File naming screwup

[Spizro]

Hi,
I'm still pretty new but I've been figuring out things as I go. I used to host all my files on G-drive but it got to expensive so I built my own NAS. 
But I made one fatal mistake. Every single file I have is named "Whatever-S01-13". Which if something only has one season, no big deal it lists it as S1 E13. However there are quite a few things I have going into multiple HUNDREDS of episodes. So those show up in the correct season because I have them all in season names files. But it displays them as such.
"S1 E33" while the file name is "whatever-S8-133"
It would be not a big deal but I have SO MUCH DATA on my NAS.
I have some great batch file renamers on my PC and Android. But that means I have to download TERABYTES OF DATA.
Am I just SOL?
Please send help,
Spiz

If you are mounting your media via Samba or NFS from your NAS. Then you technically don't have to download anything. There is also the SSH option if you connect to your NAS that way as well and it supports select software for renaming. Though visually is probably the best in this case for the GUI. A third option is some NAS software supports containers of programs, and you access it via your browser and then just make sure the container has access to the partition that holds the data.

All that being said the easiest and most straight forward, would likely be Samba or NFS network storage mounting. You would connect to the device and using a file explorer like you would for any file on your system, navigate to the files like you would on any system. Then use a program like Filebot and just drag and drop the files onto it and match them to the series. It then renames all the files for you for that TV Series. You still would have to go through each series one-by-one. However, much quicker and visually.

SSH method would mean you connect to your NAS through a console/terminal/tty. Then use the "cd" command to navigate to the correct directory. Since I assume the NAS is either BSD or Linux based. Your batch scripts wouldn't work, so you would have to use UNIX based shell scripts instead, but it's possible to bulk rename this way. However, you're not visually doing it, so if you mess up, well you mess up potentially in renaming everything in the location your are in.

The other method of a container. You would have to see what your NAS or NAS software on a PC supports and how it installs Docker like containers. Then figure out the in and out of mounting things.

Anyway, that's three options you could do to make life easier in the renaming and not needing to move files back and forth.
