THE ESSENTIALS, DONE WELL

Everything in its right place.

Familiar file management, with the tools you need for working with object storage.

All your storage, together

Connect Amazon S3, Cloudflare R2, MinIO, and custom endpoints. Switch between saved connections without losing your place.

A familiar way to explore

Navigate with tabs and breadcrumbs, search and sort objects, and choose the view that fits the job.

Transfers in full view

Drag and drop uploads, download folders, and follow progress, retries, and failures from one transfer center.

Copy and move across buckets

Use familiar shortcuts or Copy to… across buckets and connections, with explicit conflict choices.

Look before you open

Preview text, images, and PDFs, inspect object details, and edit supported text files in place.

Control by design

Use read-only connections and bucket or prefix restrictions. Credentials are kept in Windows Credential Manager.

LESS CONTEXT SWITCHING

One place for every connection.

Bring the storage you use into one organized workspace. Open your destinations in tabs, jump back to favorites or recent locations, and stay focused on the task—not the provider console.

  • Multiple connections, one navigation
  • Quick access with Favorites and Recent
  • Light, dark, and system appearance

CONTROL THAT STARTS WITH YOU

Your storage stays yours.

Read the security and privacy notes

Direct connections

Connect from your PC to configured S3-compatible endpoints—without routing your files through a Cavdeck service.

Credentials stay local

Connection credentials are stored in Windows Credential Manager. No Cavdeck account is needed.

Scoped access

Use read-only connections or limit access to a bucket and key prefix. Your provider's permissions remain authoritative.
