Adobe Premiere Elements uses conformed audio files and preview files to optimize performance, allowing real-time editing, high processing quality, and efficient output. All scratch disk files are preserved across work sessions. If you delete preview files or conformed audio files, Adobe Premiere Elements automatically recreates them.</p><p class="paragraph">By default, scratch files are stored where you save the project. The scratch disk space required increases as your movie become longer or more complex. If your system has access to multiple disks, you can use the Edit > Preferences > Scratch Disks command to specify which disks Adobe Premiere Elements uses for these files. For best results, set up your scratch disks before you begin a project.</p></ol><p class="seealso">Related Subtopics:</p><ol><div class="seealsolink"><a href="1_4_10_1.html">Types of scratch disks</a></div><div class="seealsolink"><a href="1_4_10_2.html">Guidelines for maximizing scratch disk performance</a></div><div class="seealsolink"><a href="1_4_10_3.html">Setting up scratch disks</a></div></ol><hr /><div class="breadcrumbs"><a href="1_4_9_0.html" title="Backing up projects with Auto Save">Previous</a> | <a href="1_4_10_1.html" title="Types of scratch disks">Next</a> | <a href="#top">Top</a> | <a href="1_4_0_0.html">Starting and Working with Projects</a></div></td></tr></table>
