The FileDateTime function returns the date and time when a file was created or last modified.
Syntax
FileDateTime(pathname)| Argument | Description |
|---|---|
pathname | Full or relative path to an existing file |
Examples
FileDateTime("C:\Reports\Sales.xlsx")
ModifiedAt: FileDateTime([FilePath])The call raises an error when the file is missing or inaccessible. Validate trusted paths and handle errors; never build a filesystem path directly from untrusted input.
See Microsoft’s Access function reference for related expression functions.
