Memory, eh...
I came up with couple of dozens of possible passwords when trying to use ZIPCracker. Nothing worked... I really protected that file
I remember at that time I was for some reason pressed to change the password, and the od one dissapeared into oblivion.
Brute force attack is probably not practical because I think there may be 8-12 characters in that password. It will take time to crack it...
Anyway, thank you all for your help.
