Over the years occasionally I will open a folder to view photos and a group (sometimes as much as a third) of them will have a big X through the window box. If I try to open them I get different errors depending on the program. example: :missing marker in jpeg, program can't recognize the format, etc. any ideas folks.

Might be time to upgrade that old computer?

JPG files occasionally get corrupted. If the OS can't read the file header (first couple bytes of a file,tells the OS what kind of file it is) correctly, you get garbage. Like a big red X.

Well with windows, sometimes it forgets how to open a picture by extender, ie., .gif, jpg, tiff, etc.

What I do is right click the photo and pick ' Open With ' and from the selections, pick the photo program I want to associate with .jpg format.

Of course you won't see much if you don't have 'show common file extenders' active.

thanks Sarge, I tried your suggestion and the error message was : the file format module cannot parse the file: How do you make the common file extenders active?

Well, with Windows 7 you just click Start / Control Panel / Folder Options then click view and then take the check mark OUT of the box marked ' Hide extensions of known file type '

With some earlier versions of Windows, get to a folder on your hard drive and double click a folder. You'll see TOOLS at the top, click it and then FOLDER OPTIONS then VIEWS.
Follow the note above for taking the checkmark out.

Now when you open a folder you'll see all the FILE EXTENSIONS for files, not just the name.

PS: There is an option for 'hidden system files' I'd leave that alone.

Check the file extention - make sure that it is ".jpeg". If not, right click and rename to make ".jpeg" the extention. There are times when I have made a Windows Explorer edit and then Explorer changes the extention upon saving.

wouldn't that be .jpg not .jpeg ??

.jpg and .jpeg are the same but sometimes computers get ornery and decide that they aren't the same and thus the need to rename.

Have you edited any of those files (or batch edited a group) ??? AND perhaps mistakenly save them as another file extension such as a .psd ??

Shelter Cove, You got my curiousity going so I checked: The major difference between the JPEG and JPG is the usage of the platforms(Operating Systems). JPEG is the extension given by the Macintosh and JPG is the extension used in Windows . This was from an older article.

I do not use Mac, so perhaps a Mac guru can validate this .........

.jpg for windows systems instead of .jpeg as the Mac systems use is a throwback to the days when a three letter extension for a file was all that Microsoft operating systems could handle. Any windows system from the last decade can handle files with a extension of either .jpg or .jpeg; I have saved files both ways. In the windows world programmers still like to limit the extension to three letters-I suppose because users would think something is wrong if it were different. If you check out the file formats that your editor handles you will find the extensions of .jpg .jpe and .jpeg as valid for jpeg files
