Windows® Embedded 8 Standard for HP Thin Clients Quick Reference Guide

Local drives
The following sections describe the local drives located on the thin client. In the modern UI, type
Computer and click the Computer tile.
Drive Z
Drive Z is the onboard volatile memory (RAMDRIVE) on the logic board of the thin client. HP
recommends that you do not use this drive to save data that you want to retain. For RAMDisk
configuration instructions, see
HP RAMDisk Manager on page 18. For information about using the Z
drive for roaming profiles, see
Roaming profiles on page 9.
Drive C and flash
Drive C is in the onboard flash drive. HP recommends that you do not allow the free space on Drive C
to drop below 10% of the flash size.
A write filter is used by the thin client for security and to prevent excessive flash write activity.
Changes to the thin client configuration are lost when the thin client is restarted unless the write filter
is disabled. See
HP Unified Write Filter on page 16 for instructions to disable the cache. Enable the
write filter when you do not want permanent changes.
Saving files
CAUTION: The thin client uses an embedded operating system with a fixed amount of flash
memory. HP recommends that you save files that you want to retain on a server rather than on the
thin client. Be careful of application settings that write to the C drive, which resides in flash memory
(in particular, many applications by default write cache files to the C drive on the local system). If you
must write to a local drive, change the application settings to use the Z drive. To minimize writing to
the C drive, update configuration settings as described in
User accounts on page 10.
Mapping network drives
You must be logged on as Administrator to map network drives.
To retain the mappings after the thin client is restarted:
1. Disable the write filter cache during the current boot session.
2. Select Reconnect at Logon.
You can also assign the remote home directory by using a user manager utility.
Roaming profiles
Write roaming profiles to the C drive. The profiles need to be limited in size and will not be retained
when the thin client is rebooted.
NOTE: For roaming profiles to work and be downloaded, there must be sufficient flash space
available. In some cases, it may be necessary to remove software components to free up space for
roaming profiles.
