the "Storage Analysis" function to visually see how much space the covers folder takes up compared to other data.
Sometimes in this folder you can find files with the extension .nomedia. This hidden file tells the gallery system to ignore this folder so that your album covers do not become an eyesore in the general flow of photos.
Impact on memory space and performance
Cache accumulation of covers is one of the common reasons for lack of free space on smartphones with a small amount of internal memory. Over the course of a year of active music use, this folder can grow to 500 MB or more.
Although modern memory files are large, cluttering the storage with thousands of small files can negatively affect the speed of the file system. The process of indexing such volumes of data requires processor resources.
Below is a table showing the approximate effect of the number of tracks on the folder size for different caching quality settings:
| Number of tracks | Cover quality | Approximate folder size | Impact on the system |
|---|---|---|---|
| 100 - 500 | Low (preview) | 5 - 20 MB | Insignificant |
| 1000 - 3000 | Average | 100 - 300 MB | Noticeable memory |
| 5000+ | High (original) | 1 - 3 GB | Critical slowdown search |
If you are the owner of a device with 32 or 64 GB of memory, clearing this folder can free up a significant percentage of free space, which is enough to install a couple of heavy games or save videos.
Regularly cleaning the covers folder can free up to 1 GB of space on devices with a large media library, without affecting the operation of the smartphone itself.
Safely deleting and clearing cache
Many users are afraid to delete system folders for fear of breaking the phone. In the case of a directory covers the fears are in vain. Deleting this folder is completely safe for the operating system.
The only consequence you will encounter is the disappearance of album images in the player when you first start it after cleaning. The application will automatically re-download or count covers from the files the next time it is played.
To delete, follow these steps:
- Open the file manager (Explorer).
- Go to the root of the internal memory or to the folder
Android/data(depending on the OS version). - Find the folder
covers. - Select it and press the delete button.
If the system says that the file is busy or cannot be deleted, try closing all music applications through the multitasking menu. Sometimes the caching process runs in the background and blocks access to files.
☑️ Safe cleaning checklist
An alternative method is to use the built-in cleaning tools. Go to Settings → Applications, find your music player and select "Clear cache". This will delete covers only for a specific application, without affecting others.
⚠️ Attention: Do not delete the folder itself if you use specific software that stores not only pictures, but also interface settings there. In 99% of cases, these are just pictures, but it doesn’t hurt to be on the safe side.
Setting up automatic cleaning and prevention
To prevent the problem from returning, you can set up automatic garbage cleaning. Many modern Android shells (for example MIUI, OneUI) have built-in optimizers that periodically clear the application cache.
Also, in the settings of the music players themselves there is often an item that limits the cache size or prohibits saving covers in high resolution. Disable downloading covers via mobile network, if possible.
You can use specialized cleaning utilities such as Files by Google or SD Maid. They can find “empty” or outdated cache files and delete them on a schedule.
If you store music on a memory card, make sure that the path to the covers folder does not lead to the internal drive. Some applications allow you to select the path to save the cache in the settings.
What should you do if the folder appears again immediately after deletion?
This is normal behavior. The application sees that the cache is empty and starts filling it again the first time you turn on music. To stop this, you need to limit the cache size in the settings of the application itself.
⚠️ Attention: Application settings interfaces may differ depending on the version of Android and the smartphone manufacturer. If you do not find the cache limit item, check the official help of the player developer.
Frequently asked questions (FAQ)
Is it possible to move the covers folder to a memory card?
You cannot move the folder itself manually, since the application will search for it using the old path and create a new one. However, in the settings of some advanced players, you can change the directory for storing data on an external SD card.
Why did the covers in the player turn black after deleting?
This happens because the cache is cleared, and the application has not yet had time to re-read tags from music files or download images from the network. Just enable any trick and the picture will be loaded automatically.
Is the covers folder a virus?
No, this is a standard system folder for graphics caching. Viruses are usually disguised as system files with different names or hidden in root directories without a name.
How much space can be freed by deleting this folder?
The amount depends on your media library. For the average user with several thousand songs, you can free up from 200 MB to 1 GB of internal memory space.
Do you need to back up this folder?
Backup makes no sense. All images are easily restored automatically from the music files themselves (tags) or from the Internet if necessary.
