It looks like Dropbox has it's hands full now that Google is in the file storage business starting today. If you have a Gmail account, you already have a Google Docs account.
You can upload files up to 100 MB each with a total free storage of 1 GB and the ability to purchase more at these rates:
- 20 GB - $5/yr
- 80 GB - $20/yr
- 200 GB - $50/yr
- 400 GB - $100/yr
You can simply store the uploaded file in Google Docs, or convert it to Google Docs format so you can later edit it online. To store the file without converting it, make sure you deselect the option to convert the file. If you'd like to convert your document, presentation or spreadsheet to Google Docs format, you don't need to take any extra steps.
