In the UK Twentieth Century Fox Home Entertainment released new "Mytharc" multi-part episodes as edited-together television movies on VHS in the mid 1990s. However, these tapes (which usually took the title of just one of the episodes comprising them but were sometimes completely re-named) were extremely expensive and released as numbered "Files" in the wrong order. For example "File 3: Abduction" ("Duane Barry"/"Ascension"/"One Beath") confusingly came after "File 1: The Unopened File" ("Anasazi"/"The Blessing Way"/"Paper Clip"). Although by the third season most mythology episodes were multi-part stories, important plot information relating to the conspiracy could still sometimes only be found in the unavailable standalone episodes to further confuse viewers of these releases. Also, "Colony"/"Endgame" and "Piper Maru"/"Apocrypha" were seemingly forgotten to be included in the series until long after many later episodes.
The truth will save you, Scully. I think it'll save both of us.
In numerous episodes in the earlier seasons, characters are seen driving cars with British Columbia License plates.

The 'previously on The X Files' segments are missing from the DVD Season boxset releases.
