## Info
JKSV on Switch started as a small project/port to test some things and get familiar with libnx. A list of what it currently can do:
1. Dump and restore save data.
    * This includes the ability to dump and restore to/from any location on SD by pressing minus and using the Advanced Mode.
2. Dump system save data
    * Dumping this data is allowed, but writing back is not.
3. Open and explore bis storage partitions via the Extras menu
    * BIS Storage is opened inside a basic filebrowser. The partition's listing is on the left. Your SD is on the right.
    * Only copying to SD and file properties work on BIS partitions. Writing to and deleting are disabled for now.
4. Misc Extras:
    * Ability to remove downloaded firmware updates from NAND.
    * Terminating processes by [ID](https://switchbrew.org/wiki/Title_list#System_Modules). Allowing you to dump normally unopenable system archives.
    * Mount by System Save [ID](https://switchbrew.org/wiki/Flash_Filesystem#System_Savegames). Normally used when the terminated process makes JKSV unable to rescan titles without the Switch crashing.
	* Mount and open RomFS of process the homebrew menu takes over (if launched as NRO) (To be re-added later)
		* Hold R while opening a game or applet with Atmosphere so the homebrew menu loads. Open JKSV and press minus and select **Mount Process RomFS**. The romfs of the app should appear in the browser along with your SD on the right.

## Quick Guide
1. User Select
	* A opens the selected user's save files. 
	* Y Dumps __all__ save data from __all users__, device save data, and BCAT save data. System save data is not included in this.
	* X Changes the UI mode to a text menu based one for people that prefer 3DS JKSM style text menus instead.
	* ZR Opens the Options menu.
	* Minus opens a small menu of extras.
	
2. Title Select
	* A Opens the title for backup and restore.
	* L and R change the current user.
	* Y Dumps all saves for the currently selected user.
	* X Adds the selected title to a list of ignored titles.
	* Minus adds the selected title to a list of favorites that are pushed to the top of the title list/icons.
	* ZR __ERASES__ The selected title's save from the system. This is the same as going into settings and deleting via data management. __THIS DOES NOT DELETE JKSV's SAVE FOLDERS__.
	
3. Backup/Folder Menu
	* Minus opens file mode. File mode is a basic file browser for moving individual files and folders. This also adds the ability to restore saves from any location on your SD card.
	* Holding L or R while selecting new with A will automatically name the backup for you without opening the keyboard.
	* A creates a new backup
	* Y Restores save data from the selected folder.
	* X Deletes the selected folder.
	* ZR __ERASES__ the current save data for the title from __your system__, but leaves the archive on NAND.

4. File Mode
	* A opens directories. 
	* B goes back up a folder if possible.
	* X opens a small menu of options for files and directories:
		* Copy to [X] - Copies the currently selected item to the location opened on the other panel. Selecting the first `.` will use the directory opened as root to copy.
		* Delete deletes the currently selected item.
		* Rename renames the currently selected item.
		* Make Dir creates a folder.
		* Properties gets file size and directory size.
	* ZL or ZR Change the controlled menu.
