What is a .OTH file?
Everything worth knowing about Microsoft PowerToys Explorer tool files.
An .OTH file is an OpenDocument HTML Template developed by OASIS. This type of web document contains formatting and structure used to generate HTML pages. These files are typically opened using office suites such as OpenOffice.org and NeoOffice.

Is my .OTH file uploaded anywhere?
No. Your .OTH file is read and converted for you. The first time, a small open-source conversion component is downloaded and then cached.
Why does my older .OTH file look plain?
Some older word-processor files keep their formatting in a complex binary layout. The viewer shows all the text and tables reliably; richer formatting for those files is coming with server-side conversion.
Are macros in a .OTH file safe here?
Yes. The viewer never runs macros. It only reads the document text, styles and images, and tells you when a file contains macros.
Can I edit my .OTH file?
This is a viewer. You can copy the text or save it as HTML/TXT and edit it elsewhere. An online editor is on our roadmap.
It says my .OTH file is something else. Why?
We check the file's signature, not just its name. If a file was renamed, the viewer tells you what it really is and which tool opens it.
