Inodes and Disk Space

I’m confused, it seems that you do not really offer unlimited Space
because you limit our files or directories.

Inodes - is a data structure on a filesystem on Linux and other Unix-like operating systems that stores all the information about a file except its name and its actual data. A data structure is a way of storing data so that it can be used efficiently
Disk Space - is the amount of storage you have for your website’s files. These files include any programs/systems (like WordPress), images, documents, video, etc. How much Disc space you have is based on how much you have purchased with your hosting account.

I understand it because I know you are just a reseller from internet or byrthost.
