Breadcrumbs & Thumbnails

The File Manager ships with an integrated Breadcrumb UI element, designed to indicate the location of file within a folder hierarchy. Users can navigate the folder hierarchy via the Breadcrumb or use the Treeview instead.

Multiple options give end-users total control over the layout of the File Manager's Detail View. Columns can be resized, dragged to different locations and sorted as neeeded.

Access & Permissions

Access & Permissions

Our ASP.NET File Manager makes it easy to control file/folder Access & Permissions. You can define permissions using access rules via the SettingsPermissions.AccessRules collection.

You can create access rules for folders (including files and child folders) and individual files using FileManagerFolderAccessRule and FileManagerFileAccessRule elements. In addition, you can associate any number of access rules with specific security roles to group related permissions together.
