Opening a PowerPoint presentation fails with error "invalid path or file name".
Whenyou go to a Document Library and try to open the presentation, PowerPoint opens, but then you get the error "The path or file name for "file URL" is invalid. Please check that the path and file name are correct."I installed MOSS/WSS SP2 about 2 weeks ago, this happened once or twice before then, but I now know of about a half-dozen presentations that won't open.There is a way to get the file to open, if you hit the drop-down next to the file and select Send To and Download a Copy, you can save or open it from there.If you try browsing to if from within PowerPoint, it won't open either, and will also not open in Explorer View. We have replaced the file, saved as a different name, etc. with no luck.Using both IE 7 and IE 8 and both XP Pro and Vista Business workstations.Any ideas out there?Thanks,Rusty

Ah yes, but which versions of PowerPoint are in use ? - when creating the files stored in the doc lib - on the client PCs used to access the MOSS systemWSS FAQ sites: http://wssv2faq.mindsharp.com and http://wssv3faq.mindsharp.com Total list of WSS 3.0 / MOSS 2007 Books (including foreign language) http://wssv3faq.mindsharp.com/Lists/v3%20WSS%20FAQ/V%20Books.aspx

Dang it, I had that in there and must have deleted it on an edit.Everything was created in and being accessed by PowerPoint 2007. Most presentations were saved in "Compatibility Mode 97-2003" (.ppt), although at least one that won't open is native 2007 (.pptx).

This sounds like the behavior you would see if the file name, including its path, is too long. "too long" is a weird number, like 180 characters or something. OTOH, I would expect that to prevent you from downloading it locally if that were the case.--Paul Galvin, Arcovis Microsoft MVP - SharePoint Blogging @ http://feeds.feedburner.com/PaulGalvinsSharePointSpace Twitter @ http://www.twitter.com/pagalvin

Hi, Can you open the file on SharePoint successfully for the first time? If the symptom happens when you open the file the second time and you receive the following error message: The path or file name for 'https://server_nameSPSsite/documents/file_name.pot'. is invalid. Please check that the path and file name are correct. I think this hotfix from the article KB949405 can help you. Let me know if I misunderstand you.Xue-Mei Chang

Yes, I did confirm that they are in Designer SP2 which I have installed. Although when I search for any of the three files in the Hotfix, I can't find them on my workstation.Also, how would this affect my MOSS server?

Hello, I was wondering if anyone was able to find a solution to this problem since the exact same problem has occurred on our MOSS 2007 server over the last couple of weeks. The only way that I've found to "fix" it is to reboot the server. Looking forward to any help on this one!!

Check the name of one of its parent folders. I think the problem is a result of having special characters in the folder name. I had the same error so I deleted the original pptx file and uploaded a brand new pptx file. Didn't work. But then I noticed the folder it was in had a plus sign as part of the name. The actual path to the file was "Site > Shared Documents > Project Management > Sprints 1+ Project Management". I edited the properties of the "Sprints 1+ Project Management" folder and removed the plus sign. I was then able to open my pptx file. Just to verify, I went back and put the plus sign back in the folder name and sure enough I got that error again.

I am having the same problems with IE 8. Using Firefox without any problems, but the DoD doesn't like FF. Is there a solution to this problem? Is there an IE patch?Greg Appelt

Hello, I'm facing the same problem with several kinds of filetypes. It affects office documents as well as pdf files, but only some of them. I read many many articles today and I'm not sure, if this is really a client problem. When the error occurs, the file isn't reachable from any client and, as swissalps mentioned: "The only way that I've found to "fix" it is to reboot the server." This experience i made as well. Unfortunately I found no hint or error message in any of the serverlogs. A server reboot fixes the problem for some weeks but i want to get rid of it! Did anyone look at this issue successfully from the server point of view? Thanks, Stefan [Windows Server 2003, WSS 3.0 fully patched]

I am having the same problem. It appears to have more to do with file size than type of file. Just happens that the power points are the biggest files.

This issue seems to be associated when you create a new Document Library. If you click on the New button, you get the error. I have managed to get this resolved by doing the following: 1. Go into the Document Library you created. 2. Click on Settings > Document Library Settings. 3. In the Settings page, click on Advanced Settings. 4. In the Document Library Advanced Settings, click on Edit Template. 5. Once the document opens up, edit it as desired and save it. Once you have done the above steps, go back to the document library and click on New. The document should open up with no issues. I have also tried to replace the document template using SharePoint Designer 2007 and I still get the error. Using the steps above is the only way I am able to successfully create the template I need with no error opening up. Hope this helps.
