Open TMP files in your browser
A .tmp is a file an app made for itself while it worked, and sometimes the only copy of your work. See what yours holds right here. Nothing leaves your device.
Or drop it anywhere on this page
What you'll see
Your file opens as what its bytes say it is, a drawing, a document, a database or a text, or on its About card when only its own app reads it.
- Told by its bytes • Whatever its name
- Word, Excel and PowerPoint inside • In their own viewers
- Drawings and databases • Opened as what they are
- Every byte in the hex editor • Search, Go to and Inspect
About TMP
Apps write .tmp files while they work and delete them when they close, so the ones left behind are from an app that crashed or a computer that was switched off: Word’s ~WRL0001.tmp copies of a document it was saving, Excel’s numbered workbooks, an installer’s unpacked parts and downloads in progress.
Filepeek reads its bytes, so a Word, Excel or PowerPoint file kept as .tmp opens in its viewer, a picture as the picture, a ZIP as a folder, a database lists its tables and a text opens as text. One that’s only the start of a file opens as far as it got.
Many .tmp files hold an app’s own data that only it reads, and those open on their About card: what kind of file its bytes say it is, the text and the files inside it, and every byte in the hex editor.

Questions
How do I open a .tmp file?
Drop it here. It opens as what its bytes say it is, or on its About card when only the app that made it reads it.
Can I get an unsaved Word document back from a .tmp?
Often. Word’s ~WRL and ~WRD .tmp files are copies of documents it was saving, and they open here as Word documents. Look in the document’s own folder, with hidden files shown, and in %temp%.
Where are .tmp files kept?
Most are in your user’s temp folder, which %temp% in File Explorer’s address bar opens. Office keeps its own beside the document they belong to, hidden.
Is it safe to delete .tmp files?
Yes, once the app that made them is closed. Disk Cleanup and Storage Sense in Windows delete old ones for you.
Why won’t my .tmp open?
Most hold an app’s own data in a layout only it reads. Its About card says what it can of it, and the hex editor shows its bytes.
