Empty the recycle bin or restore your files
Running out of storage space or want to recover a deleted file from a SharePoint library? Check the recycle bin. When you delete an item from team site library, or from a list, it isn’t completely removed from SharePoint. Deleted items go into the recycle bin, where they stay until they’re automatically removed 93 days later. Meanwhile, you can remove files from the recycle bin to free up storage space or restore items to their original location if you’ve accidentally deleted them.
To open your recycle bin
On a SharePoint site left navigation, choose Recycle bin.
The Recycle Bin opens.
To delete or restore items from your Recycle Bins
In the Recycle Bin page choose Delete Selection to delete or Restore Selection to recover the selected files.
When an item is restored, it is restored to the same location that it was deleted from.
