## Background

Transactional NTFS (TxF) allows applications to perform file operations as atomic transactions. The $TxfLog directory contains transaction logs, and the $Tops:$T stream maintains transaction metadata. While TxF is deprecated in modern Windows versions, these files may still exist on systems and contain historical transaction data.

## Data Collected

This collector gathers structured data about $txflog $tops:$t.

## Collection Method

This collector uses kernel driver NTFS raw access to read $TxfLog $Tops:$T from each fixed NTFS drive.

## Forensic Value

TxF logs can provide evidence of transactional file operations and application activity. Although TxF is deprecated, these files may contain valuable historical data about file system transactions and can reveal application behavior patterns.
