Notes about the SMR 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 SMR file type is primarily associated with 'Spike2' by Cambridge Electronic Design. Waveform and time stamp data capture and analaysis. The data for each channel in a .SMR file is held in a list of blocks. Each block holds a pointer to the next block and the previous block on disk.
