During editing, WingEditor keeps saving users' editing to some temporary files. If system crashes during editing, users can recover their editing from corrsponding temporary file.
Go to the directory where the source file is located, and files name with the original file name and end with \.tmp.\ plus a sequence of digits should be the corrsponding file. Check the file's time mark, users will be able to find the right one.
As a simple example, the following name appears to be a temporary file for javaeditor.java,
javaeditor.java.tmp.854341732,
