Restore old multibit wallet I just found an old backup of a bitcoin wallet on a USB stick containing 4 folders:

key-backup - empty
rolling-backup - contains a .wallet file stamped with a date from 2014
wallet-backup - empty
wallet-unenc-backup contains a .info file and a .wallet file

The info file includes this

multiBit.info,1
walletVersion,2
property,walletDescription,Your%20wallet%20description
property,walletBackupFile, *path to the .wallet file*

Is it possible to recover this wallet? I've tried downloading multibit, but the new version needs a phrase (which i don't have) and one of the older versions needs a .key file
I run a service to crack wallet files and, yes, it is possible to recover funds from MultiBit wallet files. 

Usually users password-protect their MultiBit wallet files and if this is the case and you have no idea what the password is, then typically the effort brute-force is too high. 

Since this is a wide topic with many tools to use, I advice to start looking at https://github.com/gurnec/btcrecover and then google for more details. PM me if you get stuck in the process.
