BS5FileManager

BS5FileManager is a lightweight PS5 browser file-manager payload. It serves one web UI on port 5905, installs a small PS5 home-screen launcher tile, and lets the console perform large file operations locally instead of pushing everything through a slow remote copy path.

The project is intentionally scoped to file management only. It does not bundle patch payloads, game mounting logic, extra network daemons, forced cleanup tools, or companion service managers.

Runtime

Inject bs5filemanager.elf to your payload loader on port 9021, then open:

http://<PS5_IP>:5905/

On first run, the payload installs or updates a PS5 home-screen tile named BS5FileManager. The tile opens the local console URL:

http://127.0.0.1:5905/

When the launcher is newly installed or updated, the payload also asks the PS5 to open that local browser URL once. Later loads keep the tile available without forcing the browser open again.

Launcher state is stored in /data/BS5fm. The PS5 app tile itself still lives under /user/app/BS5F00001, which is the console app location used by the app install API.

The payload also shows a PS5 notification with the external browser URL when the web server is ready. Port 5905 is fixed so this payload can run next to older builds that may still be listening on another port.

Features

• Single browser file-manager UI
• PS5 home-screen web launcher tile
• Browse PS5 paths from the web UI
• Copy and move using PS5-side filesystem operations
• Recursive delete with progress and cancel
• Rename files and folders
• Create folders
• Upload files or folder trees from the browser
• Download one selected file through the browser
• Target shortcuts for /data/homebrew and /mnt/usb0
• USB shortcut discovery for /mnt/usb0 through /mnt/usb7
• Click-to-calculate recursive folder size
• Job progress with copied size, total size, speed, ETA, item counts, and current path

Folder sizes are calculated only when a folder is selected. Directory listings stay lightweight and do not recursively scan every visible folder.

Architecture

At a high level the payload has five parts:

• src/lite_main.c starts the payload, detects the LAN IP, sends startup notifications, installs the launcher tile if needed, and starts the HTTP server on port 5905.
• src/app_installer.c writes the embedded launcher metadata/icon under /user/app/BS5F00001, stores its update marker under /data/BS5fm, and registers the PS5 home-screen tile. The installer resolves the title-directory install function from libSceAppInstUtil.sprx at runtime and falls back to the broader app install call when needed.
• src/websrv_lite.c is a compact HTTP server. It serves the embedded UI, static downloads under /fs, and JSON APIs under /api/fs.
• src/transfer.c implements the file-manager API: list, stat, folder size, copy, move, delete, mkdir, rename, upload, job status, and cancel.
• assets/files.html is the complete web UI embedded into the ELF at build time by gen-asset-module.py.

Generated C files are written under gen/ during build and are ignored by Git. Built ELF files are also ignored; publish release binaries separately if needed.

Dependencies

Build requirements:

• ps5-payload-sdk
• GNU make
• Python 3
• LLVM/Clang toolchain compatible with the PS5 payload SDK
• A shell environment that can run the SDK build commands

Set PS5_PAYLOAD_SDK before building. If LLVM tools are not discoverable from your shell, set HOST_LLVM_BINDIR to the directory containing llvm-strip.

Build

export PS5_PAYLOAD_SDK=/path/to/ps5-payload-sdk
make clean
make

Output:

bs5filemanager.elf

Deploy helper:

make deploy PS5_HOST=<PS5_IP> PS5_PORT=9021

Safety Notes

BS5FileManager avoids forced process unloads and kernel-level cleanup. If an older payload is still running, this build does not interact with it; it uses port 5905 instead.

Recursive folder size, copy, move, and delete can still take time on very large external drives. Progress polling is tolerant of short hiccups, and active jobs continue on the PS5 side even if the browser temporarily loses contact. Copy, move, and delete jobs report PS5-side throughput in MB/s plus ETA from the server-side job counters.
