File System Settings (Compact 2013)

File system settings for Storage Manager follow a two-tier hierarchy.

  • Generic file system settings under the root file system key
    Settings placed at the root file system key, [HKLM\System\StorageManager\<FileSystemName>], apply to every mounted instance of <FileSystemName>. These settings provide values that apply to all profiles and to all auto-load systems.
  • Profile-specific file system settings under the profile file system sub-key
    Settings at the profile file system sub-key, [HKLM\System\StorageManager\Profiles\<MyProfileName>\<FileSystemName>], are profile-specific. That is, settings at this level pertain only to mounted instances of <FileSystemName> on devices reporting the profile <MyProfileName>.

The following table shows the registry settings for any file system that can be set at the root file system level

HKEY_LOCAL_MACHINE\System\StorageManager\<myFSD>.

Registry value: Type

Description

Paging: REG_DWORD

Controls paging.

  • 0 - Disables paging
  • 1 - Enables paging

Util: REG_SZ

Specifies the DLL name of utility to do format and scan.

MountFlags: REG_DWORD

This value is deprecated. For replacement values, see Mount Settings.

Dll: REG_SZ

Specifies the name of the file system DLL.

LockIoBuffers: REG_DWORD

Set to 1 (default) to indicate that the FSD Manager should call LockPages to page-in all input/output buffers.

Set to 0 only if the file system driver performs all necessary I/O buffering.

PowerNotify: REG_DWORD

Set to 1 (default) to indicate that the file system driver should be powered down on suspend.

This setting indicates that the FSD Manager should block any suspend and power-down until all threads exit the FSD, and call MyFSD_Notify when suspend and resume events occur.

In addition to settings that can be applied to any file system, there are a number of settings at the HKEY_LOCAL_MACHINE\System\StorageManager\<myFSD> level that apply only a specific kind of file system, such as FATFS, BINFS, and so on. For more information, see Settings for Specific File Systems.

The following topics provide information about settings that you can use only with a specific file system:
