I am new to electron and this forum, I want to move a file to a certain location on a computer with a drag and drop of a file in an electron program using child_process. the file must be moved on the click of a button, here is my code:

  document.addEventListener('dragover', (e) => {
    e.preventDefault();
    e.stopPropagation();
});

document.addEventListener('drop', (event) => {
    event.preventDefault();
    event.stopPropagation();

    let pathArr = [];
    for (const f of event.dataTransfer.files) {
        // Using the path attribute to get absolute file path
        console.log('File Path of dragged files: ', f.path)
        pathArr.push(f.path); // assemble array for main.js
        const apply = document.getElementById('apply')
apply.addEventListener('click', () => {
applyTheme()
});
        async function applyTheme() {
          const { stdout, stderr } = await exec('mv ', f.path, ' %userprofile%\\.spicetify\\Themes');
        
          if (stderr) {
            console.error(`error: ${stderr}`);
          }
          console.log(`${stdout}`);
          
        };
    }
    console.log(pathArr);
    
});

but I get this error:

Uncaught (in promise) TypeError: The argument 'args' is invalid. Received ' %userprofile%\\.spicetify\\Themes'
