Which of the following file types is most likely to contain text? (there may be more than one correct answer)
There are many different file types, each used to contain different types of data. A file type is identified by its extension - the part of the file name that comes at the end, after a period. In the example below, each file has the same name, but is of a different type.
myfile.pdf
myfile.jpg
myfile.mp4
myfile.txt
Both A and D are correct.
PDF is Portable Document Format, and is used to convert written documents into read-only versions for distribution. TXT means this is a text file. The other file types in the question are JPEG, for photographs, and MP4, for videos.
