>Gee :) Taking into account that sys(2015) is generated using datetime, I never used that suggestion (and missed it up till now :) and instead added a char in front of whatever part I get it from sys(2015). A simple 8.3 format by sys(2015) :

lcTempFileName = stuff("T"+sys(2015),9,0,".")

That's a good suggestion, Cetin.

When I wrote 8.3, I actually meant that 8 unique chars for the "8" side. For a unique 8, it is important to take the right hand side of the return value, because that its the part of the return value that will vary the most. Case in point is the fact that the 3rd/4th position of the return value just became zero and will be for a year (not very unique, huh ;-). Think of it like 5 people with stopwatches with millisecond accuracy all pressing the stop button at the same time. For everyone to have a unique time value with 5 digits, you would want to use seconds and milliseconds, not hours and minutes.
