External file

An external file is an independent data or resource storage unit held outside of the main program or application, accessible through designated input/output operations. These files can extend the capabilities and storage capacity of the program, enabling the management and use of data separate from the executable code.

What does External file mean?

An external file, also known as a linked file or auxiliary file, is a computer file that is not stored within the main executable file of a software application. External files are typically used to Store data or resources that are needed by the software application but are not essential for its operation. This allows the software application to be smaller and more efficient, and it also makes it easier to update and maintain the data or resources.

External files are typically stored in a separate directory or folder from the main executable file. This helps to keep the software application organized and makes it easier to find and access the external files. External files can have any file extension, but they are typically named with a descriptive extension that indicates their purpose. For example, an external file that stores data might have the extension “.dat”, while an external file that stores images might have the extension “.JPG“.

Applications

External files are used in a wide variety of software applications, including:

  • Databases: External files are used to store data in databases. This allows the data to be easily accessed and updated by the database software, and it also makes it easier to back up and restore the data.
  • Spreadsheets: External files are used to store data in spreadsheets. This allows the data to be easily manipulated and analyzed by the spreadsheet software, and it also makes it easier to Share the data with others.
  • Word processors: External files are used to store documents in word processors. This allows the documents to be easily edited and formatted by the word processor software, and it also makes it easier to share the documents with others.
  • Presentation software: External files are used to store presentations in presentation software. This allows the presentations to be easily created and delivered by the presentation software, and it also makes it easier to share the presentations with others.

History

The concept of external files has been around for as long as computers have been used to store data. In the early days of computing, external files were stored on punch cards or Magnetic tape. As computing technology developed, external files were stored on floppy disks, hard drives, and optical discs.

Today, external files are typically stored on hard drives or solid-state drives. This allows for fast access to the data and makes it easy to back up and restore the data.

The use of external files has become increasingly important in Recent years as software applications have become more complex and data-intensive. External files allow software applications to be smaller and more efficient, and they also make it easier to update and maintain the data or resources.
