Chunker Remote — Split Large Files for Cloud Providers with Size Limits in RcloneView

Your video file is 15 GB. Your cloud provider's upload limit is 5 GB. Instead of re-encoding the video or finding another provider, the chunker remote splits it automatically.

Some cloud storage providers impose maximum file size limits. Google Drive caps at 5 TB (rarely an issue), but other providers — especially free tiers, WebDAV endpoints, and some S3-compatible services — have much lower limits. Rclone's chunker remote solves this by transparently splitting large files into chunks for upload and reassembling them on download.

How Chunker Works

A chunker remote wraps another remote and:

  1. Splits files above a configurable size into numbered chunks
  2. Uploads chunks individually to the cloud provider
  3. On download, reassembles chunks into the original file
  4. Transparently — you see the original file in the explorer, not the chunks

For example, a 15 GB file with a 5 GB chunk size becomes three 5 GB chunks on the provider. When you browse or download, it appears as a single 15 GB file.

When You Need Chunker

ScenarioSolution
Provider has file size limitChunker splits above the limit
WebDAV server rejects large uploadsChunk into smaller pieces
Free tier with per-file limitsSplit to fit within limits
Network drops on large uploadsSmaller chunks = easier retries

Set Up a Chunker Remote

Create chunker remote

Create a chunker remote that wraps your target storage remote. Configure the chunk size based on your provider's limits.

Combine with Other Remotes

Chunker can be layered with other special remotes:

  • Chunker + Crypt: Split AND encrypt large files
  • Chunker + Compress: Split AND compress large files
  • Chunker + any provider: Works with all 70+ providers

Important Notes

  • Chunks are provider-specific: files chunked for one provider must be accessed through the same chunker configuration
  • Don't modify chunks directly: always access through the chunker remote to maintain integrity
  • Choose chunk size wisely: too small creates many files (slower listing); too large defeats the purpose

Use Cases

Back up VM images

Virtual machine disk images are often 50-200 GB. Chunker splits them for providers with upload limits.

Archive large media files

4K video files, raw audio masters, and large datasets that exceed single-file limits.

Improve upload reliability

Smaller chunks are easier to retry when network connections are unreliable. If a 1 GB chunk fails, you retry 1 GB instead of the entire 50 GB file.

Getting Started

  1. Download RcloneView from rcloneview.com.
  2. Add your storage remote normally.
  3. Create a chunker remote wrapping it.
  4. Upload large files through the chunker.

No file too large, no provider limit too small.
