Sometimes you do not need to replace a whole save — you need to inspect or swap a single file inside it. JKSV’s file mode lets you browse the contents of save data and backups at file level, which pairs with external save editors in a common workflow. This guide explains the workflow and the…
Knowing exactly where JKSV puts files turns a confusing SD card into a predictable system. This guide maps the three locations that matter — the program itself, your backups, and the configuration — and explains the layout inside each one so you can find, copy, and organise your saves with confidence. The three locations at…
Keeping JKSV current matters because new system versions can break older homebrew builds. Since the 11/16/2025 release, JKSV can check for and download its own updates. This guide covers both the built-in self-update and the manual method of replacing the .nro file, so you can use whichever suits your setup. The current version line The…
SVI files are one of JKSV’s less understood features. An SVI file lets JKSV import or create save data for a title that is not currently installed in the normal way.

JKSV makes it practical to move saves between two Switch consoles, or between two users, by carrying the backup files on the SD card or via a PC. This guide covers both scenarios, the importance of matching users and titles, and how to verify the moved save on the destination before you delete anything from…

This guide describes the community workflow, why sysNAND requires extra caution, and how to reduce — not eliminate — the chance of problems if you decide to proceed. Why this…
When you have dozens of games, backing them up one by one is slow and easy to forget. JKSV can back up all saves at once, either for the whole system or for a single user. This guide explains how batch backup works, how to prepare your SD card, and how to store the result…
