Overview of the Projected File System technology.
To develop Projected File System, you need these headers:
For programming guidance for this technology, see:
PRJ_CALLBACK_DATA_FLAGS Flags controlling what is returned in the enumeration. |
PRJ_COMPLETE_COMMAND_TYPE Specifies command types. |
PRJ_EXT_INFO_TYPE Specifies extended information types |
PRJ_FILE_STATE The state of an item. |
PRJ_NOTIFICATION A notification value specified when sending the notification in a callback. |
PRJ_NOTIFY_TYPES Types of notifications describing a change to the file or folder. |
PRJ_PLACEHOLDER_ID Defines the length of a placeholder identifier. |
PRJ_STARTVIRTUALIZING_FLAGS Flags to provide when starting a virtualization instance. |
PRJ_UPDATE_FAILURE_CAUSES Descriptions for the reason an update failed. |
PRJ_UPDATE_TYPES Flags to specify whether updates will be allowed given the state of a file or directory on disk. |
PRJ_CANCEL_COMMAND_CB Notifies the provider that an operation by an earlier invocation of a callback should be canceled. |
PRJ_END_DIRECTORY_ENUMERATION_CB Informs the provider that a directory enumeration is over. |
PRJ_GET_DIRECTORY_ENUMERATION_CB Requests directory enumeration information from the provider. |
PRJ_GET_FILE_DATA_CB Requests the contents of a file's primary data stream. |
PRJ_GET_PLACEHOLDER_INFO_CB Requests information for a file or directory from the provider. |
PRJ_NOTIFICATION_CB Delivers notifications to the provider about file system operations. |
PRJ_QUERY_FILE_NAME_CB Determines whether a given file path exists in the provider's backing store. |
PRJ_START_DIRECTORY_ENUMERATION_CB Informs the provider that a directory enumeration is starting. |
PrjAllocateAlignedBuffer Allocates a buffer that meets the memory alignment requirements of the virtualization instance's storage device. |
PrjClearNegativePathCache Purges the virtualization instance's negative path cache, if it is active. |
PrjCompleteCommand Indicates that the provider has completed processing a callback from which it had previously returned HRESULT_FROM_WIN32(ERROR_IO_PENDING). |
PrjDeleteFile Enables a provider to delete an item that has been cached on the local file system. |
PrjDoesNameContainWildCards Determines whether a name contains wildcard characters. |
PrjFileNameCompare Compares two file names and returns a value that indicates their relative collation order. |
PrjFileNameMatch Determines whether a file name matches a search pattern. |
PrjFillDirEntryBuffer Provides information for one file or directory to an enumeration. |
PrjFillDirEntryBuffer2 Provides information for one file or directory to an enumeration and allows the caller to specify extended information. |
PrjFreeAlignedBuffer Frees an allocated buffer. |
PrjGetOnDiskFileState Gets the on-disk file state for a file or directory. |
PrjGetVirtualizationInstanceInfo Retrieves information about the virtualization instance. |
PrjMarkDirectoryAsPlaceholder Converts an existing directory to a directory placeholder. |
PrjStartVirtualizing Configures a ProjFS virtualization instance and starts it, making it available to service I/O and invoke callbacks on the provider. |
PrjStopVirtualizing Stops a running ProjFS virtualization instance, making it unavailable to service I/O or involve callbacks on the provider. |
PrjUpdateFileIfNeeded Enables a provider to update an item that has been cached on the local file system. |
PrjWriteFileData The PrjWriteFileData function provides the data requested in an invocation of the PRJ_GET_FILE_DATA_CB callback. (PrjWriteFileData) |
PrjWritePlaceholderInfo Sends file or directory metadata to ProjFS. |
PrjWritePlaceholderInfo2 Sends file or directory metadata to ProjFS and allows the caller to specify extended information. |
PRJ_CALLBACK_DATA Defines the standard information passed to a provider for every operation callback. |
PRJ_CALLBACKS A set of callback routines to where the provider stores its implementation of the callback. |
PRJ_COMPLETE_COMMAND_EXTENDED_PARAMETERS Specifies parameters required for completing certain callbacks. |
PRJ_EXTENDED_INFO Specifies optional extended information for directory enumeration and placeholder information. |
PRJ_FILE_BASIC_INFO Basic information about an item. |
PRJ_NOTIFICATION_MAPPING Describes a notification mapping, which is a pairing between a directory (referred to as a "notification root") and a set of notifications, expressed as a bit mask. |
PRJ_NOTIFICATION_PARAMETERS Extra parameters for notifications. |
PRJ_PLACEHOLDER_INFO A buffer of metadata for the placeholder file or directory. |
PRJ_PLACEHOLDER_VERSION_INFO Information that uniquely identifies the contents of a placeholder file. |
PRJ_STARTVIRTUALIZING_OPTIONS Options to provide when starting a virtualization instance. |
PRJ_VIRTUALIZATION_INSTANCE_INFO Information about a virtualization instance. |
