What is file format conversion?
File format conversion is the process of changing a file from one format to another to ensure compatibility with software, systems, or devices, while keeping the structural content of the file intact.
The reason for file format conversion is to make the ARC file compatible with the desired software or device that does not support the original format. By supporting various formats, users can use ARC files effectively, ensuring compatibility and seamless information sharing across platforms.
File format conversion can be done using special programs or online tools created for this purpose. The user-friendly interface of these tools allows users to quickly pick the input ARC file, specify the NBU format, and start conversion.
