KIO S3 integrates Amazon S3 and S3-compatible object storage with KDE applications.
It is a KIO worker, allowing applications such as Dolphin, Kate and Gwenview to access S3 buckets and objects using the same interfaces they use for local and network files.
Users can browse buckets, upload and download files, create folders and perform common file-management operations without needing a separate S3 client.
This is free and open source software.
Key Features
- Access Amazon S3 buckets directly from KIO-aware applications.
- Work with S3-compatible services such as MinIO and Cloudflare R2.
- Browse buckets and objects from Dolphin and other KDE applications.
- Upload files and folders to buckets.
- Delete objects from buckets.
- Copy, move and rename objects and folders.
- Access storage using
s3://URLs. - Support multipart uploads and streaming downloads for large files.
