Understanding File Type

File Type Checking

Choose any file on your computer. The file name may or may not have the correct file extension. It does not matter. The file type will be determined and displayed for you.

Please do not choose a large file. Uploading may fail on files too big.

Challenges

• What type is this file A? Check it.
• What type is this file B? Check it.
• What type is this file C? Check it.
• How easy is it to rename a file so its name does not have an extension such as .doc or .jpg?
