Microsoft introduced the .docx file format in its new Office and Word applications and wants it to replace the commonly used doc format. The problem with the change from doc to docx is that many users are still working with prior versions of Word or no Microsoft product at all and face the problem that they can’t load the docx file because it is not supported in their application. To make matters even worse, the trial version of Word 2007 will only save in the new docx format and has the ‘Copy’ and ‘Paste’ functions disabled. Anyone who created documents in the new Word 2007 trial edition were forced to save in the new format with no chance to transfer their own information to another application. Once the trial expired, you had two choices – buy Word 2007 in order to retrieve your information or re-enter all that information once again in another application.
