Command p (Paranoid test (slow, lot of RAM needed)) - EpicGazel/zpaqfranz GitHub Wiki

Test the archive content in a very paranoid fashion.
The ZPAQ reference decompressor is used to extract the various blocks in RAM and check them.
In other words, do not use the 7.15 algorithm to decompress, but that of unzpaq206, so as to avoid the risk of 'silent' bugs.
Essentially it is similar to extracting the entire archive into a temporary folder.
The amount of RAM can quickly become unmanageable.
Doesn't support multifile lile ????.
Shows an estimate of the RAM used (not very precise) during the operation.
For each file will output the SHA-1 of the virtually extracted one.
It is normally used in combination with add() -checksum, which stores the SHA-1 codes, to make a comparison.
It warns on Win32 systems (with RAM limits) and refuses to run on ESXi.

-noeta

Not much to say

-verbose

Show positive match (in fact, everything). By default shows only error

-verify

Next level of paranoia: check hashes against a re-read from filesystem. In other words you will get this checks:
Uncompressed == stored-in-the-archive
Readed-again-from-filesystem == stored-in-the-archive

And yes, another level is coming...:)
