I thought the "Extract + Delete" feature will not delete file if the extraction was unsuccessful (e.g wrong password). However, I found today if I try to unzip some of the 7z files, bandzip will delete the file anyway regradless of the result (e.g canceling the password prompt), sometimes it will not even prompt for password. Double click the file will ask for password and can view content successfully after input the password.
What I have found so far:
1. If the 7z file will ask for password upon double clicking (no file name will be seen without password), extract+delete will not ask for password, no file will be extracted and archive will be deleted.
2. If the 7z file will ask for password when trying to view the file content (file name will be seen without password), extract+delete will ask for password. But if you cancel the password prompt, no file will be extracted and archive will be deleted.
3. The 7z file I have is solid, I'm not sure if this is related.
4. It seems not related to filename of the archive file.
I'm using Bandizip 6.0 Beta 30. (64Bit)
