Local paths
Melvor Idle 2 save file location
The developer lists three local data directories for the cloud login cache jwt.dat. The cited post does not identify the actual character-save files or confirm their layout. For a documented portable save backup, use the clipboard export described in the official FAQ and Early Access announcement.
Documented data directories, not a confirmed save-file map
Windows: %APPDATA%\Games By Malcs\Melvor Idle 2\data. macOS: ~/Library/Application Support/Games By Malcs/Melvor Idle 2/data. Linux: ~/.local/share/Games By Malcs/Melvor Idle 2/data. These paths and their capitalisation come from the Cloud Login Issues section of the pinned Known Issues post, a single official source.
jwt.dat in that same data folder is the cloud login cache, according to the same post. Deleting it is a troubleshooting step they describe for cloud login problems, not a routine backup step. Read the post before you delete anything.
A cache stores login state, not a documented portable copy of a character. The post does not provide the save-file names. Copying jwt.dat, or assuming this directory contains every required save component, is not a backup procedure established by that source.
A backup that does not involve the folder
The pinned FAQ and 29 October Early Access announcement describe an export from the character-select gear menu: choose Copy save string to clipboard, paste the result into a text file, and keep it as a backup. The FAQ also describes Melvor Cloud backup when logged in and Steam Cloud backup. Demo transfer to Early Access is automatic; this extra copy is optional, not a migration requirement.
| OS / item | Documented path or limit |
|---|---|
| Windows | %APPDATA%\Games By Malcs\Melvor Idle 2\data |
| macOS | ~/Library/Application Support/Games By Malcs/Melvor Idle 2/data |
| Linux | ~/.local/share/Games By Malcs/Melvor Idle 2/data |
| Cloud cache | jwt.dat inside the data folder |
| Actual character-save filenames | Not identified in the cited post |
Editorial notes
The three paths are quoted from one developer troubleshooting post about jwt.dat. That post does not identify the actual character-save files. Clipboard export is documented separately in the developer FAQ and Early Access announcement; no private client session is cited.
Questions
Where is the Melvor Idle 2 data directory on Windows?
The developer gives %APPDATA%\Games By Malcs\Melvor Idle 2\data for jwt.dat cloud-login troubleshooting. The post does not identify the actual save-file names.
Is jwt.dat my save backup?
No. The cited post identifies it as a cloud-login cache. Use the documented clipboard export for a portable character backup; cloud backup is a separate feature.
Should I use a save editor?
No editor is recommended here. Use the official clipboard string if you want a portable backup.
