Why does the space-time hunter uncompress the files forever?

This problem might have originated from the plot of some novels or games, but in reality, the reason why the file could not be fully unzipped did not exist. Uncompressing a file is usually achieved by compressing multiple files into a smaller file through a compression algorithm. The uncompressing process is to separate the files in the compressed file to obtain the required file size. This process is automatic and the size of the unzipped file will be reduced to a certain range of the original file size after the unzipping is complete. If there is an error in the extraction process or the extraction process cannot proceed smoothly due to other factors, the size of the extracted file may not be reduced to the expected range. However, in general, the size of the unzipped file would be automatically calculated according to the contents of the compressed file and the parameters of the compression algorithm. After the compression was completed, it would reach a reasonable size. Therefore, there was no such thing as the space-time hunter being unable to finish extracting the file. It was just a fictional plot in a novel.
