Groups similar files together to improve compression efficiency, ideal for thousands of small daily logs.

To create a "FishermansFriend" archive, use the following settings in the 7-Zip GUI or CLI: 7z Compression Level: Ultra (Best for archival) Compression Method: LZMA2 (Best for multi-core processors) FishermansFriend 7z

Highly recommended. This prevents others from even seeing which files are in the archive. C. Splitting Large Data Dumps

-sdel : Delete files after archiving (creates space immediately) Fishery data is notoriously dense (e

Solid (Ensures max compression for similar log files) 3. Workflow Best Practices A. Archiving Sonar Logs (e.g., .DAT/.SL3)

7z often outperforms .zip and .rar on binary sonar data. This prevents others from even seeing which files
