Connect Win 7 PC and phone using SMB2.0 only

[AC Question]

Due to the recent Wanna Cry exploit, I have disabled SMB v1 in my Windows 7 PC. I was using the LAN plugin in Total Commander for Android to connect. This uses SMB v1 only so no longer works. I have tried ES File Explorer which gives me a message stating the server requires SMB2.0 but won't connect and tried AndSMB which only works in SMB v1. Can anybody suggest a free apk with no transfer restrictions which will work under SMB v2 and allow me to connect wirelessly?
