Backblaze B2

Backblaze B2 Mac app

CloudMounter allows you to connect Backblaze B2 cloud storage to your computer as a local drive. No need for synchronization or copying cloud files on your hard drive - manage your documents directly on your B2 сloud account with our software.

Several connections

Any number of Backblaze cloud storage accounts can be mounted in Finder at the same time, thanks to CloudMounter. Move files among B2 storages in an easy manner without having to save data on your machine.

Bridges between cloud storages

With our ultimate cloud manager, you can move and copy files among your cloud accounts without having to save anything to your computer. It is very convenient to transfer your files among different storages, including the Backblaze B2 cloud.
Integrate with Finder
Work with all mounted storages conveniently through Finder. With CloudMounter, you can access and edit files even if you don’t have the Internet connection. Thanks to the offline mode, you can continue working with your files without interruption and synchronize your changes with cloud storage once your Internet connection is stable again.

First choice for many users

It is no wonder CloudMounter is popular among users. It is a high-quality, steady product that respects your privacy and supports an impressive number of cloud storages and web services. We are always implementing new ideas to produce a steady flow of desired updates.

Use Keychain for extra security

CloudMounter values your privacy just as much as you do. It doesn't store any login data that you use for your cloud accounts - everything is kept in macOS Keychain and is sent to designated accounts via encrypted channels.

Finder Integration

CloudMounter smoothly integrates its capabilities with macOS Finder to offer you a comfortable and efficient workspace.

More Cloud Storages

We never stop generating new ideas. And as soon as the new cloud is supported or we get to add more cool features - a new version is to be released.

All supported services

CloudMounter supports B2 cloud storage and lets you mount other cloud storages as drives such as Google Drive, Dropbox, Box, OneDrive, Amazon S3, MEGA, etc. Besides that, the app also works with FTP/SFTP/FTPS/FTPES and WebDAV servers.

Safe Access to Cloud Storages and Web Services

With CloudMounter, you can be sure your important files stored in the clouds are all safe. You can encrypt data in Google Drive, OneDrive, Dropbox, Amazon S3, FTP/SFTP/WebDAV servers, as well as other supported services.

    I’ve regularly used ExpanDrive and the native Mac client from Google, until recently. CloudMounter is simply the best of both worlds.
