iCloud trying to upload deleted files

I stuck with a problem that constantly drains my mac battery and overloading it. I accidentally copied and unarchived my work files, and the problem is there's about billion (don't know for sure, really big amount) of small files with total size of 12 GB. I deleted it and disabled iCloud syncing, but no luck -- bird service and cloudd (iCloud daemon I guess) wont stop working and trying to upload this huge amount of files, which is really really slow (not because of my internet connection but because of their amount). The stop button doesn't work, and I have no idea how can I stop this, because it's loading ~200% of CPU in total (2 cores each per service).
