If you're wondering whether to use solid mode for a specific task, let me know:
By treating files as a single stream, solid compression achieves much smaller file sizes than standard methods, especially for large, similar data sets.
7-Zip allows users to define a "solid block size" to balance the benefits of high compression with the drawbacks of slower extraction and potential data loss.
Because the files are linked, if one part of the archive is corrupted, it is more likely to make other files in the same solid block unrecoverable.
Are you compressing (e.g., text, code) or large, unique files (e.g., videos)? Is maximum compression or fast extraction more important? What is solid compression, how to use, advantages - PeaZip
