IFileSystemProvider

Wisej.Core.IFileSystemProvider

Namespace: Wisej.Core

Assembly: Wisej.Framework (3.5.0.0)

Abstracts access to the file system. Implementations of this interface are used by the file dialogs and other components that need to interact with the file system. Wisej provides the built-in default implementation for the standard disk-based file system and a number of alternative implementations in the Wisej extensions, such as: Amazon S3, Google Drive, and Microsoft OneDrive.
