Thanks for sharing the details! Try to identify what type of file it really is (Most Important Step)
Many .TMP files are actually hidden versions of other file types (PDF, DOCX, ZIP, JPEG, etc.). You can often open them by revealing their actual file type:
Try this:
- Right-click the .TMP file → Rename
- Add common file extensions one at a time and try opening them:
Try these:
-
.pdf -
.zip -
.jpg -
.png -
.txt -
.docx(even without Office — LibreOffice can open it)
Example:
If the file is named:
report.tmp
Rename it to:
report.pdf
Try to open it. If it fails, rename it again and try .zip or .jpg.
This works surprisingly often because apps create temp files using .tmp even though the content is another file format.
See if this helps. If you need further assistance just let me know.
