SharePoint
has built-in Recycle Bin functionality that enables you to retract
deletions. By default, files and items that were deleted are kept in
this Recycle Bin for 30 days, but the site you are using might have
different settings. After this time, they are moved to the site
administrator’s Recycle Bin. So if you don’t see a file or list item
that you have deleted in the past, ask your administrator to recover it
for you.
To
restore a file, click the Recycle Bin link in the left navigation bar.
Clicking this link opens the Recycle Bin page, which shows all the
files and list items you have deleted in that specific site (see Figure 1).
In the deleted items list, you
can see the name of the deleted item or file, the original location
(site and document library or list and folder), and other data about
the file or item, such as who created it in the first place, when it
was deleted, and, for files, what size it was.
To restore one or more
files and items, select the check box next to each item you want to
restore and click Restore Selection. The item or file is restored with
all its versions and properties.
You can also permanently delete an item or file from the Recycle Bin by selecting Delete Selection.
