BB10 File Manager for Android?

I absolutely love the file manager on BlackBerry 10. The reasons being it connects to my box account and allows me to send multiple files from my box account at a time and it sends the spreadsheets themselves, not a link to box. My job requires me to fill out spreadsheets and I have about 60 different ones I edit on a daily basis. I am a contract pumper and I work for about 8 different companies. Those companies have anywhere from 2 to 15 wells each. At the end of the day I have to send all of those spreadsheets to each individual company. I store them in the cloud and love how I can send as many files as I want in one email. Now finally to the reason I made this post. I have a Galaxy Nexus and a Nexus 4. Does anyone know of a file manager that has these capabilities for Android. I have found ones that connect to my box account easily but not send multiple files at once. Both devices are fully rooted and running custom roms. Thanks.
