Bill, Yes - that is correct. I do have a long file name (in which the date and time is embedded into its name), so I cannot change the naming of the files as I need it to show up in the description or filename of the time lapse. So... I need to sort on the actual time and date of the image - NOT the filename. (I know I could simply use another program (batch rename or something) so rename the files after sorting them correctly by the file date and time, but then the file name (which has the date and file in the file name) would not be correct and I could not display it right. That means I have to have PTE sort the files by the actual date/time that the time lapse was taken in order to get it right. Another example is that I sometimes shoot events where all the digital cameras on the project are syncronized with the date and time . When all the photos are downloaded into one big file folder (no matter what the camera), the pictures can then be sorted by time/date so that they all tell the story (as in a "day in the life of" type of event. So, it is important that PTE be able to do this (like most programs do) so that the slides are in order - no matter what the file name is called. I THINK that this should be a "simple" tweak to get PTE to do this right. Doug.
