Some people like to dump all their information into a single EagleFiler library, with minimal folder structure, and locate documents that they need using the search feature. But EagleFiler also supports multiple libraries, for those who like to separate their business and personal files, group them by project or client, or keep different kinds of files in different places. For example, you might keep some of your files on your iPhone or USB keychain drive, some in an encrypted library, and others in your Documents folder. Unlike with iTunes, you can have multiple EagleFiler libraries open at once. Each library can also have its own set of tags, so that you always see tags that are relevant to the task at hand. However you want to group your files, EagleFiler can accommodate.
