Question about Dell Computers & Internet

1 Answer

Some of my emails have attachments that read ''Unknown File'' when I try to pull them up. I used to save them to PowerPoint and was able to pull them up there, but I don't have PowerPoint anymore. Is there some other way I can read these email attachments that say ''Unknown File''? Just so you know, I am a novice and use my desktop computer mostly for email and looking for information, so any complicated suggestions you may have will have to be in language a 76 year old can understand.

It is marked "UNKNOWN FILE" because you don't have MICROSOFT OFFICE installed in your PC to be specific MS PowerPoint is not installed, yes you can still download them from your email account but you can't open them. You have to install MS OFFICE to be able to view this files.

Powerpoint can't open the type of file represented by........


1. Try some of the things listed below. But first make a backup copy of your presentation and use it, not your original file. Never try any of these recovery techniques on your only copy of a presentation.
Things to try:
-If you run PowerPoint 2003, choose Help, About Microsoft PowerPoint from the main menu bar. If the About screen doesn't indicate that you have SP1 (Service Pack 1) or higher, you should update your copy of PowerPoint. Choose Help, Check For Updates. When the Office Downloads page opens in your browser, click "Check for Updates" and apply the recommended hotfixes and/or service packs.
-If you run Windows XP and have installed SP1, see Files open as Read-Only after installing Windows XP SP1, Other file/path related problems
-Open a blank presentation (You can apply the template used for the damaged file, if applicable. That might help cut down on reformatting.)
-From the main menu, choose Insert, Slides from File (or if you use PowerPoint 2007, Home tab, New Slides (bottom of button), Reuse Slides.
-Try to insert slides individually if you're not able to insert the whole thing
2. If your file became corrupted when PowerPoint or your computer crashed, there may be a temporary version of the file in your TEMP directory. If so, you can try the aforementioned Insert, Slides From File and browse to that file. Or you can try changing the file's extension to PPT and see if you can open it from within PowerPoint using File, Open. You could also do a search for *.TMP files on the off chance that it's not in your TEMP directory.
3. If nothing else works, try opening the presentation in Word to see if you can at least recover the text:
-Start Word and choose File, Open
-Choose file type "Recover text from any document"
-Edit the file as needed
4. If all these three methods don't work, then use third party software PowerPoint Repair Toolbox https://www.repairtoolbox.com/powerpointrepair.html

Message in Powerpoint: Part of the file is missing. How to fix it?


your powerpoint file seems to be severely corrupted. You may try to open this file in PowerPoint Fix Toolbox http://www.powerpoint.fixtoolbox.com/

If if it useless follow the steps 1) Open a new presentation and use Insert --> Slides --> From existing presentation to pull in the slides from the corrupted file. This works about 50% of the time.
2) Try using the Clone Me add-in from Microsoft. It may work, it may not.

I want to open powerpoint presentation.


then, go to format -> slide design, choose to show all documents, and choose the corrupt powerpoint file. now, go to insert -> slides from file, and select the corrupt powerpoint file. make sure you are set to insert all slides, and then import. if that works, great! i suspect, however, that you might crash at that point. if so, try repeating the process, inserting specific slides one by one until you find the problem one. after that, save the file, making sure that fast saves are off (in preferences / save).
if you are unable to open your powerpoint files then try pptx viewer tool. this utility recovers your corrupt and damaged powerpoint presentations (.ppt, .pot, .pps, pptx and ppsx formats) from ms powerpoint files. http://www.pptx.viewertool.com/

Because you must use another program to send it - like Outlook.
Just do it the correct way: save the ppt file on your pc, close PowerPoint, open your mail program (Outlook or whatever) , compose a new mail , attach the ppt file to it and send the message to its destination.

I was emailed a picture and I want to save it so I can use it in a powerpoint presentation. What extension do I need to use?


The extension will already be part of the file. If it's an emailed image, it's probably a .JPG  I don't know what program you're using to view the image, but often a right-click and 'save as' does the job.  If that doesn't work, please post details of what email program you're using (webmail?  browser?) and I or someone can give you a more detailed reply.

Any email file I receive that has a pps attachment I cannot open


Ill ask the obvious first, do you have Microsoft Powerpoint installed? If you dont, you can download a free PPS viewer. Just Google "PPS Viewer" , download and install it. If you do have PowerPoint, then try saving the pps file to your computer locally and try opening it? Please always post your questions with as much details as you can. What email client are you using? Gmail, Yahoo, Thunderbird, Outlook, Outlook Express, Windows Mail, etc. Its hard to answer questions with hardly any info. Thanks!

Cannot create an associated folder


If the email had that file attached to it properly and it was not corrupt in the file upload and download you should be able to save the file to your hardrive then open it. So look at the email if the file was attached make it download now and save it to a folder that you can remember like you desktop or my documents. After it is saved there then try to open it.

Windows mail and powerpoint viewer


From windows mail choose Options Then Security Tab. You can change some security behavior here for allowing viewing of attachements, however it will only work for certain file types. Others are prohibited regardless. IT's a measure Microsfot feels is protecting folks forcing them to save the file then open it. This allows Antivirus programs to fully scan the file before use. But it's fairly impractical.

If you get frustrated with WM, you might try Thunderbird from Mozilla.com Its free and far more flexible and robust than WM.

Good
