That was quick and most excellent work, a million thanks!!! Saved me hours and hours for sure. Hopefully will be useful to others.
I think I managed to relocate everything, maybe needing to make 15 or so top-level substitutions.
For the benefit of others and for development feedback, some
random observations:
• I could select
any torrent located anywhere within a path I wanted to change, and search and replace the highest folder level common to many torrents (as I wanted to be able to do).
• but that really does seem "powerful"
[as in big chance for OOPS.] make a backup first.
• given that, I wondered if it made any difference at all
which torrent I selected? Could I not just select a random one and do whatever search and replace I wanted on any arbitrary paths?
• Shift allowed me to select "relocate" from context menu even when there were multiple selections in the torrent list. (and it's easy to unintentionally make selections.) To be safe, I always made sure i only had one selected.
• there were a couple interface glitches relating to editing the paths and then the "substitute" dialog just disappeared
en medias res.
• after finishing, it was helpful to go to Session > Shift > Scrape Paths to eyeball all the paths were changed correctly.
• what the green "move" radio button did was unclear as there is also both a "relocate" button next to the "substitue" button. (Perhaps this is an artifact from the previous version.) I was able to use the Substitute button even with "move" still selected (as it is by default)
• I presume that "relocate" would actually move files and so I didn't touch that (having already mirrored my files to new locations on a new NAS)
Questions:
• how do I reset the environment to use the default WebUI again (not that I'm likely to -- Shift is great -- but still couldn't figure that out.
• returning to possibility to run transmission on a the (Synology) NAS (in a container), presumably, I could run Shift there just as well, right?
• and a bit off topic but in case you know: earlier you mentioned i could copy the torrent & resume files to specific locations (on the NAS). Any idea where those might be? And how to set the environment there? Or any references?
