So my simple question is:

using windowz...

after replacing a file, is there any progs, any way, any trick to undo the replace...

at home, i tried few things:
created text documents, same name, different location, then replaced one another using copy, did an undo copy what happens is that the new pasted dissapears, but the old one does not come again

that is all i tried.... any tips or trick
i think this might be useful for anyone for the future

i know there must me something... there is a way to recover deleted files... ever to recover after format...

10x in advance for replying
