run out of inodes by using chest

Hi,

I tried chest on a large file and on an ubuntu 16.04 system. Chest created millions of files on my hard disk and I was running out of inodes. I have plenty of hard disk avaiable but I can not use it because inodes usage is at the peak. What can I do about it? Can I reduce the millions of generated files to hundereds? Is there any option for this?

Thanks in advance
