I like that it's easy to use, has many features for organizing files in folders etc., but also allows you access via mobile device as well which makes things easier when working from home or traveling! Nothing really - just make sure this software meets your needs before purchasing/using (i'm not affiliated with them).
Accessibility of my work documents while at remote locations without having an actual physical copy saved locally; ability to view all versions within one folder so if there are any changes made they can be reviewed easily by multiple people who need different levels of permissions / security privileges regarding those particular items.;.
