ext2 filesystem, altough not implemented completely, but simulated (with some functions used as an abstraction of lower-level stuff)

parts not inside ext2fs.c were provided by the lecturer!, also some CSAPP libraries were used

implements data structures from first revision of ext2, so that syscalls like mount(), open(), read(), readlink(), getdirentries(), stat(), etc. work

make -> for building whole project
make clean -> to clean directory from executable and object files
make format -> to format all .c files
make test -> to run test provided by the lecturer (sometimes may fail)
