Total Commander

There are more ways to restore all files view (and selection if needed) if "Only selected files" is applied:

a/ show >> all files (Ctrl+F10) or
b/ reread source window (F2 or Ctrl+R) or
c/ make TC lose focus and back or
d/ duplicate tab (Ctrl+T) before applying "Only selected", then apply "Only selected" in the duplicated tab. To return to all files view, turn to original tab (resp. close duplicated tab with only selected files if no more needed).

To restore also the selection:
- after a, b, c you can press / (slash on number keyboard)(cm_RestoreSelection),
- d - the selection is retained

In normal mode you can use: a, b, c, d
In branch view (Ctrl+B) you can use: a
In feedlist after Find files you can use: d
