Folder

Folder (フォルダ), also known as Chip Folder (チップフォルダ), is a feature from the Mega Man Battle Network and Mega Man Star Force series. A Folder is used to store 30 Battle Chips or Battle Cards that will appear in the Custom Screen.

There is a limit of how many copies of the same chip can be added in the folder. In the first Mega Man Battle Network game, the limit is 10 copies, reducing to 5 in Mega Man Battle Network 2, 4 in Mega Man Battle Network 3 to 5, and 3 in Rockman.EXE 4.5 Real Operation and the Mega Man Star Force series. In Mega Man Battle Network 6, they are restricted according to their size: 5 copies of chips with size of 19 MB or lower, 4 copies for 20-29 MB, 3 for 30-39 MB, 2 for 40-49 MB, and 1 for 50 MB and higher.

In the first two Mega Man Battle Network games, the Folder can only contain 5 Navi Chips. In the third game onward and the Mega Man Star Force series, this changed with the addition of classes, the limit being 5 Mega Class Chips and 1 Giga Class Chip. The limitation can be increased with some Navi Customizer programs. Except for the first game, the Folder can't hold duplicates of Navi, Mega, and Giga Chips.

Starting by Mega Man Battle Network 3, the user can select a specific Battle Chip to appear in the beginning of the NetBattle, but only if its memory doesn't exceed the Folder's limit. In the beginning the regular memory is 4 MB, and it can be increased with upgrades.

In Mega Man Network Transmission, the Folder must contain 20 Battle Chip and the initial regular memory is 8 MB.

The Folder works in a different way in Mega Man Battle Chip Challenge.

The game has seven Extra Folders, the four N1-Folders and the Hades Folder are available in Hades Island, XtraFldr in ACDC Square, and Famous Folder in the Beach Street TV Station Lobby.
