If you have ever tried to open old PowerPoint files in Office 2007 or Office 2010, you know how awkwardly disappointing it can get. There are chances that you won’t be able to open the old PowerPoint presentation (that was created using Microsoft Office 2003 or Microsoft Office 2000) and you will be shown any of the following error messages:
PowerPoint can’t open the type of the file represented by [Filename]
PowerPoint can’t read [filename]
Now how do you know whether the file in question is really corrupt or whether Microsoft Office 2007 is not able to open the old PowerPoint format? Head over to these two support threads and read Microsoft’s explanation on how you should apply registry fixes or update your Windows service pack to open the old ppt file in a more recent version of Microsoft Office.
The reason old PowerPoint documents wont open in Microsoft Office 2007 is that Microsoft has seldom disabled support for many old file formats. Moreover, you can’t open PowerPoint files In Office 2007, created in Office 95 or earlier versions.
Does that mean you have to downgrade your current office installation to a previous version of Microsoft office? Certainly not.
Thankfully, the superb online file converter website Zamzar has introduced a quick fix to the above problem. Now you can upload old ppt files to the Zamzar website and it will automatically convert it to a format which is compatible with recent versions of Microsoft Office e.g Office 2007 and Office 2011.
To make sure the conversion is right, remember to select the output format as “ppt(1997-2003) in step 2, an example is shown below:
The best thing about Zamzar is that it supports batch processing in the background, so you won’t have to wait for the conversion to happen. You can upload a bunch of documents to the Zamzar website and just forget about it. When the conversion is complete, Zamzar will email you the download link of the converted file to your inbox. Personally, I prefer using Google Docs for any file conversions but I am not sure whether Google Docs can handle old PowerPoint formats as seamlessly as Zamzar does.
Zamzar is free to use, requires no sign ups and you don’t have to download or install anything on your computer.
