Split4G is a free, portable PC tool designed specifically to solve the >4GB file problem for PlayStation 3 users. It automatically detects and splits large files into 4GB chunks (usually 4,294,967,296 bytes) and, crucially, provides a method for the PS3 to recombine them on the fly using managers like multiMAN, webMAN MOD, or IRISMAN.
Unlike generic file splitters (e.g., WinRAR or 7-Zip), Split4G uses the .666XX naming convention (e.g., game.iso.66600, game.iso.66601, game.iso.66602), which is recognized natively by PS3 backup managers.
Key Feature: Split4G does not require installation. It runs directly as an executable on Windows (and reportedly via Wine on Linux/Mac).

Introduction: The PS3’s Inconvenient Truth
If you are a PlayStation 3 enthusiast who uses custom firmware (CFW), HEN, or even an official debug console, you have likely encountered the infamous 4GB file size limit. This isn’t a quirk of the console’s processing power—it is a limitation of the FAT32 file system. Split4G - PC Tool to split large -4GB - PS3 fil...
Most external USB drives come formatted as exFAT or NTFS, but the PS3 natively only reads FAT32 (or the proprietary, less stable NTFS via homebrew). FAT32 cannot handle a single file larger than 4GB minus 1 byte. Since many PS3 game backups (ISOs or JB folders) often contain .iso files or large .psarc archives exceeding 6GB, 10GB, or even 20GB, you cannot simply copy them to a USB drive.
Enter Split4G.
Split4G is a lightweight Windows utility that splits files larger than 4 GB into smaller parts so they can be moved to FAT32-formatted media (which has a 4 GB file-size limit). It’s commonly used for PS3 game backups, large video files, and other large data that must be stored on FAT32 drives (USB sticks, external HDDs formatted FAT32).
| Tool | Platform | Notes |
|------|----------|-------|
| PS3 ISO Tools | Windows | Splits + rebuilds PS3 ISOs specifically. |
| 7-Zip (store + split) | Cross-platform | Create .7z.001, .002 – less automatic. |
| multiMAN internal split | PS3 | Copies and splits from NTFS to internal. |
| Simple file splitter (e.g., HJ-Split) | Cross-platform | Requires manual merging on PS3 (not ideal). |
Split4G is a focused, no-nonsense answer to an old compatibility headache. It’s not flashy—just practical. If your workflow involves moving large files to devices stuck with the 4 GB ceiling, a small utility like this can save hours and a lot of frustration. Split4G is a free, portable PC tool designed

Split4G is a PC utility designed to bypass the 4GB file size limit of FAT32-formatted drives, allowing you to transfer large PS3 game files (like those found in God of War or Red Dead Redemption) to an external hard drive for use with your console. Guide to Using Split4G
Prepare Your Files: Ensure your game files (ISO, PKG, or folder format) are on your PC. If you are splitting a single ISO or PKG, place it inside a folder with the same name as the file. Open Split4G: Run the Split4G.exe application on your PC.
Select Source: Click on the source selection to browse for the game folder containing the large files.
Choose Destination: Select your FAT32-formatted external drive (or a temporary folder on your PC) as the destination. Key Feature: Split4G does not require installation
Set Split Format: Ensure the split format is set to "file name .666##" (e.g., .66600, .66601). This extension is critical for the PS3 to recognize the files.
Execute: Click Start or Execute. The program will identify files over 4GB and divide them into smaller segments. Rejoining Files on the PS3
Once you transfer the split files to your PS3, you must rejoin them to play:
The PlayStation 3 (PS3) uses the FAT32 file system for external USB drives by default. FAT32 has a critical limitation: maximum individual file size of 4GB. Many PS3 game backups (ISOs or folder-format games) contain files exceeding this limit (e.g., .psarc, .sdat, large movie files).
Split4G is a Windows-based PC tool designed to split such large files into 4GB chunks, allowing transfer to FAT32 drives for use with PS3 backup managers (e.g., multiMAN, IrisMAN).
Split4G splits large files into smaller chunks that fit under the 4 GB threshold. It’s optimized for the common FAT32/PS3 compatibility scenario: you feed it a file, it slices it into parts named sequentially, and those parts can be moved onto drives or devices that don’t accept single files larger than 4 GB.
