When Aseprite is running, it saves some temporary data to restore your
sprite in case that your computer (or Aseprite itself) crashes.
This temporary data is saved in a subfolder named
sessions inside your
sessions might be several subfolders:
The name of these folders (e.g.
20180405-165510-1128) has a meaning,
DD: Date (year, month, day) when the session started (when Aseprite was launched).
SS: Time (hour, minute, second) of that day when the session started.
PID: Process number/identifier of the Aseprite instance that was handling that session folder.
Each of these folders contain useful data to restore some sprites that you might have lost in the crash. When you start Aseprite again, you may see this button to recover those sprites:
If you don't see the "Recover Lost Sprites" button when you launch
Aseprite, but you have one of these
folder in your Preferences Folder, you can
compress one of those folder in a
.zip and send it to
email@example.com. We can
try to recover your data.
