Hi Roman,
now i have found an very abnormal behavior.
The File "Adventurer 10 (1999)(Cyberpunks Unity)(Ru).trd" from the Sinclair ZX Spectrum Magazine Collection would be mention as match, but would not be automatically rebuilded. If this is done manually by zipping an copying, the scan process does not throw an error, so the file is correct. Is there a answer for this behavior?
