Usually nothing. The file extension (the .jpeg, .exe, .png, .mov, etc.) tells what kind of file it is. Certain programs deal with certain extensions, like word with .doc, .rtf, and .txt. Paint and photoshop deal with .jpeg, .png, .gif, and .bmp. Powerpoint deals with .ppt, and so on. Hope this helps!

No part. The file extension (or suffix) can be used for this purpose, however there's no guarantee the file's extension matches the file's type and it won't tell you which application created the file. For instance, JPG files can be created by any image editing application, but the extension alone won't tell you which specific image editor created the file. And if you change a file's extension this won't change the file's type. A JPG is still a JPG even if you give it a BMP extension.

File extensions are typically used to associate file types with specific applications and to sort files by type. However, the actual type can only be determined by opening the file itself and examining the file's header if it has one. Plain text files do not have headers, but most other "documents" do, including JPGs. The header may also identify which specific application created the file.

Your e drive says it cant open file because it dont know where it came from?

The message is generally that your computer does not know what program created a specific type of file. Use Google to search the file type, for example *.jpg or *.doc That will tell you the type of program that made the file. If it is a video file or image file, you can find free programs which will open most of these. Once you know the program, right-click the file and see if you have that program loaded on your PC. If you do, highlight the program name and choose "Always use this program to open similar type files". Click OK.
