I'm working on the next major version - and *hopefully* it will allow you to log an unlimited amount of data to the same file. It won't load the data from the file until you want to look at data for that time period (in 2.0x, it loads ALL the data into memory - so this makes large files a problem).<br><br>Hopefully, this will allow someone to have all the data for a specific site in the same file - and then be able to look at pictures or export data from pertinent time periods to send to others or analyze in other packages.<br><br>Is there any reason you'd still want to save multiple files for the same destination? <br><br>Thanks,<br>Pete<p>
