Adding or removing a single file requires rebuilding the entire archive, making it slow.
Solid archives often show a lower number of pack streams/folders when inspecting properties in 7-Zip.

If the archive is corrupted, it is more likely to lose all data rather than just the corrupted file.
To help you specifically with , could you tell me: Are you trying to extract it or create it? Are you getting any errors ?
