Let your AI agent convert CUR to THM
Claude Code, Codex, Cursor and other agents can do this on your computer with Filestar. Your files stay on your machine.
Install Filestar and add it to your agents:
npm install -g filestar
filestarcli agent install
Then ask your agent:
“Convert the CUR files in my Downloads folder to THM”
Or run it yourself:
filestarcli -i file.cur -c "convert to thm"
Runs on your computer, so your files stay on it. Works on Windows, macOS and Linux. 50 free conversions with the npm install, no account needed.
Can my AI agent convert CUR to THM?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.cur -c "convert to thm" on your computer, so your files stay on it.
A CUR file is a cursor image or animation used for the Windows mouse pointer. It may be an arrow (for general use), a spinning hourglass (for waiting periods), or an I-bar (for text editing).
THM files are video thumbnail files that contain a small image or "thumbnail" of a video file. They are usually generated automatically by media players or video transcoding software and are used to provide a preview of the video.
