I am trying to set up an automatic backup of a data file in which I store data from my VI. I want to back up my data in 2 ways, first if the the file exceeds a predetermined size I want to copy it to a new directory with a date stamped name, then create a new empty data file to continue logging. This part I can do. The problem is that I also want this file to be backed up every 24 hours after its creation date. I can get the data to tell when it is created and back it up, but when I delete the old file (or move it), then create the new file it has the same creation date as it orgianlly had. I know that the file has been deleted, if I add long delays into my VI I can watch through windows and see the file disappear from my file directory, then it will be re-created and appear again. I do not think that I will have much hair left if I continue working on this much longer. But of course I am sure there is an easy answer somewhere. I have tried a reply from another thread using the external call to the touch.exe program, however it does not change the programs creation date, only its last modified date.
