Notes about the QUAD 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 QUAD file type is primarily associated with 'QUAD' by Ilia Muraviev. QUAD is a high-performance file compressor that utilizes an advanced LZ-based compression algorithm. Its main features are high compression ratio and fast decompression speed.
