Jungle Disk supports native mapping of a local drive letter to your Jungle Disk under Windows XP, Server 2003, and Vista. This page contains important information about how drive mapping works and potential issues to look out for.

Local drive mapping is configured via the "Network Drive" option under the in the configuration dialog. You can select any available drive letter, and Jungle Disk will automatically map the drive on startup and unmap the drive on shutdown.
 
Drive mapping relies on the "WebClient" service which must be installed and running for drive mapping to work. If the Web Client service is disabled, you will get an error message stating: "Drive Mapping Failed - The network is not present or not started". To start the WebClient service, right click on "My Computer" on your start menu, select "Manage" and locate the service under the "Services" item in the tree.

Important Note on Windows Explorer: When browsing your mapped disk through Windows Explorer, Windows will automatically attempt to download some files. In the standard icon view, this includes all EXE files, as it tries to obtain the icon from the file. This may be an issue for directories that have large executable files in them (e.g. large installers), as it can cause excessive download traffic. Some files, such as graphic, music, or video files, may also be downloaded when you select the file, mouse over them, or use the "Thumbnail" view in Explorer as Windows tries to open the file to obtain a preview or metadata information.
If excessive downloads become an issue, these suggestions may help:

• Use a large local cache (the default size is 1GB, and can be changed in the Jungle Disk Options). Once a file has been stored in the cache, it will not be re-downloaded, even if Explorer requests the file multiple times
• Use the My Jungle Disk (Web Folders) view to browse your disk, instead of the mapped drive. The Web Folders view will not download any files until you open or copy them to the local machine

There are several different error messages you may see if drive mapping fails. The list below provides some common issues and solutions.

• Persisting modification times for Windows XP mapped drives requires installing this hotfix from Microsoft.
• If you get a Drive Mapping Error that says "The network path was not found" make sure you have the latest Windows XP SP2 security updates installed. Also, make sure a local firewall is not blocking access.
• It appears there is an issue with Windows Server 2003 / IIS6 bound to port 80 that causes Jungle Disk to be unable to bind the port. It does not appear to affect Windows XP or IIS5.1.
  Please visit the Port 80 Workarounds article for further guidance.
• If you get a Drive Mapping Error that says "The workstation driver is not installed" when mapping a drive you need to reboot your machine to complete the installation.
• "A device attached to the system is not functioning" when mapping a drive may be caused by certain firewall or anti-virus products (this is known to occur with Kaspersky's Anti-Virus HTTP filtering feature - see this forum post for a fix)
• "The network is not present or not started" when mapping a drive may be caused by running under the "guest" windows account.
• If you have configured Internet Explorer to use a Proxy server, you must add "localxp.jungledisk.com" (on XP) or "local.jungledisk.com" (on Vista) to the Exception list (under Advanced) then reboot for Windows to connect correctly to Jungle Disk
• Windows Vista handles some directory names with URL-encoded characters (such as %2E) in them incorrectly. You may not be able to browse into these directories via the mapped drive
• When copying large directories from the Jungle Disk mapped drive, you may receive a "Parameter Incorrect" error from Windows. The "retry" button should allow the copy to continue.

Several important registry changes are required for Drive Mapping to function properly. These changes are made automatically by the Jungle Disk installer and you may be asekd to reboot your machine for the changes to take effect. Jungle Disk checks for these settings on startup when drive mapping is enabled, and will reset them if needed.
The specific changes are listed below for your information:

• FileSizeLimitInBytes
  By default, the WebClient service will not work with files >50MB in size. Jungle Disk changes this limit to 4GB. For more details from Microsoft see: http://support.microsoft.com/default.aspx/kb/900900/.
   
  
• FileAttributesLimitInBytes
  By default, the WebClient service is limited to directories with 1000 files or less. Jungle Disk changes this limit to support directories with several thousand files in them. For more details from Microsoft see: http://support.microsoft.com/?kbid=912152.
