7-zip default compression level (split from solid block thread)
: To extract a specific file from the middle of a solid archive, the software must decode all preceding data in that block, which can be slower than extracting from a non-solid ZIP archive. JSB1213GcP1.7z
You can manage these settings in the 7-Zip interface by adjusting the , which determines how many files or how much data is grouped into a single stream. 7-zip default compression level (split from solid block
: By treating files as a single stream, the algorithm (usually LZMA or LZMA2 ) can find redundancies across different files, significantly reducing the total size—especially if the files are similar. Seeing this list and considering that this means
Seeing this list and considering that this means that 5 = Normal for 7-Zip, I wonder why TC uses "normal compression (6)" in the " ghisler.ch
In a solid archive, multiple files are concatenated and treated as a . This approach offers several advantages and trade-offs:
: If a solid archive becomes corrupted, it may be impossible to recover any files within the damaged block, whereas non-solid archives often allow for the recovery of undamaged individual files.
