Tar and Feather

/tär ən(d) fe-t͟hər/

[from UNIX 'tar(1)']

vt. To create a transportable archive from a group of files by first sticking them together with 'tar(1)' (the Tape ARchiver) and then compressing the result (see compress). The latter action is dubbed 'feathering' by analogy to what you do with an airplane propeller to decrease wind resistance, or with an oar to reduce water resistance; smaller files, after all, slip through comm links more easily.
