Archive Your RA File in 7Z Format
Learn how to convert RA audio files into high-compression, secure 7Z archives. Preserve your legacy RealAudio collections with efficient compression and encryption.
Quick Access To 3 RA File Conversion Pairs
What Is This Tool?
This tool enables you to archive RA audio files into the 7Z format, combining multiple RealAudio files into a single compressed and optionally encrypted archive. It helps organize, reduce storage space, and securely back up legacy streaming audio files without altering the original RA audio streams.
How to Use This Tool?
- Upload one or more RA files or folders containing RA audio files
- Choose 7Z as the output archive format
- Select compression options such as LZMA2 and enable AES-256 encryption if desired
- Optionally configure multi-volume split archive settings for large collections
- Start the archiving process and download the resulting 7Z archive
Key Features
- Convert RA audio files into a 7Z archive preserving directory structure
- Use LZMA/LZMA2 for high compression ratios and solid compression
- Support AES-256 encryption for secure backup with optional header protection
- Create multi-volume split archives for easy transfer or storage with size limits
- Open format compatible with free cross-platform extractors like 7-Zip
Examples
- Archive a directory of legacy RA webcasts into a single encrypted 7Z archive for secure offsite backup
- Create split 7Z volumes from a large RealAudio podcast collection for easy distribution across different media
- Package multiple RA files preserving their folder structure into a compressed 7Z archive to save disk space
Common Use Cases
- Bundling archived webcasts, podcasts, or legacy RealAudio libraries into one compressed archive for easy storage or sharing
- Creating encrypted backups of RA audio collections to protect sensitive legacy content
- Preparing multi-volume archives for transferring large collections of RA files with file size limits
Tips & Best Practices
- Use LZMA2 compression for better performance on modern systems
- Enable AES-256 encryption to secure your archived RA files from unauthorized access
- Create split archives when dealing with very large RA collections to facilitate transfer
- Ensure recipients have compatible extraction tools like 7-Zip that support all 7Z features used
- Remember that archiving doesn't improve RA playback compatibility—RealPlayer or compatible decoders may still be needed
Limitations
- Archiving RA files into 7Z does not alter the RA codec or improve audio playback compatibility
- Solid compression can slow extraction and modification of individual RA files compared to non-solid archives
- Extracting and decompressing 7Z archives may be CPU- and memory-intensive on systems with limited resources
- Some operating systems do not natively support 7Z; third-party tools like 7-Zip are required to access the archive
- Not all extractors support newer compression features such as LZMA2 or header encryption used in 7Z
Frequently Asked Questions
- Why should I convert RA files to 7Z archives?
- Converting RA files to 7Z archives helps reduce storage space through high compression, preserves directory structure, enables secure encryption, and allows multi-volume splitting for easier transfer and long-term backup.
- Will archiving RA files in 7Z format improve their playback compatibility?
- No. Archiving RA files into 7Z does not change their codec or playback requirements. You still need RealPlayer or compatible decoders to play RA audio.
- Do I need special software to open 7Z archives containing RA files?
- Yes. Most operating systems do not natively support the 7Z format. You will need a tool like 7-Zip that handles modern 7Z features including LZMA2 compression and AES-256 encryption.
Key Terminology
- RA
- A proprietary audio format developed by RealNetworks designed for low-bitrate streaming and progressive playback of audio.
- 7Z
- An open archive format that compresses multiple files and folders with high compression and supports encryption and multi-volume archives.
- LZMA2
- A compression algorithm used in 7Z archives that provides high compression ratios and improved performance on modern CPUs.
- AES-256
- A strong encryption standard used to secure contents and headers within 7Z archives.
- Solid Compression
- A compression technique in 7Z archives that compresses multiple similar files together to increase efficiency but can slow individual file extraction.
