What is a .PPT file?
DarrenW - 3/7/13 at 08:01 AM

Ive been asked to look at some training presentations at work. Most of the files are .ppt and open great in Powerpoint (as you would expect). A couple of the files have a .PPT extension and i cant get them to open. Does anyone know of a fix for this? I assume they are still Powerpoint presentations, but ive never come across the .PPT extension before. Searched on google but i can only find info on .ppt's.

Im using a Macbook with Microsoft Office 2011 installed if that makes a difference.

I will go and ask the person who i got the slides off if they can open them on their PC while we try to suss this out.


Thanks in advance,
Darren.

PPT is still a powerpoint file, try changing to .ppt and see if they open as the others do?

Just changed one of mine to .PPT and it still opens with Powerpoint

If you have newer version try saving as a PPTX file

The suffix's aren't usually case sensitive, whether it's .ppt or .PPT it should still work the same. I don't know whether Mac's are sensitive to the difference though.

I've found that with the newer versions of Office the compatibility drops right down. I'm frequently having to go back to the author of documents to get a copy that is 2003 or 2007 compatible. And we don't use enough of the new features to warrant the newer versions, every so often we get a warning about colour changes but that's about it.

As I understand it, its actually a bit of a mess. Some file systems are case-insensitive (cant tell or differentiate) Fat32, some are case-preserving (can tell but dont differentiate) NTFS , and some are case sensitive (can tell, and care, allowing a doc1.ppt and doc1.PPT in the same directory) linx. Or something like that....

However, in principle I would say its fair to say modern domestic operating systems are at very least case-tolerant.

I dont know the history of legacy powerpoint files, and it may be that its come from an old version of the software on an old FAT32 based machine and isn't compatible with your newer software, but its not something I have come across.

Most Macs these days are Intel based PC's now anyway arnt they......


I would ask them to have a look at how they have saved them, and or, what version of powerpoint there using!

Yes, that's a better description.

To be honest, the traditional three letter extension is only for our own benefit, you can use any extension on any file (and even leave them off if you want). If you renamed the file .bob, then associated .bob with powerpoint, it would still work.

I regularly change the .csv association to work with notepad instead of Excel, mainly because Excel makes a complete hash of comma delimited files, especially those containing text.

Depending on the version of office ( powerpoint ) you have and the version it was created in you may need to look at installing a office compatibilty pack from microsoft.
