With the emergence of the cloud computing cloud storages services become very popular along with others cloud based services used by both companies and end users. Cloud storage service allow users to store their data in the cloud without any additional software or hardware. Today, users have several cloud storage account for different purposes. They may have multiple accounts taking advantages of the free storage or pricing offer by service providers; others might be concern about quality of services like reliability data security and confidentiality. The goal of managing those multiple accounts becomes a tedious task. Users with multiple accounts cannot keep track of all their files on the cloud each provider requiring login and no transfer option from one cloud to another without additional download and upload steps.

In this paper we proposed a system so called cloud storage aggregator to address this problem. Our system will allow users to connect manage their multiple cloud storage account on a single and friendly interface and provide basic file management functions. Experiments was conducted using system usability scale (SUS) method. The results showed that our system is helpful to manage multiple cloud storage accounts and easy to use.
