FileActivityWatch is a tool for Windows that displays information about every read/write/delete operation of files occurs on your system.
For every file, FileActivityWatch displays the number of read/write bytes, number of read/write/delete operations, first and last read/write timestamp, and the name/ID of the process
responsible for the file operation.
This tool works on any version of Windows, starting from Windows Vista and up to Windows 10. Both 32-bit and 64-bit systems are supported.
Elevation ('Run As Administrator') is required to use this tool.
