To customize the drag and drop UI in your application, you can use the DragEventArgs.DragUIOverride property to set custom captions and glyphs. However, if you are experiencing issues with the size of the drag and drop icons in File Explorer specifically, there may not be a direct way to adjust this through standard settings or properties, especially on a work computer where administrative privileges may be limited.
If the icons are excessively large, it might be related to the system's display settings or the specific configuration of the File Explorer. Here are a few suggestions you might consider:
- Check Display Settings: Ensure that your display settings are set to a scaling that works for you. Sometimes, adjusting the resolution or scaling can impact how elements are displayed.
- Reset File Explorer Settings: You mentioned you have reset File Explorer, but ensure that you have also checked for any updates or additional settings that could affect its behavior.
- Feedback to IT: Since you are on a work computer, it might be worth discussing this issue with your IT department. They may have specific configurations or policies in place that could be affecting the drag and drop functionality.
Unfortunately, without the ability to install third-party applications or perform system scans, your options may be limited. If the issue persists, consider providing feedback to Microsoft through the Feedback Hub, as user feedback can influence future updates and features.
