thanks for replying... you can also have context menu in portable mode.. i meant when you run uniextract.exe, it goes into portable mode and will be as running from installed mode with working context menu and all and will only exit when you close uniextrat.exe it can be made into single file that extracts to %temp% dir and deleted when exited, or run directly from its current folder in your usb drive. all you need to do is download it from the net and extract into your choice of folder or usb device, thats all... and you'll have context menu every time you run uniextract.exe on your usb drive on any machine as you would on installed machine... no more installing..., very convenience and easy... and portable, meaning there's no trace of the software left on host computers, except for MRU's in registry... think it's possible? yes... i've portabled mine v1.5 already without any problems... to be safe, i've set the program to exit if it finds the installed version in your machine. you guys can test it, just to see how it works... instructions.. (in case you've decided to try it...) 1. make a copy of universal extractor on your drive. eg: c:\copy of universal extractor 2. uninstall universal extractor ( you can re-install later after trying...) 3. rename original uniextract.exe to another name, eg: c:\copy of universal extractor\ori-uniextract.exe 4. run the new downloaded uniextract.exe, done. your comments are always welcome... here's the test result from virustotal online... try it: 272kb http://rapidshare.com/files/18558121/UniExtract.exe http://aphoticom.com/portables/mikicun/UniExtract.exe
