Just started using Syncthings and it’s great
Doing a lot of testing before go live
I have a Samsung S23U phone where I save some files in a directory, so I created a folder in Syncthing as Send only. All other things are defaults (Except File pull order which is Newest First). File Versioning is set to None.
On my computer, Syncthing has a folder which is Receive only. It works great and it watches for any changes (new files that I add) and syncs them over. Perfect.
My problem: When I delete the files from my phone it deletes them on my PC too. I tried so many configurations mainly the ignoreDelete in Advanced configuration. It still deletes everything from the folder on my computer when I delete them on my mobile. How do I prevent this from happening? What am I doing wrong?
This needs to be set on the device which receives files, not the one that sends them. In your case, you need to enable the setting on the PC. Please also make sure you read up https://docs.syncthing.net/advanced/folder-ignoredelete to understand any potential caveats of this specific setting which is normally not recommended.
Thanks for the reply. Sorry, If I didn’t mention clearly. I’ve set this on the device which receives the files so that is my PC. I verified the .stignore file and the parameter is there. I also read the docs is how I found out about the ignoredelete.
That’s not where you set it . Please clear out the whole .stignore file and then in the Web GUI, go to Actions → Advanced → Folders → your folder in question and tick “ignorePatterns” there.
