I don't know how to open the file in Windows Explorer.<<
Click on Start, then Run, insert Explorer.exe and press Enter. When explorer opens, navigate to your PowerPoint presentations. Pick any of your presentations and right click on it. When the window opens, the top item should be in bold and tell you what you can do with the presentation. If it is a .ppt file it should say Open if it a .pps file it should say Show at the bottom is the properties option. click on that and see at the bottom of the properties window the attributes for your file. If it has a checkmark in the read only box, remove it and open your presentation to see what happens.

Yeah! A new voice is heard. No, the jump drive is okay. I have made copies
and emailed copies to myself and tried on another computer. I have
reinstalled PowerPoint and restarted my computer. When I try to drag the
presentation to the jump drive there is an international no symbol on it; the
original is read only by default. I didn't choose that format. Every copy I
make is read only also. I don't know how to open the file in Windows
Explorer. Sheeesh! Thank you.
