B1 File Manager and Archiver

Overview: B1 File Manager is a full-featured and free file explorer with support for most popular cloud storage, networks and archives.

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 Googlea??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/

B1 file manager

Finally/! A file manager not cluttered with icons and unnecessary pictures. Speedy too.

Does a lot for a free app. Use in both 10" Lenovo tab and an older Sony phone.

Does what it says but what is the use?

It is a good app. It works as it claims however navigation style isn't so good compared to ES File manager, and also when you use the sandbox function to paste files onto ext SD the phone doesn't see these files as on ext SD but rather counts it as part if the internal load so you get constant memory warnings telling you that internal is full. The app helps, but is entirely hindered by this fact because the device still reads it as filling up phone memory so you might as well not use it . More work? Please?

Brian Connolly

Essential if you want a jailbreak workaround

Awesome app. Takes a few minutes to get your head around it. Essentially I doubled the storage I get on my tablet for free.

Phanat Sae

Sandbox on SD or External?

Which of the following files do I move my things into for it to go into my external SD? 4 stars for now until I get the answer.

I can now move my ShowBox movies to my SD card in KitKat.

It worked on a Lenovo s850 then stopped

It worked on the Lenovo tablet for one day, and when I rebooted the system, it would no longer transfer any files from the download folder on the tablet to the micro SD card.
