When trying to save a document in Word I go to "Save As" and select the folder I want to save it but only some of the files are there. When I look in Explore at the same folder there are lots more most of them are word documents. They were produced on an older version of Word. Would this be why they son't appear when I try to "Save as". If so how do I resolve the problem if n ot help regards
As explained above, if you are using a newer version of Word, as standard it saves documents in a new format - docx - instead of the older doc format.
This doesn't give you any problems - your new version of Word will open the old documents as well as the new ones.
You don't need a compatibility pack - that is for older versions of Word to handle the new document type. That's not your situation.
If you wish, you can save documents in the old .doc format - just choose that type when you do a "Save as" - you'll see the chance to do that at the bottom of the window that opens when you click "Save as".
