9.2 Files and directories

Everything JNEXT keeps for you lives under ~/.jnext.

Path	What it is
~/.jnext/jnext.conf	GUI configuration, INI format. Written by Settings > Preferences (chapter 4); also holds the debugger window layout.
~/.jnext/sdcard/cspect-next-1gb-fixed.img	The SD-card image used when --sdcard is not given.
~/.jnext/sdcard/cspect-next-1gb.img	The canonical distribution image the one above is produced from.
~/.jnext/warm-start/	The recorded NextZXOS machine a .nex load starts from (5. Running programs). One file per machine type, about 100 KB. Deleting it costs one cold boot.
~/.jnext/snapshots/	Where File ▸ Quick Save Snapshot writes and Quick Load Snapshot reads the newest .jns (5.9 Snapshots). Created on the first save. Quick Save keeps the newest 20 files it made (--quick-snapshot-keep).
~/.jnext/screenshots/	Where File ▸ Quick Screenshot writes, unless Preferences says otherwise (5.3 Display). Created on the first capture.

Beside a program you load, JNEXT also reads the debugger's files when they are there: NAME.sld or NAME.sld.txt (a source map) and, for a .nex, NAME.Memory.txt or Memory.txt (symbols). It never writes them. See Loading a source map.

Two rules worth remembering:

• Command-line options always beat saved settings. A flag on the command line wins over the same setting in jnext.conf.
• Headless runs never read the configuration file at all, so an automated run (chapter 7) cannot be perturbed by whatever you last changed in Preferences.

Documentation installed with the packages — the man page, README.md and the ChangeLog — goes to the usual system locations for your platform.
