Notes about the WA file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The WA file type is primarily associated with 'Waveform Archiver'. WavArc is another abandoned lossless compressor. It was developed up to 1997 by the Canadian programmer Dennis Lee.
