Which data files should I wipe?

Hi,
I have some questions :
For example when i wipe My server i want to keep from data folder “kits”. There are 2 Files with kits. One with kits from Game And another one with kits logs. I am not a Developer to understand wich one i have to delete. For example sometimes i forgot to delete NteleportationHome, nteleportationTPR And much More, My question : if this Files are More And More bigger server run slower? And in data folder are a lot of Files from almost all plugins, i want to delete logs from this Files , are too big

 

I will answer the kit one the rest you need to ask in the plugin topic delete the kits_data.json only from data folder and only when server is offline and only do this the full wipe on the first week of each month

 

So i have to ask Every Developer one by one ? I have almost 100 plugins . And kits_data slow My server ? I have modded server xMilion So i Did Full wipe everyweek

 

You only posted two above and the best way would be talk to someone over Skype or discord would be faster
