Install Filestar and add it to your agents:
npm install -g filestar
filestarcli agent install
Then ask your agent:
“Convert the JAR files in my Downloads folder to LHA”
Or run it yourself:
filestarcli -i file.jar -c "convert to lha"

Can my AI agent convert JAR to LHA?

A JAR file is a Java archive (JAR) file used by the Java Runtime Environment (JRE), a framework used for executing Java programs. JAR files may serve as program libraries or as standalone programs that run if the JRE is installed on the computer or mobile device.
The LHA (also known as LHARC) file type is a compressed archive format developed by Haruyasu Yoshizaki. It primarily uses the LZSS algorithm and Huffman coding for compression, enabling the efficient packaging of multiple files and directories into a single, smaller file. Initially designed for use in the DOS operating system, LHA became popular in Japan and was widely adopted for software distribution on platforms such as Amiga and early versions of Windows.
