Auto-Save
Wing auto-saves files to disk every few seconds so they can be restored if the IDE is killed from the outside or crashes. The auto-save files are placed in a subdirectory of your Cache Directory.
Wing checks this directory at startup and will offer to restore any unsaved changes. The files you select to restore will be opened into Wing as edited files.
In Wing Pro you can compare the restored files to disk using Compare Buffer with Disk item in the Difference/Merge toolbar item or Source > Difference/Merge menu area.
To keep the restored unsaved changes, save the file to disk.
To discard the unsaved changes, use Revert to Disk in the File menu.
