Press Win + R, then copy and paste %APPDATA% into the window that pops up. Once the folder opens, look for the Renpy folder, and inside it, find all the folders I mentioned above and delete them. That’ll save you +-40 megabytes.
If you were thinking of just using Windows Search to track them down, I hate to break it to you, but File Explorer might not even show those folders, since AppData is hidden by default
P.S.
If you're talking about the actual game files (the ones you launch), you should search for them under the names TSITU or EOFA_ENG. You could also try Edges of Adulthood (in theory, at least, though I don't recall ever actually naming it that).
In this case, the standard Windows search will do the trick just fine
