LittleFS data upload removes other files.

Hi, when uploading to an ESP32, I include a data folder (using auto-upload via LittleFS).
But I also create and update a file within the ESP32, also using LittleFS. This file gets deleted on every upload (not on reboot).
All this happens in the root folder on the ESP32.
Is there a way to upload without deleting existing files?
Thanks in advance,
Erik.

If you follow the guide in yellow above we will see the littleFS command and how it works. It will be a question for the author of littleFS but there might already be a switch you can pass that preserves existing data. 

Seeing the verbose command will give us some pointers as to who you need to ask or what to look for.

Tnx. So I understand that you didn't build the upload tool yourself.
I found the actual tool and it appears it creates a local 'disk-image' of all the files and then uploads that image (a single file) to the ESP.
That leaves me with the option of trying to create a separate and unaffected partition in the flash. Not even sure of that's possible. 
Or frequently download the user files from the ESP, via the webserver (which happens to be installed already for this particular application).
But it's just a small settings file, so I won't bother with either solution. At least I know my options now.
