DO NOT USE THIS TAG TO ASK FOR SERVICE RECOMMENDATIONS
Online storage is also known as cloud storage.
If there is a specific tag, for the web application, use the corresponding one instead of this one. Most web applications include the online storage of the content handled by the app, like gmail and google-photos. Home, school and office productive suites, including word processors, spreadsheets and presentation applications among others, might have a companion file management application. In the case of Microsoft Office it's OneDrive, in the case of Google Editors it's Google Drive.
Some online storage services might be installable. Questions that are specific about the installable software or might require knowledge about the operative system and other required components are off-topic.
