Yes — you can absolutely use app.use(...) instead of app.all(...) for WebDAV methods like COPY. They are functionally equivalent if you're doing manual req.method checks inside.
These are equivalent:
// Using app.all
app.all('/*', (req, res, next) => {
    if (req.method !== 'COPY') return next()
    // handle COPY...
})
// Or Using app.use
app.use((req, res, next) => {
    if (req.method !== 'COPY') return next()
    // handle COPY...
})

Express only provides route methods for the standard HTTP methods defined in the HTTP/1.1 spec:
Built-in Express method	Purpose
app.get()       Retrieve data
app.post()      Submit data
app.put()       Replace data
app.delete()    Delete data
app.patch()	    Partial update
app.options()	Preflight
app.head()	    Headers only
app.all()	    Any of the above
What about WebDAV methods like PROPFIND, MKCOL, MOVE, COPY, etc.?
These are not natively supported as top-level methods in Express.
To handle them, you have to use app.use(...) or app.all(...)

Middleware: Think of it like a filter or pipeline
Each request flows through the middleware stack. Each function can:
- read from the request (req)
- modify the response (res)
- terminate the request (by sending a response directly)
- or pass control to the next middleware with next()

cat cpanel-server-2.js | grep ^app
    app.use((req, res, next) => {
    app.options('/*', (req, res) => {
    app.use((req, res, next) => {
    app.use(express.raw({ type: '*/*' }))
    app.get('/*', (req, res) => {
    app.put('/*', (req, res) => {
    app.delete('/*', (req, res) => {
    app.use((req, res, next) => {
    app.all('/*', (req, res, next) => {
    app.all('/*', (req, res, next) => {
    app.all('/*', (req, res, next) => {
    app.use((req, res) => {
    app.listen(port, () => {


    const url = new URL(req.url)
    const path = url.pathname
    ->
    const path = new URL(req.url).pathname
