open my pictures and then click tools and then select folder options then switch to view tabs and then select the checkbox which states "hide extensions for known file types"and then click ok. this should solve your problem.

actually, the files normally have an extension which like .exe, .doc etc. which define their function and filetypes have no use if they loose their extension. if you retain their extension and only exchange their name then you won't get this message

those are file extensions. so when you are renaming it don't change that part

like "name1.jpg" to "newname.jpg"

don't change the part after the "."|||Most of the files have an extension. The extension simply attaches the file with a particular type of opener application - for example, a .doc extension can either be opened by MS Word or the free program of Windows, Wordpad. In Windows, the extension is not shown by default. This can be changed from the Tools ->Folder Options -> View tab-> Hide Extension for known file types check box. This is on by default, so you don't get the extension visible. I suppose someone (including you, probably and unwillingly) has changed this setting. So whenever you are changing the name of a file, the extension is deleted. Apply either of the remedies:-

1. Just put the check box on, and rename your files without worry, windows will handle the extension.

2. Alternatively, rename the files with the proper extension (recommended).

Oh, for the files which have been renamed already and not opening, rename it once again - this time with proper extension.
