A very small change to find-file-in-file:
find-file-in-file.py contained containing 0x00000000 0x00000014 (50%) (End of containing file) Remaining 20 (50%)
When the tool reaches the end of the containing file, a message is printed to signal this: (End of containing file)
And I also added option -r (regular): to handle a ZIP file as a regular file.
