File extension .BLOB
The BLOB file format is an asset format employed by Valve Steam software to store data, largely used for game content such as 3D models, textures, audio, videos and game levels. Files using this format are identified by the .blob extension. It is created when the Steam client's content system pre-loads files from a manifest on run time for Valve Source games.
Features and Usage
The BLOB file's binary content depends on the game; it could represent graphics, audio, video formats, etc. It can also contain non-game relevant data, such as spritesheets and miscellaneous animation images. Some other similar source file extensions employed by Steam are: .bin, .vpk, .wem, and .wad. In addition to this, The BLOB file can work in conjunction when building certain maps or working within specific offices on a game scenario.
Developers can compress the files under BZIP2 or LZMA for delivery through Steam; likewise, the files can also be encrypted under the Rivest–Shamir–Adleman (RSA) algorithm. The combination of both compression techniques reduces the size of the BLOB file dramatically, making them easier to store and transfer.
Due to its game content related use, the .blob files are mostly seen in specific gaming libraries or Steam client applications. Besides Valve Steam, other compatible applications like Winrar, 7Zip, etc., can open .blob files to access their content.
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BLOB) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BLOB extension.
When choosing the software we can select the system to use this software every time.
Using it for the first time it is good to check whether the .BLOB file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BLOB extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BLOB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BLOB file. Sometimes you have to repeat the operation several times.
If none of the programs listed by us to work with the .BLOB file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BLOB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BLOB file) will be extended to the maximum.
It is also good to check
- if the .BLOB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
