This procedure requires WinZip to proceed.
With 'Make Back-up on Save enabled, w'hen saving a file a second time, CorelDRAW will rename the original file to "Backup of filename.cdr". If you were to re-save the file again, because Windows will not allow two files with the same name, in the same location at the same time, CorelDRAW will save the file as a .tmp file. Once the save process is complete, the "Backup offilename.cdr" is deleted and the .tmp file is renamed to "Backup of filename.cdr". With this in mind, it may be possible to rename the .tmp file to .zip and then extract the data, or you can try to use repair corel draw file
