Final answer:
To finish file access in programming, the 'close()' command is typically used to ensure that the file is properly closed and system resources are released.
Step-by-step explanation:
When you are finished accessing a file referred to as 'theFile', it is essential to ensure that the file is properly closed to prevent any potential data loss or corruption. In many programming languages, this is done by executing a command that closes the file and releases any system resources associated with it.
For example, in Python, you would use the close() method associated with the file object like so:
theFile.close()
In other programming languages, the command might differ, but the concept is the same. It's crucial to check the documentation for the specific language you're working in to find the correct syntax for closing a file.
