FTB money file uploads

hi aternos team, i am here because i want to upload a file with all my custom quest for ftbmoney mod, but i can't. please let all users upload their folders with files (.nbt) that make the shops, thanks. Hope you understand that it is much more easier doing shops in singleplayer than in a server, and that's why im asking this.

this isthe link to the files on aternos where i want to upload my file.

custom modded server

no sorry
but i know it just needs 1 nbt file to be uploaded for the whole mod

the mod doesn't have any information anywhere, there is no wiki for it.

when i want to upload it it says file extension is invalid (and yes i have tried to upload i in rar)

I found out about it when i was making my own modpack and messing with the configs.when i deleted it all of the shops data was gone. (its like the player inventory in minecraft every player's inventory has its own uniqe .nbt)
