To use the Google Docs Uploader, launch the app and click on the File menu. Once the file opens, you can drag and drop it to the document's location in the Google Drive. If you are using an older browser, select the Files option from the drop-down menu and choose a file. The uploaded document will then appear in the Documents List. You can then edit and save the document. If you wish, you can also download the app and install it on your computer.
The Google Docs Uploader supports all file formats, except PDF. This application is more of a sample of the Google Docs API and can be useful when uploading large numbers of files. In addition, it provides a context menu option to "Send to DOCX" for files in Windows Explorer. Once you have installed the app, you can then open the files in the Google Docs application. You can then use the Google Docs Uploader to add the files to your Google Drive account.
If you're using a computer with Internet access, the Google Docs Uploader will automatically detect the files. Simply open the file, specify the src and click OK. The file will now be uploaded. If the file is a PDF, it will open in a browser window. When done, the file will appear in your Google Drive. Once you have uploaded it, you can edit it on the Web.
