I updated one file inside a ZIP using the 7Z update command. But BC 4.0.1 19165 showed the ZIP file as identical to a backup copy of the original, and showed the updated file with its original modified date in both files. After I opened the 'identical' updated file in a BC file comparison, it showed the correct dates and a difference between the old and new files (they were the same size). And now the second ZIP has been updated in other places, and opening the ZIPs in a new copy shows the date correctly for the original updated file.
In the original problem state, I tried opening the new ZIP in Winzip, 7Z and WinRAR, and all showed the updated file with its correct date and new content. But comparing the ZIP with itself in BC showed the old date of the updated file. The file is in a folder in the ZIP.
