What are media files on a smartphone? What is a media file? A file that contains audio, video, graphic or text information, or combinations thereof. Using a computer

Tired of the system constantly turning on multimedia search? Are unnecessary pictures or videos displayed in the gallery? Solved in one step.

Sometimes, in fact, there is such a problem that some application caches pictures (news applications are very fond of this), and because of this, after some time the gallery becomes a complete garbage dump.

And if the system suddenly needs to check once again whether anything has changed in the multi-gigabyte folder with music, then you can be left with a seriously slow device for several minutes.

In general, automatic search for multimedia files is useful, but not when there are a lot of them or there is something that turns the gallery into a trash heap.

To solve this, you just need to create an empty file in the folder with such files called “.nomedia” (without quotes, of course). That is, for example, we create any file (“123.txt”, for example) using Notepad and simply rename it to “.

nomedia". Anyone who wants to speed up this process can use the free StudioKUMA .nomedia Manager application, with it you just need to select the folder where you want to hide files from search. The system search for multimedia files will not look for anything else in this folder.

The only thing to consider in this case is that if necessary, the files in this folder will need to be opened manually. A very useful feature when using a music player like PowerAMP, or in the case of video -

The Android operating system consists of thousands of components, many of which are represented as individual files. Moreover, some of these components can also generate their own files, some of which are hidden and do not appear in the file manager. However, if you install a third-party drive browser and enable showing hidden files, you can see them. These files include dthumb and nomedia. Below we will figure out exactly what these dthumb and nomedia files are on Android.

File dthumb can be found in the directory where images are stored. In such folders, the operating system creates a hidden section called “.thumbnails” (the dot before the name in Unix like operating systems means that the section should be hidden), and in them, in turn, the files themselves are stored, the names of which contain dthumb and some other symbols (for example, numbers).

The system writes thumbnail images to the dthumb and nomedia files. This is necessary so that they are not generated anew each time and once again do not heavily load the device’s resources.

These files are not a problem in most cases, however, in some cases their presence may not be desirable. They can grow to very large sizes - up to several gigabytes. The growth of these files is caused by a large number of images (for example, photos) on the device. I hope it became clear to you what dthumb is and you decided what to do with it.

If you find a program on your Android device and don’t know what it is, follow the link.

Is it possible to delete these files?

What happens if you delete the corresponding files? Nothing critical. It’s just that now when you open a list of images through the standard gallery application, the smartphone will create new thumbnails. As a result, the files will be created again.

Deleting dthumb files is only useful in cases where a significant number of images have been deleted from the device's memory (for example, stored photos have been copied to a computer). In this case, you can delete the dthumb and nomedia files, thereby removing thumbnails of pictures from the device that are no longer on the smartphone.

Yes, there is a way to prevent this file from being created in the future. To do this you will need:

  1. Delete the “.thumbdata” directory;
  2. Create a new file (not a directory) that will be named ".thumbdata".

In this way the system will be deceived. However, you should think before doing this. It may be better to sacrifice a few hundred megabytes of storage than the processing power of the device.

What is this nomedia file?

Android has many features that many people are not aware of. One of them is implemented by adding a special file - with the extension nomedia– to the directory with multimedia files.

The purpose of this file is to tell the operating system that files in this directory should not be indexed. Thus, if you create a nomedia file in a directory with images, then pictures from the corresponding folder will not be displayed in the gallery; if you create it in a folder with music, then these tracks will not be present in the list of tracks in the player. I hope it became clear to you that this is nomedia and you decided what to do with it.

The nomedia file size is 0 megabytes because it is always empty.

What's new

ℹ️※What can it do?
1. Create ".nomedia" file in the directory signaling the media scanner to ignore media, so as to hiding useless and redundant media file(image/photo, music, video) in Gallery, Music Player, Video Player and other APP base on media store.
2. Use as a media scanner, find out all the media file(image/photo, music, video) on your device, and update to the media store, so you can view the media file in Gallery, Music Player, Video Player and other APP base on media store.
ℹ️※ What is this:
This APP can help you to create or remove a file called .nomedia in a
folder contains media files easily. So what is a .nomedia file? If a folder
contains a .nomedia file, then the android system MediaStore will not scan
it for media files, so that Gallery(and other media APP based on MediaStore) will NOT load the media files from the folder.
If you want to scan all the photo/image/music/video on your device;
If the Gallery, Media Player always load some pictures, videos or audios which you do think are useless, redundant.
Then this APP may be what you need.
Note:
The main purpose of this app is let the junk media files(which we do think) don"t show in some APP(such as the Gallery, Play Music) based on MediaStore. It is not a tool to hide files and protect your privacy , as files may be shown in file manager APP.
ℹ️※ How to use:
1. The application will scan picture, video, audio files from the MediaStore and file system, and then classify them by folder.
2. When a folder is set to "ON," means that media files in this folder will not be scanned by MediaStore, otherwise will be scanned.
3. In the list view, click the folder preview to view folder detail.
4. In the grid view, click the file preview can play the media file.
Note: This APP may NOT work on SOME devices. Anyway you can try it out.

Any user of computer systems, mobile devices or the Internet encounters multimedia files almost every day. What is a media file? It is proposed below to consider this issue in more detail. However, there is nothing particularly difficult in understanding the entire concept of multimedia.

What is a media file in the general sense?

Let's start, perhaps, with the most basic. As a rule, multimedia includes everything that is associated with video, audio and graphics files or a combination of them, and even with the content of texts. By and large, even presentations created in Power Point, which contain one or more of the above objects, can also be classified as some kind of multimedia, although it is believed that this is a presentation, and not multimedia, only for the simple reason that such files are software or cannot be played by hardware players.

It is these three large groups that represent the main directions of the entire multimedia category. However, for all three classes, an additional classification can be given, dividing them by format or content. So, for example, in the video category, in terms of content, there may be films, cartoons, clips, video cards, advertising materials, etc.

And if in each class you also dig into the variety of formats, there will not be enough time to describe them all, since today in the computer world there are not even tens - hundreds of them. But speaking about what a media file is, it’s worth considering each category separately.

Audio

Audio or sound files are one of the largest categories, which combines a huge number of different formats.

At the dawn of their appearance and creation, the PCM WAVE format, which was developed by Microsoft Corporation, was initially used. But files of this type were very large in size and storing them on small hard drives or removable media in the form of floppy disks was quite problematic.

Everything changed when a special codec, Fraunhofer MP3 Encoder, was developed, which made it possible to compress audio information while reducing the size of the original WAV file. True, with a slight loss of quality at the level of a decrease in sound characteristics (sampling frequency, sound depth, etc.). However, today the MP3 format has been improved so much that not only the difference in sound is unnoticeable, but sometimes files of this standard, for example, with a bitrate of 320 kbps, sound much better than any other format.

Speaking about what a media file of the audio category is, it can be noted that recently quite common and popular formats are the following:

  • AIFF;
  • FLAC;
  • CDDA;
  • DVD Audio and many others.

Some of these formats are independent and can be played by any players. Others are audio tracks that are embedded into the video. If we also take highly specialized formats of music programs (for example, the FLP format for the FL Studio sequencer), the number of formats increases simply incredibly.

Video

Another big class is video. In this case, videos can contain audio, video, graphics, text (for example, subtitles), etc. There are also a lot of formats in this category.

The most common are the following:

  • DivX;
  • Xvid;
  • MPEG;
  • RealVideo;
  • 3GP, etc.

It’s simply impossible to list everything that exists in this category today. However, there is one caveat. It happens that the player does not play media files of this type. Why? Yes, only because each standard requires the use of special programs called codecs and decoders (this will be discussed separately).

Graphic arts

Finally, another large class of multimedia is graphics. Here, perhaps, you can count the most different formats. In addition, you can separate stationary images and animation, which, although related to graphics in format, is closer in content to video, or raster and vector images. The simplest example is a GIF file. By the way, they can equally be attributed to the so-called mixed files.

As for the graphic files themselves, the matter is not limited only to standard image formats. If we take into account engineering, design or drawing software packages like AutoCAD, their “native” formats can also be safely classified as a variety of graphic objects.

Mixed media

What is mixed media? The easiest way to explain this is with PDF documents, which can contain both graphics and text.

Despite the fact that special programs like Adobe Reader are provided for viewing or editing them, and not standard tools used for graphic images, they also, in a sense, represent a type of multimedia.

Creating Media Files

As for creating or editing multimedia, each category has special tools in the form of highly focused editors or programs that combine several capabilities.

Sound files can be created (recorded) or edited not only in specialized applications such as Adobe Audition, Sound Forge or ACID, but also using video programs, which, in addition to video processing, also have tools for audio editing. One of the most powerful is the Sony Vegas Pro program. But in fact, today you can find quite a lot of such applications of different levels. Naturally, they all differ in their capabilities and the professionalism of the result obtained.

Well, if you look at the utilities for creating and processing graphics, there is so much here that an inexperienced user will simply get lost in this huge list when choosing the necessary utility.

Codecs and decoders

It is worthwhile to dwell separately on codecs and decoders, which are necessary not only for the correct playback of certain types of multimedia, but also for converting formats. Moreover, the same video codec can be used in some converter to convert video to audio and vice versa.

The most popular and most widespread packages with a full set of necessary tools are K-Lite, which, depending on the modification, may contain a different number of codecs and decoders. The most complete package is considered to be the K-Lie Mega Codec Pack, which contains absolutely all decoders and codecs known today. After installation, any video codec or audio decoder is built into the operating system, programs for playing or processing multimedia automatically, so there should be no problems with their use. Only at the installation stage it is necessary to note everything that needs to be installed.
