DaveF Posted June 24, 2020 Report Share Posted June 24, 2020 I want to create a test that will determine if a file with a specific name exists. Will the SD File Read Open return a file size of 0 when attempting to open a file that doesn't exist? Thanks! Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted June 24, 2020 MVP 2023 Report Share Posted June 24, 2020 Not sure without trying a mockup, which I can't do at present. I know SD File info will let you do what you want. Also allow that anything SD is a bit slower than you might expect. Don't rely on something to change in a single scan. cheers, Aus Link to comment Share on other sites More sharing options...
DaveF Posted June 25, 2020 Author Report Share Posted June 25, 2020 Not sure if this matters to anyone else but Support recently responded to my inquiry. In this case SI67 is updated. I am able to make an event trigger on that. Thanks! Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted June 25, 2020 MVP 2023 Report Share Posted June 25, 2020 That's good. Just so you know, this table is lifted from the Help file under SD Cards. There is a wealth of information there, but nothing beats physically trialling something. cheers, Aus Link to comment Share on other sites More sharing options...
