- Filter driver to be tested, along with any supporting application suite
Hardware Requirements
- Computer that meets the minimum software requirements
- Windows keyboard
- Two-button pointing device
- Color display monitor capable of at least 1024 by 768 resolution, 32-bits per pixel, 60 Hz
- Hard drive with a minimum of 20 GB available on partition C:
- Extra hard drive space for four simple 2048 mb partitions and two simple 1024 mb partitions
Processor
The test tool runs on the following processor architectures:

- x64
Running the Test
Before running the test, the following partitions need to be added to the Windows environment:
| Label | File System | Size | Expected Drive Letter |
| NTFS | ntfs | 2048mb | g: |
| CNTFS | ntfs (compressed) | 2048mb | i: |
| FAT | Fat16 | 1024mb | k: |
| FAT32 | Fat32 | 1024mb | l: |
| ExFAT | ExFat | 2048mb | m: |
| UDF | UDF | 2048mb | n: |
When executed, the test will run variations for each of the six partitions above.
All test cases return PASS or FAIL. Review the test results in the log file for specific details about failures.
RunFileIO.cmd contains references to environment variables that can be changed to allow for skipping of certain file systems.
Command Syntax
| Command option | Description |
|---|---|
| rp_regres %DRIVE_ltr% | Specifies driver to test |
Troubleshooting
Note This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.
If you experience a test failure, run it with the option /V to have the test print additional information on variation failures. Example: rp_regres %DRIVE_ltr% /V
If you experience a large number of failures, make sure that you are running on the correct file-system type. You can also check the file-system information of a volume to make sure that Reparse Points are supported by using the following fsutil command, and looking for the output “Supports Reparse Points”: fsutil fsinfo volumeinfo %DRIVE_ltr%
