There is one of the well-known zip bombs called 42.zip. This zip file consists of 42 kilobytes of compressed data and five layers of attached zip files in sets of 16. Each lower-level archive contains a 4.3-gigabyte file that contains 4.5 petabytes of uncompressed data. 1 petabyte is 1000 terabyte - much more storage space than an average computer system has. Flooding it with 4500 terabytes of data means immobilyzing it.
