## Preview a File Clicking a file from Files Home or in a related list opens the File Previewer, which lets you view the file without downloading it. Use the arrow keys in the previewer to see each page, zoom in or out, or change the preview width and screen size. Files can be previewed by the file owner and anyone with access to the file. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-collaboration-264-0-0-production-enus/1aab5b5e-c990-4b8c-840a-6fb18af49709/images/icon_note.png) Note - Only the first 500 pages of very large files are rendered in the preview. If your org has migrated to Hyperforce, only the first 100 pages may be rendered in the preview. - You can’t preview files larger than 25 MB or 500 pages, unknown file types, password-protected files, and copy-protected PDFs. - For files that you can’t preview, the **Preview** option isn’t available on feeds or list views, and files appear as generic file type icons in the feed. - Some Microsoft Office 2007 features don’t display correctly in previews. - Some extended characters, such as ellipsis, and formatting can appear inconsistently in previews. - If a file can be previewed, but a preview doesn’t exist, contact your Salesforce admin to request to regenerate the preview. - In the file previewer, the heading overlay menu disappears after 5 seconds of inactivity. Move the mouse or press tab to make the menu reappear. - Previews for CMS images and files aren’t visible in Firefox when the browser security is set to standard. This occurs because the standard Firefox security policy blocks third-party domain cookies. To preview CMS content set the security policy to custom and allow cookies. For the complete list of file types that Salesforce File Preview supports, see [Supported File Preview Formats](https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/connect_resources_files_preview_format.htm). ## View and Edit File Details in Lightning Experience Click View File Details from a file preview or from the actions menu on Files home, in the feed, or on a record.
