.fccm.json)These files contain everything needed to restore a full match mid-combat, even mid-event-resolution. They include everything from damage with staleness, through declared ranges and proxy targets, to the current event that a unit might be resolving. This data is perfect for manually switching between long running matches, moving a match to a different machine, or creating a manual ‘save point’ generally.
.txt )The simplest way to get a unit list into Command Console — Just a .txt file with the names of the units on different lines. Copying that kind of text and pasting into a match also works.
.status.csv, .status.json ).status files contain information needed for campaign record-keeping: what unit is it, its damage, ammo expenditures and munition types, crew damage and skills, etc. These files do not contain mid-match information like attack declarations, heat, or event logs.
.status files come in two forms: .status.csv for spreadsheet jockeys and .status.json for third party tools or those comfortable with json editors.
