[BUG]: EXDEV: cross-device link not permitted

[TimPietrusky]

Describe the bug I have LoRAdo installed on drive D: on Windows. I leave all default configurations, uploaded 5 images, added captions and clicked on "prepare". Then it takes some time, nothing is happening in the UI besides the "loading" animation. In the CLI I see the following error instantly:

[Error: EXDEV: cross-device link not permitted, rename 'C:\Users\NERDDI~1\AppData\Local\Temp\34cc4814dea94a20066614202' -> 'D:\dev\js\failfast\LoRAdo\training\n3rdd1sc0\dataset\n3rdd1sc0--0003.jpg'] {
  errno: -4037,
  code: 'EXDEV',
  syscall: 'rename',
  path: 'C:\\Users\\NERDDI~1\\AppData\\Local\\Temp\\34cc4814dea94a20066614202',
  dest: 'D:\\dev\\js\\failfast\\LoRAdo\\training\\n3rdd1sc0\\dataset\\n3rdd1sc0--0003.jpg'
}

Then after some more time, the "loading"-animation on the "prepare"-button is gone and I get this error in the CLI:

ypeError: fetch failed

  }
}

The dataset is created, I also see the captions and the config.json. Just the images are not copied.

Expected behavior I can install LoRAdo on any drive I want and clicking on "prepare" will actually copy the images that I uploaded into the generated dataset.

Versions (please complete the following information):

• Browser: Chrome 115.0.5790.170 (Official Build) (arm64)
