Hello, i want to issue a pkunzip extract with a password on a zip file and extract it to a directory which will be deleted when finnsied with (i.e tmp dir). The zip files I have are on cd, and i have made a autorun menu to issue a command when the icon for say a program is pressed. The program is a zip file with a password and in there is usually a Setup.exe file. At first i wanted to run Pkunzip or an unzip program that would run the setup file and install itself without having to extract itself to the hard drive, but too many people are saying it is not possible. The reason i want to do this is because the zip file is password protected and i do not want them to use the menu program (which issues the password secretly) and capture the files in the extract dir and save them for their own use and to duplicate. Any sort of help would be helpful or any ideas on other programs that could do the job other than ZIP programs also would be great.
