What I meant is that while in TWRP you can unmount your external and internal sd card and have it recognized as an mass storage device by windows. Thus allowing you to move roms, backups etc onto your sd card. Once you're finished with moving files you can remount your sd card and go about your business. I mess something up at least once a week and end up without a usable backup after wiping data in recovery. In the TWRP world I can just copy over a good backup without leaving the recovery. In Philz and cwm recoveries I end up having to reboot to the bootloader, reflash recovery, pull out my sd card and copy my backup to the sd card to get back where I need to be. It's nothing horrible but it does usually add 5 or 10 minutes to the process.
