file types

Extensions like PDF

File types categorize digital files by their format and the kind of data they contain, typically indicated by an extension after the filename—.pdf for documents, .jpg for images, .mp3 for audio.

The file type determines which programs can open and interpret the file correctly.

My email rejected the attachment because it doesn't allow executable file types.

Understanding file types helps users choose appropriate formats for compatibility, quality, and file size.
