Unzip files in psp

Could someone explain briefly how to use the application together with irshell that unzips .zip and .rar files

thx

...in irshell you press x on the zip/rar you want to unzip/unrar, it will take you to the app with everything you need filled in already and all you have to do in enter the password (if there is one) then click extract

cool me too i didnt know it

Does it come inside iR Shell or do you have to have it in the GAME folder?

well if you have irshell it automaticlly comes with it (in folder ms0:/irshell/extaapp/app4/)
if you want the eboot for game folder you have to download it in standalone format
