Simple and robust file manager with cloud storages and archive support.

B1 File Manager is a file explorer which allows to:

- unzip over 38 archive formats (multi-volume and password-protected);

- compress files into zip and b1 archives;

- manage the files in internal storage, external SD card and USB-drives;

- manage Dropbox, Google Drive, OneDrive, Box and 4shared cloud storages;

- stream media files from the cloud storages and via SMB with no need to actually download files (NOTE: streaming speed highly depends on your Internet connection speed).

Dear friends, a lot of hard work and efforts went into the development of B1 File Manager and the B1 team needs your support. You might have noticed that B1 File Manager now displays sponsored offers. This is what allows us to distribute B1 File Manger for free. However, we've listened to your feedback and we've introduced an option to disable ads for a small payment. The option is available from the menu in the action bar. Whatever you choose, it will help us in further development of B1 File Manager. Thank you! - Regards, Adam Buyer

NOTE: Due to changes in Google’s policy, B1 File Manager and B1 Free Archiver have no permission to write to an external SD card. A workaround can be found here: http://blog.b1.org/sandbox-an-easier-work-with-sd-card-in-kitkat/
