Is there a way to delete old flight logs from Litchi/flightlogs and Litchi/SDK_logs/FlightRecord on an iOS device?
The Litchi app does not appear to provide access to the flight logs. iTunes only provides a way to delete the entire flightlogs or SDK_logs folders. It it not clear how gracefully the Litchi app would handle that.
Correct, the app doesn’t provide a way to manage those from within itself, but it is safe to delete both folders manually (do it while Litchi is closed, since a log file stays open during flight):
“flightlogs” contains Litchi’s own flight logs (CSV). Litchi only ever writes new logs there and recreates the folder automatically on your next flight, so deleting individual files or the whole folder is handled gracefully. One thing to keep in mind: if you use the Airdata auto-sync, logs deleted before they were synced can’t be uploaded later, so back up anything you may want to keep.
“SDK_logs” (including FlightRecord) is created by DJI’s SDK, not by Litchi. Those are DJI’s own flight records, and Litchi never reads them, so that folder can also be deleted safely and will be recreated as needed. The only reason to keep recent ones is if you might need to send flight data to DJI for a warranty or repair claim.
Thank you for letting me know that Litchi will gracefully handle this.
I do sync all of my logs to AirData. I also back them up to my computer.
Using iOS there is no way to delete individual Litchi (flight log) files. iTunes enables the deleting of top-level folders for certain apps including Litchi. Unlike DJI Fly, Litchi does not appear in the Files app. Using the Files app I can delete individual DJI Fly log files. Since Litchi does not appear in “Files”, I am unable to do the same with Litchi log files. It is unclear whether or not this is the developer’s choice.
Software like iMazing will let you browser app folders and delete individual flight logs. Something that Apple’s finder should really do by default.
Litchi does not expose its files to the Files app, this is a feature more designed for Document type apps such as excel, etc.
