I have a Powerpoint document in old (ppt) format. Version control is enabled. I need to change the file format to the new (pptx) format. I use Save As i Powerpoint and add the new file using New Version in PP. I also have to change the file type in PP from "MS Powerpoint" to "MS Powerpoint 2007 presentation" (Which should not be necessary!)
Now things seem ok, but I can no longer open the old versions of the document because PP believes they are in the new file format. The old versions should keep their original names (or extensions), or PP should have a file type for each version.
The reason for changing the file format is that we need to use new features of Powerpont that require the new format. So from a certain version number of the document the file format will be different. We still want to be able to open the older versions, of course, but that is not possible.
I guess the same problem applies to Word, Excel, and other document types as well.

Hi,
Steps to reproduce:
1. Add a PowerPoint 2003 presentation, “Test.ppt” in a Projectplace folder with version control.
2. Open the presentation in PowerPoint 2007 or newer and save the presentation in the new format using Save As: “Test.pptx”.
3. In Projectplace, select “New version” for the document added in step 1. Select the “Test.pptx” file. Also rename the Projectplace document from “Test.ppt” to “Test.pptx to make it match the actual file.
4. In Projectplace, select “Properties”, change file type from “MS PowerPoint” to “MS PowerPoint 2007 presentation”. If you don’t do this the file will still be opened as a ppt file. This is because Projectplace seems to add an extension to the file if the current extension doesn’t match the file type. (In this case Projectplace would name the file “Test.pptx.ppt” when it is opened.)
5. Now when I try to open the first version of the document (in old file format), I first get this message from PowerPoint:
6.

If I try Repair I get this message:

Hi Olav,
Thanks for your feedback. It is unfortunate that the compatibility between versions of power point is so bad. I assume that this is the original reason for changing the file type?
I can't see a practical way for us to keep file types when using version control. That would mean that we would only take into consideration the name of the file and thus if you drag and drop for instance an image to a project with the same name as an existing document, the image would become the latest version of the document. I believe that this would create problems.
If you let me know the original reason for changing the file type, I might be able to find a better solution for you.
Best regards
Karolina
