Select at least one file (folders are skipped)
My Files shows library.errors.selectFileSkipFolders when the selection has no files (folders only, or empty after skipping folders).
Why this happens
Some bulk actions apply to files only. Folder move is separate (Moving folders is not supported yet. Deselect folders to move files only).
Diagnose and fix
1. Select at least one file (folders in the selection are ignored for this action).
2. Retry the bulk action.
3. See My Files library (browse, search, sort).
4. See Move failed if a move still fails afterward.
