# akaiutil — AKAI Sampler Filesystem Tool

**Version 4.6.7** (21-OCT-2022) — GPLv2 — by Klaus Michael Indlekofer

Interactive console-based file manager for AKAI **S900/S950/S1000/S1100/S3000/CD3000** sampler disk images, floppies, hard drives, and CD-ROMs.

## Usage

```
akaiutil [-h] [-r] [-F] [-C] [-l <lock-file>] [-o <start-offset>] [-s <pseudo-disk-size>]
         [-n <pseudo-disk-number>] [-c <cdrom-index> ...] [-p <physdrive-index> ...]
         [[-f] <floppy-drive>] ... [[-f] <disk-file>] ...
```

### Options

| Flag | Description |
|------|-------------|
| `-h` | Print help |
| `-r` | Read-only mode (must come first) |
| `-F` | Disable floppy filesystem detection |
| `-C` | Disable block cache |
| `-l <file>` | Lock file for exclusive access |
| `-o <offset>` | Byte offset where disk data starts (decimal or `0x` hex) |
| `-s <size>` | Pseudo-disk size in KB (for multi-disk images) |
| `-n <num>` | Max pseudo-disks per file descriptor (max 8) |
| `-c <n>` | (Windows) Open CD-ROM `\\.\cdromN` |
| `-p <n>` | (Windows) Open physical drive `\\.\physicaldriveN` |

On Linux, pass raw devices like `/dev/da1`, `/dev/disk2s0`.

### Examples

```bash
# Open a floppy image
akaiutil fff.img

# Open harddisk images
akaiutil hhh1.img hhh2.img

# Multi-harddisk image with explicit size
akaiutil -s 524280 mmm.img

# Linux raw device access
akaiutil /dev/da1 hhh.img

# Read-only CD-ROM (macOS)
akaiutil -r /dev/disk2s0
```

## Virtual Filesystem

```
/disk<N>/<partition-letter>/<volume-name>/<file-name>
```

Shorthand: `/N` = `/diskN`, `/floppyN` = `/diskN/A/<volume1>`. Use `_` for spaces in names. `.` and `..` work as usual.
