Virtual software layer attributes

The attributes section contains the layer attributes for the registry redirection area. You can view these attributes at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FSLX\Parameters\FSL. In this directory each layer has a numbered folder. The following table lists and describes the different attributes:

Warning:

Do not modify these attributes in the registry.

Table: Layer attributes

Attribute

Description

ActivateTime

The date and time when the sublayer was last activated (value = binary_date_time). This attribute is updated when Activate is called or when the computer starts if the layer is ActiveOnStart.

Active

The sublayer is currently inactive (value = 0) or the sublayer is active (value = 1). Activate sets this value to 1. Deactivate sets this value to 0.

ActiveOnStart

The sublayer is active on system start (value = 1). You change this value by setting a layer to start automatically.

See Configuring a virtual software layer to start automatically.

CreateTime

The date and time at which the layer was created (value = binary_date_time).

Enabled

Deprecated entry, not used.

FileRedirect

The path to the sublayer's file redirection area (value = Root:\Fslrdr\sublayer_folder_number). The files for the layer are stored here.

Flags

A value that represents the layer type. The value is a decimal value of a five bit hex value. The value of each bit represents a different type. For example, if the layer is a data layer, the value of the first bit is 1.

ID

The sublayer's GUID (value = GUID). You can use the SVSCMD executable file with the SETGUID parameter to change this value.

MajorVersion

Combines with MinorVersion to indicate the sublayer's format: either (value = 0), (value = 1), or (value = 2). Different major versions are usually not compatible.

MinorVersion

Combines with MajorVersion to indicate the sublayer's format: either (value = 0), (value = 1), or (value = 2). Different minor versions are usually compatible. Internal layer upgrades are applied to move a minor version to the current version. This process is not reversible.

Name

The layer's name (value = layer_name). The visual name of the layer. You can change a layer's name in the SWV Admin tool or with the SVSCMD executable file.

PeerID

The GUID for the sublayer's companion sublayer (value = companion_sublayer's_guid). This attribute is used to link the read-only sublayer to the writeable sublayer and vice versa. You indirectly change this value with the SVSCMD executable file and the SETGUID parameter.

ReadOnly

The sublayer's writeable status; either read-only (value = 1) or writeable (value = 0).

RefreshTime

The date and time at which the layer was last reset (value = binary_date_time). This value is indirectly changed when a layer is reset.

RegRedirect

The location of the layer's registry data (value = SOFTWARE\fslrdr\sublayer_folder_number). The registry entries for a layer are stored here.

ShouldDelete

(Optional) Set value = 1 to delete this layer. The layer is deleted after this value is checked.

Type

The layer's type: application (value=0), peer (value=1), data (value=2).
