When Should You Use LZH vs NRG?

LZH vs NRG: Key Differences

• •The core technical difference: LZH relies on lossy compression whereas NRG uses lossless compression.
• •Converting from LZH to NRG changes compression type: lossless source becomes larger but with full quality preservation.
• •Transparency: N/A
• •File sizes: LZH files typically range Slightly better than ZIP for text and NRG files 700MB (CD) to 50GB (Blu-ray).
• •Use case fit: LZH targets japanese software distribution, legacy archiving and NRG targets cd/dvd burning, disc imaging, backups — your choice depends on which workflow stage you are serving.
