Can I use web-a-file from multiple computers?

Yes. You can use the Web-a-File services from as many computers as you wish. The only conditions are an Internet connection and a web browser. For more advanced features such as scheduled backups you will need to download and install the Web-a-File client software available at www.web-a-file.com

Also, you have to make sure that you keep track of file names, trees and directories. It may become confusing if you have same name directories and files in multiple computers with a different content.
