ARIA2 File – What is .aria2 file and how to open it?

ARIA2 Control File

ARIA2 control files are text-based files used to configure and control the behavior of the ARIA2 download manager. They contain a series of commands that specify the download parameters, such as the URLs of the files to be downloaded, the destination directory, and the maximum number of simultaneous connections. ARIA2 control files can be created and edited using any text editor, and they can be loaded into ARIA2 using the “-c” option.

ARIA2 control files are particularly useful for automating the download process. For example, you could create a control file that specifies the URLs of all the files you need to download, and then load that file into ARIA2. ARIA2 would then automatically download all of the files specified in the control file. This can save you time and effort, especially if you need to download a large number of files.

In addition to specifying the download parameters, ARIA2 control files can also be used to define global settings for ARIA2. For example, you could use a control file to set the default destination directory for downloaded files, or to set the maximum number of simultaneous connections. This can be useful if you want to use ARIA2 to download files in a specific way.

Identifying and Opening ARIA2 Files

ARIA2 files, characterized by the .ARIA2 extension, are text-based files that typically instruct the aria2c download utility to perform specific actions. Aria2c is a command-line download manager commonly employed in Linux systems and other environments. ARIA2 files can contain download links, configuration settings, and other parameters necessary for the efficient management of file downloads.

To open and utilize ARIA2 files, users need to have the aria2c utility installed on their system. Once installed, you can open an ARIA2 file by double-clicking on it or by dragging and dropping it onto the aria2c executable. Alternatively, you can navigate to the directory containing the ARIA2 file in a terminal window and type the following command to open the file:


aria2c <path/to/ARIA2_file>


Upon opening, aria2c will parse the ARIA2 file and initiate the download process based on the specified parameters. If any errors occur during the download, the associated error messages will be displayed in the terminal window, providing insights into the issue.

ARIA2 File Format

ARIA2 (Advanced Rapid Incomplete Download AcceleratoR) is a free and open-source download utility that supports HTTP, HTTPS, FTP, SFTP, BitTorrent, and Metalink. It can resume interrupted downloads, supports multiple concurrent downloads, and has a web interface for remote control.

ARIA2 Control Files (.ARIA2) are text files that contain instructions for ARIA2 to download a specific file or set of files. They typically include the URL of the file to be downloaded, the download destination, and various options such as the number of concurrent downloads, the maximum download speed, and the user agent to be used. ARIA2 Control Files can be created manually or generated by other applications, such as web browsers or download managers.

Using ARIA2 Control Files

To use an ARIA2 Control File, simply open it in ARIA2. ARIA2 will then parse the file and start downloading the specified files. You can also use the aria2c command-line tool to download files using ARIA2 Control Files. For example, the following command will download the file example.txt using the ARIA2 Control File example.aria2:


aria2c --conf-path=example.aria2


ARIA2 Control Files are a convenient way to manage and automate downloads. They allow you to specify all of the necessary download options in a single file, which can save time and effort.
