Error in snaphu plugin export

I have been trying to unwrap my interferogram using SNAPHU-unwrapping plugin and getting the following error. After i run the “snaphu export”,it displaes 100% but there is nothing in my target folder. Anyone can help me? thanks.

please show the files in your export folder after unwrapping (with a screenshot)

Thanks for your reply.This is the process. In the process of snaphu unwrapping, after i click “Run”, nothing has happened, and there is no “UnwPhase.img” file generated in the target folder.

Looks like snaphu was not configured correctly. Please check the InSAR tutorials on a detailed description of the ok installation process: Sentinel-1 TOPS interferometry
