Cueball is shown literally digging through a pile of old files; which is a metaphor for looking through old files on his computer. The layers of the pile are arranged much like geological rock formations where older strata are deeper down than younger layers. The files are in concentric layers because each directory is embedded in the previous directory. Therefore, the "Documents" folder contains an "Old Desktop" folder, which contains a folder with files recovered from an older system, which itself contains a "My Documents" folder, which contains a folder with files copied from a Zip Disk from high school. The result is that files from high school have survived in his present-day machine. These older folders serve as a time capsule of sorts, storing old files from AOL, NYET, and Kazaa. These files are meant to be analogous to the fossils and artifacts found in lower, older rock layers. The sizes of the files decrease as Cueball goes deeper, since data storage has gotten cheaper over time. When the Zip Drive first came out, it cost $200 USD (plus $20 per 100 MB floppy). As of 2019, $200 could buy you at least an 8 TB portable external hard drive. In the 1990s, during AOL's heyday, 10+ GB hard drives were prohibitively expensive and a terabyte of data was unimaginable to most users. Deep down, Cueball discovers several files he is surprised about, including a poetry file which embarrasses him as he does not remember writing poetry.
