Moving to recycle bin is not supported.

Error message

Moving to recycle bin is not supported.

What it means

ZipStorageFolder.DeleteAsync throws NotSupportedException("Moving to recycle bin is not supported.") under the same narrow condition as the file version: deleting the archive root (Path == containerPath) with a non-permanent option (recycle bin) and no backingFile. The recycle-bin API needs a real shell-backed file; a path-only zip root cannot be recycled. Permanent deletes and deletes with a backingFile are handled.

Solutions

1. Delete with StorageDeleteOption.PermanentDelete, or construct the ZipStorageFolder with a backingFile so the backing file's DeleteAsync is used.
2. At the call site, detect zip-root + no backing file and resolve the StorageFile first or switch to permanent delete.
3. Use the ZipStorageFolder(BaseStorageFile) constructor for archive roots that must support recycle-bin deletes.

Example fix

// before
await zipRootFolder.DeleteAsync(); // recycle bin, throws

// after
await zipRootFolder.DeleteAsync(StorageDeleteOption.PermanentDelete);

bool CanRecycle(BaseStorageFolder f) => !(f is ZipStorageFolder zsf && zsf.Path == /*containerPath*/ /*&& no backingFile*/);

static bool IsZipBacked(BaseStorageFolder f) => f is ZipStorageFolder;

try { await f.DeleteAsync(); }
catch (NotSupportedException) { await f.DeleteAsync(StorageDeleteOption.PermanentDelete); }

When it happens

Trigger: Deleting a ZipStorageFolder that is the archive container (Path == containerPath), no backingFile, with StorageDeleteOption.Default (recycle bin).

Common situations: User presses Delete (no Shift) on a .zip opened by path with no StorageFile backing, sending it to recycle bin.
