Check all statements below that describe a valid way to convert a file from one format to another $($e$.$g$.,$ a Word document into a PDF$).$

Use a special piece of software that reads in file in the original format, converts it to the other format, then writes it out that way.

If your software has an export feature, you can use it to export the contents of the file in a different format $($if that format is supported by your software$).$

Usually, you can just rename the file and change it's file extension.

Files cannot be converted. A new file in the the new format must be created, modified, and maintained by another piece of software.
