'''SHSCRAP.DLL''' is part of the [[Object Linking and Embedding|Object Linking and Embedding (OLE)]] mechanism. It implements support for [[Shell Scrap Object File|shell scrap file]]s, which are automatically created when you drag selected content from an OLE-capable application into an Explorer window or desktop,<ref>{{cite web |url=https://support.microsoft.com/en-us/kb/138275/|title=WD: What is a Scrap (.shs) file? |work=Microsoft Knowledge Base}}</ref> but you can also use the [[Object Packager]] to create them. They can then be dragged into another OLE-capable application.

This functionality was removed from Windows Vista (and therefore later versions) to improve security and rid the operating system of generally unused functionality.<ref name="scrap_the_scraps">{{cite web|url=https://technet.microsoft.com/en-us/magazine/2008.02.windowsconfidential.aspx|title=Windows Confidential: Scrapping the Scraps |author=Raymond Chen |access-date=2011-12-14}}</ref> Scrap (.shs) files have been used by viruses because they can contain a wide variety of files (including executable code), and the file extension is not shown even when "Hide file extensions from known file types" is disabled.<ref>{{cite web |url=https://www.symantec.com/security_response/writeup.jsp?docid=2000-121915-4852-99 |archive-url=https://web.archive.org/web/20061110163040/http://www.symantec.com/security_response/writeup.jsp?docid=2000-121915-4852-99 |url-status=dead |archive-date=November 10, 2006 |title=VBS.Stages.A |website=symantec.com[[Broadcom#Symantec enterprise security|Symantec]]}}</ref> The functionality can be restored by copying registry entries and the [[Dynamic-link library|DLL]] from a [[Windows XP]] system.<ref name="scrap_restore_hack">{{cite web|url=https://answers.microsoft.com/en-us/office/forum/office_2010-word/how-to-open-shs-files/c4618ebd-e248-4340-ab6a-1b79fd808c46|title=How to open SHS files|access-date=2011-12-14}}</ref>
