I typically use Google Drive and some other tools that are included such as Google Slides, Google Docs, and Google Sheets.
I mostly use it for sharing documents at work. For example, in my team, we want to share all templates on the documents we need to create. We also share pictures that we might use for marketing. Personally, I save all the documents of my project as I work on them, sometimes from home, sometimes at work, and I need to access them from everywhere. I have some projects in some folders and I save all of my documents in my Google Drive.
I mainly use it for everything related to the saving and sharing of documentation.
