KDE names Dolphin, Kate, and Gwenview as examples. It is Linux software—not a storage provider—and support for any particular non-Amazon S3-compatible service should be confirmed before you rely on it.
What KIO S3 does
KDE describes KIO S3 as a way for KIO-aware applications to “access and edit Amazon S3 buckets and objects.” In practice, it connects those applications to object storage so you can work with S3 content from a familiar app rather than treating KIO S3 as a cloud-storage service of its own. KDE lists Dolphin, Kate, and Gwenview as examples, and also names Konqueror and Krusader among the applications it extends. KDE’s KIO S3 application page identifies the software as Linux software and licenses it under GPL-2.0-or-later.

How to install KIO S3 on Linux
KDE directs users to install KIO S3 through Discover, another AppStream store, or their Linux distribution’s package manager. Availability and the package’s current version can depend on your distribution and its repositories.
- Open Discover, another AppStream software store, or your distribution’s package manager.
- Search for KIO S3 and install the package offered for your system.
- Open a KIO-aware application, such as Dolphin, Kate, or Gwenview, and follow the project’s handbook or your provider’s instructions to configure access.
The KDE page links to a KIO S3 Handbook. Consult the current handbook for connection details; installation alone does not establish which endpoint, authentication method, or settings a particular storage service requires.

How to access an Amazon S3 bucket in Dolphin
Once KIO S3 is installed, KDE’s stated purpose is to let KIO-aware applications access and edit S3 buckets and objects. Dolphin is one of the applications KDE names. The available product-page information does not establish an exact address format, credential-entry path, or sequence of Dolphin UI actions, so use the handbook and AWS configuration details rather than guessing a URL or assuming a particular setup flow.
Amazon S3 stores objects under keys and exposes a REST interface. AWS documents strong read-after-write consistency for writes and listings; that describes Amazon S3, not every service that implements an S3-compatible API. AWS’s S3 FAQ and S3 feature page provide service-specific details.

Does KIO S3 work with S3-compatible storage?
Do not assume that the phrase “S3-compatible” guarantees a connection. KDE’s product page specifically describes access to Amazon S3 and does not identify third-party providers or document compatibility boundaries for endpoints, authentication, or individual operations. Before depending on another provider, confirm its KIO S3 support and required settings in the handbook or project documentation, and check the provider’s own API guidance.
What changed in the latest listed release?
KDE lists KIO S3 version 1.0.2, dated April 23, 2026, as its latest release. KDE says it improves large-file handling by refining multipart-upload chunking and streaming downloaded files instead of buffering them in memory. The release history also lists version 1.0.1, dated March 24, 2026, with fixes for renaming S3 profiles and more standard mkdir operations, and version 1.0.0, dated March 13, 2026, as the initial release. These are the releases listed on KDE’s page; your distribution may package a different version.

- You use Linux and want S3 access from a KIO-aware KDE application such as Dolphin, Kate, or Gwenview.
- Your distribution provides the package, or you can install it through an AppStream store.

If the provider is not Amazon S3, verify compatibility first. The available KDE product information does not establish provider breadth, credentials handling, or feature parity across services.
