a string representing
the name of the file for which the creation or modification date needs
to be retrieved; this can be specified as a fixed string, field name,
or expression.
Optional Argument
datetype
a Boolean that specifies
whether the creation date or the modification date needs to be returned;
this can be specified as a fixed string, field name, or expression
[true = modification date, false = creation date].
Details
The FILEDATE function
returns either the creation date or the most recent modification date
of a file. If the file does not exist a (null) value is returned.
If the argument DATETYPE is omitted, the function behaves like the
value would have been specified as false.
Example
string filename
date creation_date
date modification_date
filename="C:\mydata.txt"
modification_date = filedate(filename, true)
creation_date = filedate(filename, false)
