The Change Journal provides a new level of detailed information for applications that need to monitor changes on an NTFS volume.
The Change Journal can also reduce the need for applications to walk the entire hard drive full rescans. Many utilities rely on full rescans to occasionally gather up-to-date information.
Now an application can do a full rescan just once and then rely on the Change Journal to tell it exactly what files or directories have changed and when. The system hides this file so that you cannot view it using familiar tools like the Explorer and the CMD shell. Whenever the file system makes a change to a file or Asus K42JZ Notebook Azurewave WLAN, it appends a record to the journal.
The record identifies the file name, the time of the change, and what type of change occurred. The actual data that changed is not kept in the journal, so don t get your hopes up about being able to roll back changes this keeps the size of the journal as small as possible. The Change Journal is initially an empty Asus K42JZ Notebook Azurewave WLAN on the disk volume.
As changes occur to the volume, records are appended to the end of this file. That s why the structures and defines in the winioctl. When a record is added to the journal, it is assigned a USN. The Change Journal always writes new records to the end of the file, so the implementors chose to use the file offset of a record as its USN. This makes querying the journal fast since the system can simply Asus K42JZ Notebook Azurewave WLAN the desired record using the USN.

Since records include a file name they vary in length, so you ll notice varying Asus K42JZ Notebook Azurewave WLAN between USNs of adjacent records. A typical record might be bytes long. The system will not allow a single record to span the boundaries of a page, so you ll sometimes see a gap in USNs where empty space was used to pad the end of a block.
Each record in the MFT describes a file or directory s name, location, size, attributes, and more. With NTFS 5.
This is also true for directories. In our next article, we ll show how this information is useful with a technique that can quickly scan the MFT for all files that changed over a range of time.
If the Asus K42JZ Notebook Azurewave WLAN file gets too big as defined by the MaximumSize parameter, the system will purge the oldest records at the start of the file. The end of the file must be copied to a new location, which is a time-consuming task. Fortunately, NTFS 5. The Change Journal is a sparse file, allowing the purging of records without any performance penalty.

In addition, remaining records can still be quickly located using the USN since they remain at the same logical offset. For more information on sparse files see the article A File System for the 21st Century: Previewing the Windows NT 5.
A Change Journal can be disabled on a given volume, preventing the system from logging file and directory changes. Some application must explicitly activate the journal. Also note that any application can activate or disable the volume s journal at any time. An application must be able to gracefully handle the situation when a journal is disabled while the first application is still using the journal.

We ll describe Asus K42JZ Notebook Azurewave WLAN applications can handle this in a future article. When an application disables the Change Journal for a volume, the system will also purge any existing records to prevent recovery of the information.
