When using all the different computing devices available to us nowadays we constantly access, edit and create files. We can easily notice that we have a working set of files which are the most important and most intensively used. Often, we want these files to be accessible in different devices and places but it is difficult to keep the files synchronized and up to date everywhere. To make synchronization of files between different devices easier a new set of services has been arising. We call these services Working Set Dissemination Services. Bolt is our project aiming at implementing a Working Set Dissemination Service.
