Because I use Syncthing and Resilio in parallel, for the Ignore lists I use as follow:
Including in Syncthing Ignorelist:
// Resilio .sync .syncID .syncIgnore .syncArchive *.bts !sync *.syncPart *.syncTemp *.syncOld
Including in Resilio Ignorelist:
// Syncthing .stfolder .stignore .stversion .syncthing* .syncthing.* .syncthing.. ~syncthing~..tmp *.Identifier
In this way is possible to have a folder in both peer lists, if needed in special cases.
