So on Windows there is a limit for how long paths can get and rclone circumvents that by default. In my use case, this limit has to be respected at all costs. I modified the conf file according to the documentation and the limit is indeed respected.
One thing I would wish, though, is that the error message in the log could be changed to signify that this limit is responsible for the failed transfers. Currently the log says "The system could not find the path". The message is displayed in my language so I assume this is a standard error message from the OS.
Implementing a different error message would help to make the log clearer and differentiate between path limit errors and other errors that cause the aforementioned OS warning.
I hope my post is clear enough. If not, feel free to ask!
