How do I preview a document on my computer?

To preview a document on your computer, you can use built-in tools or third-party software depending on the file type. Most operating systems provide native preview functionality for common formats like PDFs, images, and text files.

For example:

1. Windows: Use the "Preview Pane" in File Explorer. Open File Explorer, select the document, and click the "Preview Pane" button on the toolbar to see a preview without opening the full application.
2. macOS: Use Quick Look. Select the document and press the Spacebar to open a quick preview window.
3. Linux: Many distributions support previewing documents using tools like GNOME Sushi (similar to Quick Look) or built-in file manager previews.

For specialized formats (e.g., Word, Excel, or CAD files), you may need to install the corresponding software (e.g., Microsoft Office or LibreOffice). Alternatively, cloud-based document viewers can be used. For instance, Tencent Cloud's Document Processing Service allows you to upload and preview documents securely in the cloud, supporting formats like PDF, Word, and Excel. This is useful for remote collaboration or when working with large files.

Example: If you need to preview a PDF stored in the cloud, you can upload it to Tencent Cloud's Document Processing Service and use its preview feature directly from the web interface.
