Previewing Files

Opndrive supports two ways to preview a file, depending on whether you want to stay in context or open it somewhere shareable.

	Modal preview	Route preview
How to open it	Click a file	“Open in new tab” from the file menu
URL	Stays on the current page	`/dashboard/preview/{etag}?key=...`
Navigation	Prev/next arrows between files	Single file, no prev/next
Shareable	No	Yes - it’s a real, bookmarkable URL

Supported file types include images, PDFs, video, audio, text/code, and spreadsheets.

Route Preview and File Versions

The route preview URL is built from the file’s S3 ETag, not just its path. If the file changes after you copy the link, opening it again will detect the ETag no longer matches and show an error rather than silently serving the new version under the old link - the link is to a specific version of the file, not to “whatever is at this path now.”

See Preview Architecture for how the two preview modes share components and how the route is authenticated.
