There is an easy way to convert all of the docs over, without doing them individually.

1. Copy all the documents to be converted to a single folder.

2. Click on the first file in the list.

3. Holding the shift key, click on the last file in the list. This will select all the files.

4. Right click any file in the selection and from the menu select "open with..."

5. Select Open Office writer. This should open the selected files as Open Office files.

6. Save the files from Open office in the format of your choice or export them as PDF files.

7. When the transform is successful, delete the original MS .DOC files.

Actually, there is no need to convert from MS *.doc format, since OpenOffice/LibreOffice can read all but the latest from MS without conversion (although you will see some weird formating changes, figures jumping around a bit, etc.). Open the *.doc document in OpenOffice, clean up the formating a bit, and save it as *.odt. Also works for Excel files and PowerPoint. You can not go the other way- if you want someone to read your OpenOffice document with an MS product, you have to save it as such (which OpenOffice also permits...)
