Advanced File Management : Recovering Lost, Damaged, and Deleted Files and Folders

The Recycle Bin provides protection against accidental erasure of files. In most cases, when you delete one or more files or folders, the deleted items go to the Recycle Bin, not into the ether. If you change your mind, you can go to the bin and recover the thrown-out items. Eventually, when the bin fills up, Windows begins emptying it, permanently deleting the files that have been there the longest.

The following kinds of deletions do not go to the Recycle Bin:

• Files stored on removable disks

• Files stored on network drives, even when that volume is on a computer that has its own Recycle Bin

• Files deleted from a command prompt

• Files deleted from compressed (zipped) folders

You can bypass the Recycle Bin yourself, permanently deleting an item, by holding down the Shift key while you press the Delete key. You might want to do this if you need to get rid of some very large files and you're sure you'll never want those files back. Skipping the Recycle Bin in this case will reclaim some disk space.

You can also turn off the Recycle Bin's services permanently, as we explain in the following section.

2. Changing Recycle Bin Settings

To see and adjust the amount of space currently used by the Recycle Bin for each drive that it protects, right-click the Recycle Bin icon on your desktop and choose Properties from the shortcut menu. In the Recycle Bin Properties dialog box (shown in Figure 1), you can select a drive and enter a different value in the Custom Size box. Windows ordinarily allocates up to 10 percent of a disk's space for recycling. (When the bin is full, the oldest items give way to the newest.) If you think that amount of space is excessive, enter a lower value.

Note:

If you don't see a Recycle Bin icon on your desktop, it's probably hidden. To make it visible, right-click the desktop, choose Personalize, and then click Change Desktop Icons. In the Desktop Icon Settings dialog box, select Recycle Bin and click OK. If you use the Show All Folders option in Windows Explorer.

If you'd rather do without the Recycle Bin for a particular drive, select the drive from the Recycle Bin Properties dialog box and then click Do Not Move Files To The Recycle Bin. Remove Files Immediately When Deleted. This action is equivalent to setting the maximum capacity to 0.

Whether the Recycle Bin is enabled or disabled, Windows normally displays a confirmation prompt when you delete something. If that prompt annoys you, clear the Display Delete Confirmation Dialog check box.

3. Restoring Files and Folders

When you open the Recycle Bin, Windows displays the names of recently deleted items in an ordinary Windows Explorer window. In Details view (see Figure 2), you can see when each item was deleted and which folder it was deleted from. You can use the column headings to sort the folder—for example, to display the items that have been deleted most recently at the top, with earlier deletions below. Alternatively, you can organize the bin by disk and folder by clicking the Original Location heading. If these methods don't help you find what you're hoping to restore, use the search box.

Note that deleted folders are shown only as folders; you don't see the names of items contained within the folders. If you restore a deleted folder, however, Windows re-creates the folder and its contents.

The Restore This Item command (on the toolbar) puts the item back in the folder from which it was deleted. If that folder doesn't currently exist, Windows asks your permission to re-create it. If no object is selected, a Restore All Items option is available on the toolbar. If your Recycle Bin contains hundreds or thousands of deleted files dating back weeks or months, this option can create chaos. It's most useful if you recently emptied the Recycle Bin and all of its current contents are visible.

If you want, you can restore a file or folder to a different location. Select the item, choose Edit, Move To Folder, and then specify the new location. (If the menu bar isn't currently visible, you can right-click the item, choose Cut, and then paste it in the new location.) Or, simplest of all, you can drag the item out of the Recycle Bin and put it where you want it.

4. Purging the Recycle Bin

A deleted file sitting in your Recycle Bin takes up as much space as it did before it was deleted. If you're deleting files to free up space for new programs and documents, transferring them to the Recycle Bin won't help. You need to remove them permanently. The safest way to do this is to move the items to another storage medium—a different hard disk or a removable disk, for example.

If you're sure you'll never need a particular file again, however, you can delete it in the normal way, and then purge it from the Recycle Bin. Display the Recycle Bin, select the item, and then press Delete.

To empty the Recycle Bin entirely, right-click the Recycle Bin icon on your desktop and choose Empty Recycle Bin from the shortcut menu. Or display the Recycle Bin and click Empty The Recycle Bin on the toolbar.

5. Restoring Previous Versions of Files and Folders

Need a time machine? With Previous Versions, you have it. This invaluable feature is a side benefit of the way the operating system now creates backup copies and restore points. With System Protection turned on (its default state), Windows creates a daily restore point that lets you roll your system back to an earlier state in the event that a new installation or some other event creates instability.  Restore points are built from shadow copies, which are essentially change logs for files and folders. Shadow copies are also created by the Windows Backup program. If you perform regular periodic backups, you have the Backup program's shadow copies as well as those created by System Protection.

You can't open or manipulate shadow copies directly. However, you can access their contents indirectly via the Previous Versions tab of the properties dialog box for any file, folder, or drive icon, or you can use the Restore Previous Versions command on the File menu in Windows Explorer. Using Previous Versions, you can open, copy, or restore a document or folder as it existed at an earlier point in time. This feature is a lifesaver if you accidentally delete files from a folder or want to "roll back" to an earlier version of a document you've been working on for days or weeks; if you have a shadow copy from a time before you made the deletions or changes, you can recover the earlier version by restoring individual files or replacing the folder's contents with the earlier version. (As an alternative to restoring the earlier version, you can create a copy of the earlier version of the file or folder and then compare its contents to the current version.)

The Previous Versions feature is independent of the Recycle Bin. Purging the Recycle Bin (or declining to use it) has no bearing on the availability of shadow copies.

To see what previous versions are available for a file or folder, right-click the item in Windows Explorer and choose Restore Previous Versions. The Previous Versions tab of the object's properties dialog box (see Figure 3) will list the available shadow copies. Select the one you want, and then click Open (to view the file or folder), Copy (to create a copy of it without changing the original), or Restore (to overwrite the object in its current state with the selected copy).

Note:

Previous versions are not available for system files or files in an offline cache. You can use the feature to restore earlier versions of uncached files on network shares, however. For more about offline caches, see the following section.
