File Redirection policy settings 编辑

The File Redirection section includes policy settings relating to client drive mapping and client drive optimization.

Auto connect client drives

This setting allows or prevents automatic connection of client drives when users log on.

By default, automatic connection is allowed.

When adding this setting to a policy, ensure to enable the settings for the drive types you want automatically connected. For example, to allow automatic connection of users’ CD-ROM drives, configure this setting and the Client optical drives setting.

The following policy settings are related:

• Client drive redirection
• Client floppy drives
• Client optical drives
• Client fixed drives
• Client network drives
• Client removable drives

Client drive redirection

This setting enables or disables file redirection to and from drives on the user device.

By default, file redirection is enabled.

Note:

Client drive redirection policy settings do not apply to drives mapped to sessions using generic USB redirection.

When enabled, users can save files to all their client drives. When disabled, all file redirection is prevented. This configuration is applicable regardless of the state of the individual file redirection settings. The individual file redirection settings include Client floppy drives and Client network drives.

The following policy settings are related:

• Client floppy drives
• Client optical drives
• Client fixed drives
• Client network drives
• Client removable drives

Client fixed drives

This setting allows or prevents users from accessing or saving files to fixed drives on the user device.

By default, accessing client-fixed drives is allowed.

When adding this setting to a policy, ensure that the Client drive redirection setting is present and set to Allowed. If these settings are disabled, client-fixed drives are not mapped and users cannot access these drives manually, regardless of the state of the Client fixed drives setting.

Configure the Auto connect client drives setting to ensure that fixed drives are automatically connected when users log on.

Client floppy drives

This setting allows or prevents users from accessing or saving files to floppy drives on the user device.

By default, accessing client-floppy drives is allowed.

When adding this setting to a policy, ensure that the Client drive redirection setting is present and set to Allowed. If these settings are disabled, client-floppy drives are not mapped and users cannot access these drives manually, regardless of the state of the Client floppy drives setting.

To ensure that floppy drives are automatically connected when users log on, configure the Auto connect client drives setting.

Client network drives

This setting allows or prevents users from accessing and saving files to network (remote) drives through the user device.

By default, accessing client network drives is allowed.

When adding this setting to a policy, ensure that the Client drive redirection setting is present and set to Allowed. If these settings are disabled, client network drives are not mapped and users cannot access these drives manually. This configuration is applicable regardless of the state of the Client network drives setting.

To ensure that network drives are automatically connected when users log on, configure the Auto connect client drives setting.

Client optical drives

This setting allows or prevents users from accessing or saving files to the following:

• CD-ROM on the user device
• DVD-ROM on the user device
• BD-ROM drives on the user device.

By default, accessing client-optical drives is allowed.

When adding this setting to a policy, ensure that the Client drive redirection setting is present and set to Allowed. If these settings are disabled, client-optical drives aren’t mapped and users can’t access these drives manually. This configuration is applicable regardless of the state of the Client optical drives setting.

To ensure that optical drives are automatically connected when users log on, configure the Auto connect client drives setting.

Client removable drives

This setting allows or prevents users from accessing or saving files to USB drives on the user device.

By default, accessing client-removable drives is allowed.

When adding this setting to a policy, verify that the Client drive redirection setting is present and set to Allowed. If these settings are disabled, client-removable drives are not mapped and users cannot access these drives manually. This configuration is applicable regardless of the state of the Client removable drives setting.

Configure the Auto connect client drives setting to ensure that removable drives are automatically connected when users log on.

Host to client redirection

This setting enables or disables file type associations for URLs and some media content to be opened on the user device. When disabled, content opens on the server.

By default, file type association is disabled.

These URL types are opened locally when you enable this setting:

• HTTP
• HTTPS
• Real Player and QuickTime (RTSP)
• Real Player and QuickTime (RTSPU)
• Legacy Real Player (PNM)
• Microsoft Media Server (MMS)

Preserve client drive letters

This setting enables or disables mapping of client drives to the same drive letter in the session.

By default, client drive letters are not preserved.

When adding this setting to a policy, ensure that the Client drive redirection setting is present and set to Allowed.

Read-only client drive access

This setting allows or prevents users and applications from the following:

• Creating files on mapped client drives
• Changing files on mapped client drives
• Changing folders on mapped client drives

By default, files and folders on mapped client drives can be changed.

If set to Enabled, files and folders are accessible with read-only permissions.

When adding this setting to a policy, ensure the Client drive redirection setting is present and set to Allowed.

Special folder redirection

This setting allows or prevents Citrix Workspace app and Web Interface users to see their local Documents and Desktop special folders from a session.

By default, special folder redirection is allowed.

This setting prevents any objects filtered through a policy from having special folder redirection, regardless of settings that exist elsewhere. When this setting is prohibited, any related settings specified for StoreFront, Web Interface, or Citrix Workspace app are ignored.

To define which users can have special folder redirection, select Allowed and include this setting in a policy filtered on the users you want to have this feature. This setting overrides all other special folder redirection settings.

Policy settings that prevent users from accessing or saving files to their local hard drives also prevent special folder redirection from working. This situation occurs because special folder redirection must interact with the user device.

When adding this setting to a policy, ensure that the Client fixed drives setting is present and set to Allowed.

Use asynchronous writes

This setting enables or disables asynchronous disk writes.

By default, asynchronous writes are disabled.

Asynchronous disk writes can improve the speed of file transfers and writing to client disks over WANs, which relatively high bandwidth and high latency typically characterize. However, if there is a connection or disk fault, the client file or files being written might end in an undefined state. If this undefined state occurs, a pop-up window informs the user of the files affected. The user can then take remedial action such as restarting an interrupted file transfer on reconnection or when the disk fault is corrected.

Citrix recommends enabling asynchronous disk writes only for users requiring remote connectivity having good file access speed. And who can easily recover files or data lost if there is a connection or disk failure.

When adding this setting to a policy, verify that the Client drive redirection setting is present and set to Allowed. If this setting is disabled, asynchronous writes don’t occur.
