Hello, i check and see the folder is the right, looks like i lose a folder, long time ago that i start Obyte 4.x...
This is your program folder. It's small, you don't need to bother about moving it to another partition.
Which datas i can deleted, to synch the wallet new?
The data folder.
However, I'm not sure what would be your next step after re-syncing. If you restore from backup, all data will be overwritten.
