undo replace!

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

You've overwritten the "old" file. So there's nothing left anymore to undo. It's basicly undo'ing the last copy action. Unfortunately for you the files are named the same. By undo'ing the copy you're removing the "new" file. But the "new" file was used to copy over the "old" file. Hence your "old" file is gone.

Edit: undelete programs won't help you either. You've overwritten the old files.

well, technicaly, Undelete could work seeing as the file dosn't need to have been writen to the same place as the origional.

When I want to "play" with files

I create a "Backup" directory and copy all the files I am gonna mess with into there...

Then I start to play...

Doesnt help now...but may in the future ;)

I can probably explain that, they would have used a process that used to be known as "journalling"

Say, for example you have a sales ledger and you enter transactions into it, the ledger gets updated in real time. At the same time a sort of "batch file" or "journal " of the transactions is created.

So, if the ledger becomes corrupted you just restore back to the last good save/backup and re-apply the transaction journals.

A number of office applications have the ability to create automatic back-up files, so if you lose your document or whatever, you can restore that and probably only lose your last ten minutes work:)

Now for your other point: as has already been noted, if you replace a file you have committed yourself unless the application has an inbuilt restore facility, or you have manually made a backup.

Deleting files does not actually delete them, it just makes the space available on the drive, but the data remains until it is overwritten. Thus it is possible to restore these files in many cases. The most obvious method is to use the Windows "recycle bin", where the files will not be overwritten.

Hope that helps :)

OK, say you have a file ABC.exe and you want to replace it...............create a new folder and copy the file there, then rename it ABC.old. Update your target file, and if this does not work, delete it and copy the ABC.old file back into the original location and rename it ABC.exe

ummm... thanks for ur advices nihil...

but that does not solve my question:

of course can take all the measurment to have a back up copy... but not everybody would back up

users may forget...something wrong may happen... or someone may come for help asking for this...

so, u say there is no famous way to do this... guess will find this my own ....will be posting something soon :P
