A barrister accused of covertly filming up women's skirts in supermarkets in Sussex also kept images on his home computer, Canterbury Crown Court heard.
Jurors heard the computer contained an "evidence eliminator" programme made to wipe files off a hard-drive.
Simon Austin Hamilton, 35, of Haringey, north London, denies five charges of outraging public decency in 2001.
He also denies eight charges relating to making, owning and taking indecent pictures of children from 2001 to 2003.
Mr Hamilton faces six charges of making indecent photographs of a child.
He also faces two charges of possessing an indecent photograph of a child for show.
And he faces two charges of taking indecent photographs of a child.
On Friday, the court heard Mr Hamilton had a catalogue of files on his home computer, one of which was called "upskirts".
That file did not contain any of the five reels of film Hamilton had taken at supermarkets in Chichester, West Sussex, the court was told.
Jurors heard Mr Hamilton took shots of girls on trains using a mobile phone which were stored in a computer file called "my own work".
And one series of images called "Baby Jane" showed a girl aged between three and five involved in sex acts.
Prosecuting, James Townend QC said Mr Hamilton's user name was "Mad Hatters" which referred to the football club he supported, Luton Town.
At the time of the offences, Mr Hamilton lived in Bosham, West Sussex, with his fiancée. The couple later married.
The trial continues.
