Important: When you delete a folder, it deletes the folder and any files or subfolders it contains. Consider moving or archiving the contents of the folder before deleting it. You or your administrator might be able to recover a folder and its contents from the Recycle Bin.
In SharePoint, open the document library and select the item you want to delete. (Avoid selecting the file name itself, because that would open the file.) A checkmark appears in the far left column.
Note: Does your screen look different than this and you're using SharePoint in Microsoft 365 or SharePoint Server 2019? Your administrator may have SharePoint Classic experience set on the document library. If so, see Deleting items in a SharePoint Classic experience library.
To delete multiple items, repeat this step. You can delete as many items as you want.
Select Delete on the toolbar above the list.
Select Delete in the message box to confirm your action.
The status box appears in the upper top of the document library informing you that the item has been deleted.
