I have a document library where users from two different groups(group_1, group_2) has access.

The document library contain various file types .docx, .xls, .pdf. What I want to do is I want group_2 user to access files with .pdf extension. I don't want group_2 users to access other file types than pdf:s.

There are several ways to achieve this. You should look for "Item Based Security". You can find a similar problem here: http://social.technet.microsoft.com/Forums/sharepoint/en-US/b0b20e7c-f5d8-4561-9d9e-9bfdf09e1d9d/how-to-give-item-level-permission-based-on-field-in-sharepoint-list
