Abstract: Techniques presented herein provide an approach for sharing folders and files across devices. In one embodiment, folder redirection is employed to permit a device running a virtual infrastructure (VDI) client which connects to a remote agent to access folders and files shared by other devices. To enable such folder redirection, a folder redirection management module generates, for each shared folder, a redirection mapping that associates an original folder path with a uniform naming convention (UNC) scheme. When a device attempts to launch a remote desktop in a remote agent using the same username as that associated with other devices that share folders/files, the folder redirection management module transmits redirection mappings for those devices to the remote agent and opens permissions of the corresponding UNC schemes, the remote agent mounts the shared folders as virtual drives, and the shared folders are then accessible through folder redirection based on the redirection mappings.
