Yes, you can recover files who were breastbone or previously modified (eg if you have made changes in a .doc file and want to see what it looks like before it is saved.) And if you use Windows Vista.
Windows Vista allows you to restore deleted files or the previous versions of some files and folders, with the help of restoration points created by the tool System Restore. In order to be able to use this method you must create the data/rescue points before (Restore Point). Specifically, the system is set as a particular time record on hard disk The state of the files and folders from the hour at which this point is created, so that you can access the files as they looked at the time when "Restore Point" was created.
Activation System Restore on Windows Vista.
First of all, you need to make sure you have a free hard 300 MB, that System Restore can run normal. In many cases System Restore requires up to 15% from the total hard disk space. Also remember that System Restore will not work On the partitions in format Fat32.
To check if you are activated System Restore, you must follow some simple steps.
1. Click on the Start Bar
2. Right click on "Computer"And in the menu that opens click on"Properties"(See the image below.)

3. In the window to open you, somewhere on the left side of the left.System protection”. Click.
4. The partitions for which "System Restore" is activated have the cottage of their right. For example, in the image below it is activated for system partition: Vista (C :) (System).

OK. It is not sufficient to activate this function, if no restoration is created or if not set as a certain date/hour CR
automatically such a point (Restore Point). If this option is activated, Windows Vista will create a Restore Point every day, and every time changes in the system appear. (installing a new program or Windows updates, for example).
To create a restoration point, click on the button ”Create"(See the image above) and give a name to this point, I know that you do not confuse it with another. It is very simple.
To recover deleted files and folders using System Restore, you must follow a few steps.
1. Right click on a file or folder from those that have been saved.
2. From the window that will open, select the folder you want to recover.
3. Click on the button ”Restore"From the tab"Previous Versions”.
4. Pull the folder (dear & Drop) in the location where you want to save it.

5. The deleted/modified folder is recovered :)

This method is especially useful to those using Windows Vista Ultimate, Business or Enterprise. Last days I understood what it means not to have a healthy backup at the system. I wiped out some data by mistake and I had no Restore Point/Backup.
For Windows Vista Home Edition I chose a safer solution (I say) to protect the files. Protect your files by backing them up. A method that in relation to the space occupied on the hard disk requires some resources and time. Compared to the above method, it does not use "shadow copies”.
Come back;).
