How do I find out What program can correctly open this file?

[JaBaxter]

I have a ppt file up on SharePoint. This file was edited with MS Powerpoint 2003, saved on a CD, then from the CD uploaded onto SharePoint. My users are trying to open this file in Power Point 2007 and it will not open.

The error I receive is simple: PowerPoint can't open this file : "location"

If I click on Show Help, this is what i get:

The selected file does not appear to be a valid Microsoft Office PowerPoint file. It might be another kind of Microsoft Office System file or a file created by using a different program.

Try double-clicking the file in Windows Explorer to see if another program will open it. If PowerPoint opens again when you double-click the file in Windows Explorer, it is possible that the file is not a PowerPoint file but that its extension was renamed to be that of a registered PowerPoint file type (such as .ppt, .pptx, .pps, .ppsx, .pptx, .pot, or .potx) but the file is not a PowerPoint file.

To determine which program can open the file, try any of the following:

Contact the original author (if known) to find out which program was used to create this file. Then rename the file with the correct extension so that it can be opened by that program.

Try opening the file in other programs.

If you, or someone you know, are very knowledgeable about software, examine the file header in a text editor to determine which program can read the file.

Another possibility is that the file was damaged during transfer from another computer. If the file was transmitted over a modem, try re-transmitting the file.

Lastly, the file might have become corrupted and it needs ppt repair. If you have a backup copy of the file, use it. It is not currently possible to reverse file corruption.

Now, I have tried to look at the headers, but I am not really sure what all I am looking for.

My questions is:

How do I find out if this file is really corrupt ( there are several ppt files that will not open, all from the same location)

How do I find out what program should open this file? ( I'm wondering if this was renamed to a ppt)

Thanks guys

Hi @JaBaxter

Welcome to the HP Support forum

PowerPoint 2007 can open 2003 format and previous [known as 97-2003] without problems. The fact that it cannot be opens is because the file is corrupted - it was corrupted initially, was not correctly burned to the CD/DVD or was not successfully uploaded on the SharePoint site.

Try working with the original file to see if it opens. Try using USB pendrive to transfer the file.
