If PowerPoint is not properly closed for special reasons, when you restart PowerPoint, there will be an automatically recovered pptfile, which is actually located in C: /Documents and Settings/**/Local Settings/temp (hide the file first). * indicates the user name of Windows XP. The file is a temporary tmp file. there is a PPT in front of TMP, which is similar to a PPT ?. TMP format, such as ppt11.tmp.
However, if you select Delete when you exit, the TMP will also be deleted and there is no way to do so. If Automatic Recovery is ineffective, it is best to use the task manager to end the PowerPoint process, and then find the ppt11.tmp file in the Temporary Folder above, copy it to another location, and change the file name *. PPT format. Double-click it again.
To put it bluntly: the premise of generating an automatic recovery file is that you have set Automatic save in the options of PowerPoint, and the editing time exceeds the set Automatic save time, to generate a complete TMP temporary file.
