AppReadWriteCounter 1.45
A live monitor for application I/O activityAppReadWriteCounter is a portable Windows utility that monitors read and write activity by running processes. Its table shows operation counts and the total data read and written, with real-time updates to help identify applications generating I/O during troubleshooting. Users can export results to CSV or use command-line options in scripts. It is freeware from Nir Sofer.

AppReadWriteCounter for Windows 10 - Full description
AppReadWriteCounter is a portable Windows utility for examining the read and write activity of running applications. It is useful to developers, system administrators and advanced users who want to see which processes are accessing data, compare their activity or investigate possible I/O-related performance problems. Rather than requiring a full system-monitoring suite, it presents per-process counters in a compact table.
The main view lists active processes and reports their read and write operation counts alongside the total amount of data each process has read and written. These measures provide different kinds of context: operation counts show how often a process performs I/O, while byte totals indicate the overall volume. Other I/O activity is also represented. Users can compare entries to spot processes with unusually high activity, then observe the figures as they change during normal use or while reproducing a specific issue.
The display updates in real time, making it possible to follow changes without repeatedly restarting a scan. This can help narrow down which application is generating disk-related work during a slowdown, or show how a program's I/O changes after an action. The tabular layout keeps process names and counters together for quick inspection. Collected information can be exported to CSV for later review, record keeping or use in reporting workflows.
AppReadWriteCounter also supports command-line options, which can be useful when monitoring needs to be incorporated into scripts or repeatable diagnostic routines. It runs without installation, so it can be launched from a chosen folder or removable storage when troubleshooting different systems. Its small footprint makes it practical to keep available as a focused diagnostic tool rather than a continuously running monitor.
The utility is freeware from Nir Sofer and supports Windows 11, Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP, including 32-bit and 64-bit editions where applicable. It is intended for inspecting process I/O counters, not for controlling applications or changing their disk activity. Results are most useful when interpreted in context: high read or write totals can identify activity, but do not by themselves establish that a process is causing a performance problem.
