I assume this question is about some of the file managers of RadEditor (ImageManager, DocumentManager, etc.). All these managers are using RadFileExplorer
to achieve the file browsing functionality. In order to modify this functionality you need to modify the built-in dialog FileBrowser.ascx
which will affect all managers. Example of how to modify built-in dialogs is available here
RadFileExplorer has a property EnableCreateNewFolder
which set to false
will disable creating new folder in a folder that has Upload permissions. In order to enable folder creation in a folder without Upload permissions you need to create a custom content provider and implement such logic. You can find information on the subject in this article: Using custom FileBrowserContentProvider
