- Device & OS
- Windows
- Scenario
- Attempting to open a PES embroidery file by double-clicking it in Windows File Explorer.
- Observed behavior
- PES files are opening in Adobe Acrobat instead of the correct embroidery application.
Verify that your preferred embroidery software is successfully installed on your computer so it can be selected as the default application.
Use the Open With Context Menu
This is the quickest way to correct file associations directly from the file itself.
By using the right-click context menu, you can force Windows to remember your application preference for any specific file type.
Locate any PES file on your computer, right-click on it, and select 'Open With' from the dropdown menu.
Click on 'Choose another app' to open the application selection dialog.
Find your embroidery software in the list. If it is not listed, click 'More apps' or 'Look for another app on this PC' to browse to its installation folder.
Check the box that says 'Always use this app to open .pes files' and click 'OK'.

Modify Default Apps in Windows Settings
Use the main Windows Settings menu to manage file associations if the context menu method does not work.
Manage All Your Documents with WPS Office
While embroidery files require specialized software, managing your everyday PDFs, documents, spreadsheets, and presentations is easier with WPS Office. As a free, lightweight, and highly compatible alternative to Microsoft Office, WPS prevents common file association conflicts and offers a seamless experience.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation file.
- 2. Run the Setup: Open the downloaded file and follow the quick on-screen instructions to install.
- 3. Set Default Programs: During setup, you can easily choose to set WPS as your default app for Word, Excel, and PDF formats without affecting specialized files like PES.
