A Recalbox microSD card (or drive) holds several partitions. Two of them are readable by Windows:
| Partition | Format | Contents |
|---|---|---|
RECALBOX |
FAT32 | The boot partition: recalbox-boot.conf, recalbox-user-config.txt, config.txt |
SHARE |
exFAT | Your games, bios files, saves and configuration (system/recalbox.conf) |
Sometimes Windows only shows one of them — usually SHARE, the one holding the games. The card is not faulty: Windows simply failed to assign it a drive letter.
SHARE partition. On a freshly flashed card, it does not exist yet.Disk Management.RECALBOX and SHARE.Change Drive Letter and Paths….Add…, let Windows suggest a free letter, and confirm with OK.The partition appears in File Explorer straight away.


Never format a partition from this screen, and never delete a partition: you would lose either your games or the Recalbox's ability to boot.
You do not need to take your Recalbox apart to reach your files: the network share is open by default. Type \\RECALBOX in the Windows Explorer address bar — see File management.
