    Encryption Process

    Drive Synchronization

    Sync files and folders between devices

Encrypted Cloud Storage

XXL Cloud stands for Secure Cloud Storage. Secure means that files are encrypted when they leave a users device, and decrypted when they return back to a users device. Data is end-to-end encrypted, which means no one else than the user can access the plain text content of files stored in XXL Box. XXL Box offers Free Online Storage for all files which either need to be backed up, or safeguarded against loss.

Synchronize as many folders as you want

Synchronize any folder, and as many folders as you want, between Windows, Mac and Linux PCs. Even on mobile devices and the web you can access your files on the go. Cross synchronize between different Operating Systems. XXL Box Secure Cloud Storage is made to work the way you want! It is the only productivity tool that sets no limitation on folders or files you can store in XXL Box.


Collaborate with your friends or collegues by creating Groups either privately or publicly. This way you can exchange files privately with a set of XXL Cloud Members, or share files publicly. Collaboration features also allow to send messages to individuals or group members as well as creating Wikis.

Cloud Backup & Disaster Recovery

Backing up files and keeping them safeguarded is as important as accessing files on different devices. Backing up files to the cloud, serves also the purpose of recovering from disasters, such as Drive Failure at local servers or desktop computers. At once your valuable data is stored at 3 different geographical locations, so even in the case of a complete geographical blackout - Your data is still accessible!

‘Zero-Knowledge’ Privacy

If you choose to encrypt your data, our 'Zero-Knowledge' Privacy Policy applies. 'Zero-Knowledge' privacy means the server never knows the plaintext contents of the data it is storing. Never. Therefore, the data is never at risk of being compromised or abused by either internal threats or external hackers.

XXL Box Crypto LibrariesTM & Encryption

Files in XXL Box are end-to-end encrypted. But this is not enough; An additional layer of private encryption, so called "XXL Box Crypto Libraries" provide password protected file collections which are encrypted on a users device and decrypted when the files are opened with the password used to encrypt them. Crypto libraries can not be recovered in the case a user looses or forgets the password. XXL Box Crypto Libraries are free of charge and available even in the Basic (free) edition of XXL Box.
