What indicates the last time a computer file was saved or created?

The most appropriate term to indicate the last time a computer file was saved or created is the Modification Date. This date reflects the most recent moment when the file content was changed, regardless of whether it was the first time the file was saved or an update to an existing file. The Modification Date is updated each time the file is edited and saved, allowing users to track changes and determine the most current version of the file.

The other options present different aspects of file timestamps. The Access Date refers to the last time a file was opened or accessed, not necessarily when it was modified. The Creation Timestamp gives information about when the file was originally created, but does not reflect any subsequent changes. Lastly, Last Edited can be an informal term similar to Modification Date but is less standard and may not always be used in the same context across all file systems.
