Exactly this is still happening for me, i.e. when running on iOS only, using
`FileEntry.copyTo()` onto an existing file results in a `PATH_EXISTS_ERR`.
Looking into the source code at
`plugins/cordova-plugin-file/src/iOS/CDVLocalFilesystem.m`, in the
`copyFileToURL()` routine, lines 493-495 are:
```
} else if (bNewExists) {
// the full destination should NOT already exist if a copy
errCode = PATH_EXISTS_ERR;
```
As @coulson84 notes above, the (now deprecated) standard at W3C says that
copyTo() should delete an existing destination file before copying. Should
this be followed in the source code above? Or perhaps the plugin's `copyTo()`
routine should have an `options` argument that allows this?
It's not hard to work around-- on iOS, the app can just delete a destination
file before copying-- but perhaps this could be fixed for the sake of
consistency with other platforms, or at a minimum documented under "iOS Quirks".
