What is a file type?
File types define how files and organizational data are stored in a business. A file type is usually identified by the file extension and the applications associated with the file. Each stored file can have multiple file extensions but a single file format.
A file format defines the way data is stored in a file. Since every business is dependent on storing their data in various file formats and types, it’s highly recommended that file reader software is used for a seamless file retrieval experience.

Uses of file types
Developers and organizations use different types of files to store, manage, retrieve, and use business data.
- File types are essential in identifying which applications should be used to open certain files. The associated applications can be identified from the file extensions.
- File types and extensions help developers and business stakeholders identify the file contents without actually opening them. They also help in grouping similar types of files together for easier access.
- File types can help verify a file’s trustworthiness before it’s opened. Emails containing executable (.exe) files are tagged as malicious by security teams and employees, discouraging them from opening any such links.
Basic elements of files
Every file storing organizational data has a few basic elements to make it recognizable and easily accessible for its stakeholders.
- Filename: An unique name given to a file to help identify it.
- File extension: Group of letters found after a filename, that identify the type and format of the file.
- File metadata: It stores information such as creation date, modified date, size, creator, and type of the file.

File types provide an easy way to categorize business files, and it’s necessary to have a system in place to use them optimally. Below are some essential practices that need to be followed to create a well-managed file system:
- Group files according to their file types. This makes them easily accessible.
- Use good naming conventions for files so that duplicates can be filtered out.
