I want to define a filter in "filters.txt" that excludes the subfolder sequence
tdata/working
because that is a part of the path from the portable Telegram application that can't be read as long as Telegram is running...
I've tried (after reading https://rclone.org/filtering/)
- tdata/working/**
and a few variations but it seems it doesn't work that way?
You are not doing anything obviously wrong I can see!
The way to test filters is with rclone ls to list the target but using the --filter-from file then you can get quick feedback as to whether it is working or not.
Also can you paste the extra bit that --dump filters --vv prints - that shows the filters as regular expressions which might give a clue.
