The PKG file is usually under 100 Megabytes because it only contains the XMB icon, background art, and a boot script.

It is an archive file that extracts directly into the PS3’s internal hard drive directory ( dev_hdd0/game/ ).

To help tailor this to your exact console setup, let me know: Are you running or PS3HEN ?

Some even joke that “wet” refers to – a “wet” (freshly pasted) PS3 runs cooler, making PKG installation safer. This is false but adds to the folklore.

| Feature | Dry (Folder / ISO) | Wet (PKG) | |---------|--------------------|------------| | Installation | Copy game folder (JB folder) or ISO to hdd0:/GAMES or PS3ISO | Install .pkg file via Package Manager | | Launch method | Multiman, webMAN, Irisman | Direct from XMB (like a PSN game) | | Space efficiency | Often requires disc backup space | Installs to internal HDD, can be larger | | Compatibility | Works with most games | Some games need conversion (e.g., pkg-merge ) | | Update ease | Manual patch installation | Can use official .pkg updates | | DLC support | Manual folder copying | Official DLC PKGs work seamlessly |

PKG files are compressed and often take up less space than their JB Folder or ISO counterparts. That means you can fit more games on your internal drive without sacrificing performance. For users with smaller hard drives (like the original 120 GB or 160 GB models), this efficiency can be a game‑changer.

The appeal of using a "wet ps3 pkg better" approach can be multifaceted:
