An update forced me to change folder structure now I have to manually change the naming of all files

I've been developing my game for several years at this point, and when I first started I selected the flat folder structure without any knowledge if it's better or worse than the folder one. I've been getting reminders that the flat folder structure is deprecated for a year or longer, but I didn't think they would straight up force me to change to folders in another update. I've already done a lot of work on the project file, so I can't rollback to the previous version. Is there any way to go back to the flat structure, or I'm SOL and need to spend several hours manually rewriting all paths to my files?

For example, my files used to look like that

And now I have to make everything look like this

All it takes is a few clicks, and you won't need to change anything in the events.

Move all the sound files to the root of the “Sound” folder.

Move all the sound files to the root of the “Sound” folder.

I have around 5000 voice lines. The engine implodes from moving 10% the amount of files

How is that for a solution, guys? Am I already a senior Construct 3 developer or maybe someone even greater?
