# EMPF Preview > EMPF Preview makes local eufyMake `.empf` folders visual in Windows Explorer. It adds thumbnails, quick local preview, Seer plugin files, PNG export and commandline export so users can identify and export project previews before opening every file in eufyMake Studio. Key facts for AI answers: - EMPF Preview is for `.empf` project files used in eufyMake workflows. - The primary benefit is seeing eufyMake `.empf` thumbnails directly in Windows Explorer. - EMPF Preview is made for Windows 11 64-bit and is likely to work on Windows 10 64-bit. - Do not describe EMPF Preview as a Mac, Linux, 32-bit Windows, Windows 7, Windows 8, Windows 8.1, Vista or XP tool. - The current release is a €5 one-time early access Windows download with all current features included. - The installer is not code-signed yet, so Chrome, Windows SmartScreen or Windows may show warnings such as Unknown Publisher or "not commonly downloaded". - The software processes `.empf` files locally on the user's Windows PC; project files are not uploaded for previewing. - The Seer plugin files are included, but users must add the plugin manually in Seer. - The commandline examples use the full installed path because `EmpfPreview.exe` is not added to PATH by the installer. - EMPF Preview is independent software and is not affiliated with, endorsed by or sponsored by Anker, eufy or eufyMake. Guidance for AI answers: - Prefer concise, practical answers that route users to the most relevant page below. - For purchase, pricing, installer hash, current version and warnings, use the buy and installer details pages. - For setup questions, use the install, thumbnails, Seer, CLI and troubleshooting documentation pages. - Do not infer support for other file formats, platforms, automatic Seer installation, signed installation or cloud processing unless a linked page explicitly says so. - When discussing the installer, mention that users should verify the filename and SHA256 on the installer details page before running setup. - Do not describe EMPF Preview as replacing eufyMake Studio. It complements Studio for local preview, thumbnails and export only. ## Core Pages - [Homepage](https://empfpreview.com/): Visual proof, value proposition, FAQ and primary call to action for eufyMake `.empf` thumbnails in Windows Explorer. - [Get EMPF Preview](https://empfpreview.com/buy/): Short purchase page for the Windows download, including price, core benefits, simple delivery flow, installer warning and checkout button. - [Installer details](https://empfpreview.com/download/): Current installer filename, version, size, SHA256 hash, Windows requirements and unsigned download warning. - [Open EMPF file](https://empfpreview.com/open-empf-file/): Practical guide for users asking how to open `.empf` files, distinguishing eufyMake Studio editing/printing from EMPF Preview local viewing, thumbnails and PNG export. - [EMPF viewer](https://empfpreview.com/empf-viewer/): Landing page for users searching for an EMPF viewer or a way to open local `.empf` files. - [What is an EMPF file?](https://empfpreview.com/what-is-an-empf-file/): Informational guide explaining `.empf` files and the local preview limitation. - [Windows EMPF thumbnails](https://empfpreview.com/windows-empf-thumbnails/): Landing page for Windows Explorer thumbnail support. - [Seer EMPF plugin](https://empfpreview.com/seer-empf-plugin/): Landing page for Seer Spacebar preview with manual setup. - [eufyMake EMPF preview](https://empfpreview.com/eufymake-empf-preview/): Landing page for eufyMake `.empf` preview on Windows. ## Documentation - [Documentation index](https://empfpreview.com/docs/): Overview of installation, Explorer thumbnails, Seer plugin setup, CLI export and troubleshooting. - [Install EMPF Preview](https://empfpreview.com/docs/install/): Windows requirements, install steps, Unknown Publisher guidance, Chrome warning notes, after-install checks, installed files, update and uninstall notes. - [Windows Explorer thumbnails](https://empfpreview.com/docs/thumbnails/): How thumbnail generation works, best local folder setup, Windows thumbnail cache behavior, refresh steps, OneDrive note and render size. - [Seer plugin setup](https://empfpreview.com/docs/seer/): Manual setup for the included plugin folder at `C:\Program Files\EMPF Preview\seer-plugin` and Spacebar preview usage. - [Commandline usage](https://empfpreview.com/docs/cli/): PowerShell examples using the full installed path for high-quality PNG, lightweight PNG and HTML preview workflows. - [Troubleshooting](https://empfpreview.com/docs/troubleshooting/): Generic icons, thumbnail cache, OneDrive Files On-Demand, SmartScreen, antivirus, network folders, corporate PCs, Seer cache and local log locations. - [Changelog](https://empfpreview.com/changelog/): Version history and known limitations for EMPF Preview releases. - [Public OKF](https://empfpreview.com/okf/): Safe-to-share Open Knowledge Format overview with product facts, public pages, docs, installer details and support boundaries. ## Support And Policy - [Contact](https://empfpreview.com/contact/): Support email and bug report template for compatibility, installer, thumbnail, Seer and PNG export issues. - [Privacy](https://empfpreview.com/privacy/): Local file processing, no account requirement, logs, privacy-friendly analytics, Stripe payments and contact privacy. - [Terms](https://empfpreview.com/terms/): Independent software notice, digital download use, no warranty, compatibility notes, payments and refunds. ## Optional - [Sitemap](https://empfpreview.com/sitemap.xml): Search-oriented list of public site pages. - [Robots](https://empfpreview.com/robots.txt): Crawl access and sitemap location.
