I have .doc file on my hard drive. I want to open this document in Google Docs. But if there is no Google account, can I handle it ? And is there any solution to open .doc file without MS Office ?
You need a google account to upload the .doc file so it can be viewed (or converted to a Google Document and edited). Other ways to view it might be to use a different word processor like AbiWord (open source and can work with .doc files)
