Recover password file .7z partially known

[antwane]

extract the hash with 7z2hashcat first and confirm it looks similar to that of the example hash found on the wiki.

It's a bad start, when I use 7z2hashcat (7z2hashcat64-1.2.exe), I have this message :

Code:

WARNING: the file blablabla.7z' unfortunately can't be used with hashcat since the data length in this particular case is too long (3086944 of the maximum allowed 327528 bytes).
