File size and number of files

When uploading data to the BSC Dataverse, please be aware of the following restrictions:

  • Maximum file size: 2.5 GB per file.
  • Maximum number of files per upload: 1000 files.

If your dataset exceeds these limits, we recommend splitting large files into smaller, more manageable parts, compressing multiple files into a single archive (e.g., .zip, .tar.gz), or contacting the BSC Data Management team for further assistance.

💡 When you upload a .zip file, it will be automatically extracted. This means:
  • All individual files within the .zip will be visible in Dataverse.
  • The original folder structure will be preserved.
  • You only need to upload a single file—no manual extraction required.

For larger files, we recommend splitting and compressing them before uploading.

Mac/Linux: Split and archive a large file To compress and split a file into 2GB parts, use the following command:

tar -czf - largefile | split -b 2000M - largefile_part_
⚠️ Once the files are uploaded, it takes a while (10s - 40s) for Dataverse to show the new files.
