Description
===========

AppReadWriteCounter is a tool for Windows that counts and displays the
current file read/write operations of every application running on your
system. It displays the number of read/write bytes, the number of
read/write operations, current calculated read/write speed, and the
details about the application (product name, product version, and so on)
that makes the file read/write operations.



System Requirements
===================

This tool works on any version of Windows, starting from Windows XP and
up to Windows 11. Both 32-bit and 64-bit versions of Windows are
supported. On Windows Vista and later, if you want to view the full path
of system processes , you have to run AppReadWriteCounter as
Administrator.



Known Issues
============


* On Windows XP, for some applications (including AppReadWriteCounter
  itself) you may see constant increase in the read counters without any
  actual file read.

Start Using AppReadWriteCounter
===============================

AppReadWriteCounter doesn't require any installation process or
additional DLL files. In order to start using it, simply run the
executable file - AppReadWriteCounter.exe

Immediately after running it, the main window displays every application
that currently read or write files. Be aware that the counters in this
tool are not per process but per application, so if you have multiple
processes for the same application , AppReadWriteCounter merges them into
one line. Also, if you close an application and then run it again,
AppReadWriteCounter will continue the update the read/write counters of
the same application entry.
At any time, you can clear the entire list and start with empty window by
pressing Ctrl+X (Clear All). You can also reset the counters of selected
items by pressing Ctrl+R (Reset Selected Counters).



Command-Line Options

options (/stext, /stab, /scomma, and so on...)
The default is 10000 milliseconds (10 seconds).

/cfg <Filename>

example:
AppReadWriteCounter.exe /cfg "c:\config\arwc.cfg"

/sort <column>
This command-line option can be used with other save options for sorting
by the desired column. The <column> parameter can specify the column
index (0 for the first column, 1 for the second column, and so on) or the
name of the column, like "Application Namequot; and "Application Path".
You can specify the '~' prefix character (e.g: "~Write Bytes") if you
want to sort in descending order. You can put multiple /sort in the
command-line if you want to sort by multiple columns.





Translating AppReadWriteCounter to other languages
==================================================

In order to translate AppReadWriteCounter to other language, follow the
instructions below:
1. Run AppReadWriteCounter with /savelangfile parameter:
   AppReadWriteCounter.exe /savelangfile
   A file named AppReadWriteCounter_lng.ini will be created in the folder
   of AppReadWriteCounter utility.
2. Open the created language file in Notepad or in any other text
   editor.
3. Translate all string entries to the desired language. Optionally,
   you can also add your name and/or a link to your Web site.
   (TranslatorName and TranslatorURL values) If you add this information,
   it'll be used in the 'About' window.
4. After you finish the translation, Run AppReadWriteCounter, and all
   translated strings will be loaded from the language file.
   If you want to run AppReadWriteCounter without the translation, simply
   rename the language file, or move it to another folder.
