“PowerPoint can’t open this type of file path/filename.” tends to prompt while trying to open a PowerPoint file then most probably your Microsoft Office is not recognizing it. This problem may be a file-format issue, or it may be a file-corruption issue that requires repair.

Error Message

The selected file does not appear to be a valid Microsoft PowerPoint file. It might be a file created by a different program.
Try double-clicking the file in Windows Explorer to see if another program will open it. If PowerPoint opens again when you double-click the file in Windows Explorer, it is possible that the file is not a PowerPoint file but that its extension was renamed to be that of a registered PowerPoint file type (such as .ppt, .pptx, .pps, .ppsx, .pptx, .pot, or .potx) but the file is not a PowerPoint file.
To determine which program can open the file, try any of the following:

  • Contact the original author (if known) to find out which program was used to create this file. Then rename the file with the correct extension so that it can be opened by that program.
  • Try opening the file in other programs.
  • If you, or someone you know, are very knowledgeable about the software, examine the file header in a text editor to determine which program can read the file.

Another possibility for error message “Powerpoint can’t open this type of file” is that the file was damaged during the transfer from another computer. Try transferring the file again. The file might have become corrupted. If you have a backup copy of the file, use it.
