Open an archive: https://toolster.net/unrar_files
Before unpacking a RAR, check its contents. This walkthrough opens a small garden-planning archive, previews a note and a picture, then saves a single picture through the Save As dialog.
Choose archive opens the file picker. The list shows the folders, filenames and sizes. Select an item to look at it, then use Save file for that item. Extract all is available when you want the complete folder instead.
The pictures and notes in the example were made for this walkthrough. Use files you trust; seeing a filename in an archive does not establish that it is safe to run.
For a ZIP archive, the separate ZIP walkthrough shows the same one-file task: https://youtu.be/zLc7Fs6wtjw
