# How to open .zip attachments in Adobe Reader

Adobe Reader does not allow opening .zip file attachments directly from Adobe Reader. Attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications. However, if you need this option there is a workaround to enable it by editing registry data:

1. Click Start and find Run application
2. In the Open box type "regedit" and click OK to open Registry Editor
3. In Registry Editor navigate to the following registry key:\
   HKEY\_LOCAL\_MACHINE\software\policies\adobe\AdobeAcrobat\DC\FeatureLockDown\cDefaultLaunchAttachmentPerms
4. Double-click on sBuiltInPermList
5. In the Value data field, locate the .zip file type extension
6. Change the number directly after the .zip file type extension to 1 and click OK

Reopen Adobe Reader and now you should be able to open .zip file attachments directly from Adobe Reader.
