Go to the Dropbox website(Opens in a new window), and at the main screen, click Create new file. You can then select between Microsoft and Google file types.

If you select Microsoft Word from the drop-down menu, Dropbox hooks you into the free online version of Word where you can now create your document using all of Word’s tools, features, and commands.

Name the document by clicking on the default title at the top of the page and typing the new name. After you name your document, the file is automatically saved to Dropbox. Once you complete the document and want to close it, click the link at the top to Save and return to Dropbox.

Click Microsoft Excel, and Dropbox links you to the web-based edition of the program. Create your spreadsheet, and remember to give it a different name to automatically save it.

By default, a document is saved in the root folder of Dropbox.

At this point, a message may pop up asking if you want to associate this type of file with its Office app. This means that any Word, Excel, or PowerPoint file you launch in Dropbox will automatically open with its corresponding Office app.

To do this, click the button for Yes, set as default. Otherwise, click the Not now button. Make any needed changes or edits in the file you opened and then click Save and return to Dropbox to close it.

If you choose one of Google’s apps you may need to sign in with your Google account to continue. At the Google Docs screen, create your document.
