Very likely you have office Documents or someone will send you an Office document. If you are a Google Drive user you might want to utilize your Office Documents in Google Drive.
When you upload the file into Google Drive the file type remains the same. The files are NOT converted to Google Docs. Notice in the screenshot below the P symbol indicating a file in my Google Drive is a PowerPoint file. The yellow rectangle is the Google Slides symbol which is showing me PowerPoint files that I converted to Google Slides files.
Double click on the Office file to launch it in Quick Office. This allows you to edit the Office document and retain the file as an Office file. Notice the favicon on the tab shows the “Office” symbol and the icon in the upper left of the document is not the Google Doc icon, but rather the “Office” symbol.
Editing capabilities are limited when the document is not converted. Essentially you are only able to edit the text.
Sharing capabilities are restricted on an Office document as well. If you are wanting to collaborate on your Office documents you will need to either convert the Office document to a Google document or utilize Microsoft’s cloud service “Office 365” in “OneDrive.”
To convert the Office document to a Google document first open the file from Google Drive.
Creates a Copy
Saving as Google Docs does not change the Office document. A COPY of the document is created as a Google document. You can find both files in Google Drive.
