Convert ARC to 7Z

Understanding ARC and 7Z file formats

ARC is a legacy compressed archive file format developed in the 1980s, primarily used for bundling and compressing multiple files into a single archive. It is now considered obsolete, but you may still encounter ARC files in old software distributions or backups.

7Z is a modern, high-compression archive format created by the 7-Zip project. It supports advanced compression algorithms, strong encryption, and is widely used for efficient file storage and sharing.

Why convert ARC to 7Z?

Converting ARC files to 7Z format allows you to benefit from better compression ratios, improved compatibility with modern systems, and enhanced security features. 7Z files are supported by many popular archiving tools, making them easier to manage and share.

How to convert ARC to 7Z

Since ARC is an outdated format, not all modern archivers support it directly. The recommended approach is to first extract the contents of the ARC file, then re-compress them into a 7Z archive.

Best software for ARC to 7Z conversion

PeaZip is a free, open-source archiver that supports both ARC extraction and 7Z compression. Here’s how to use it:

1. Download and install PeaZip.
2. Open PeaZip and use File → Open to locate your ARC file.
3. Extract the ARC archive to a folder using Extract.
4. Select the extracted files, then click Add to archive.
5. Choose 7Z as the archive format and click OK to create your 7Z file.

Alternatively, 7-Zip can be used for the second step, but it does not natively support ARC extraction. For command-line users, unar (for ARC extraction) and 7z (for 7Z creation) are also options.

Summary

To convert an ARC file to 7Z, extract the ARC archive with a compatible tool like PeaZip, then compress the contents into a 7Z file. This process ensures your files are stored in a modern, efficient, and widely supported format.
