| Description |
The FileAge function returns the last modified date and time of a file FileName.
There is no need to open or close the file - this function handles these operations silently for you.
The returned value is in a 32 bit partitioned format. Use the FiledateToDateTime function to convert into a manageable TDateTime value.
If the file date could not be found (for example, the FileName was invalid), then -1 is returned.
