You would need a custom function to sort a list of values - I believe there are some suggestions at Brian Dunning's site.
However, IIUC you don't really need to sort the list - you only need to find the minimum value. This could be done this way =
Let ( [ f = "Min (" & Substitute ( listOfValues ; [".MyApp_Data.fp7" ; "" ] ; [ ¶ ; ";" ] ) & ")" ] ; Evaluate ( f ) & ".MyApp_Data.fp7" )
Note: using a period in a file name is NOT recommended.
Thanks. I'll try this out. Also, I've heard that some shun using a period on a filename the way I did in this thread, but never knew why. Why is that?
Ah, yes. I know about Get(FileName) not grabbing the extension of a file. Thanks.
