An inode is a data structure used to keep information about a file on your hosting account. Hard drives partitions are made up of two pieces: the actual data blocks (ie: 100GB) and innodes (that store the information about the data). There is so many available innodes on a hard drive partition that it isn’t something that is typically talked about in terms of hard drive or computer capacity. Unlike some other web hosts we don’t use tricks like inodes to limit your account.
