Depending on the size of your array, the combined size of these files may exceed several gigabytes, even after they are compressed into the ZIP archive format required for uploading to caArray. Since the maximum size of a ZIP file that can be uploaded is 2 GB, any dataset which exceeds this size limit must be broken down into smaller chunks, each of which contains a subset of the original data.

1. Divide the array data files into smaller batches, each of which will be no larger than 2 GB following ZIP compression.
2. Split the original SDRF file into multiple SDRF files, each corresponding to a single batch and referencing only the array data files from that batch.
3. Create multiple IDF files derived from the original IDF, with each one uniquely referencing one of the SDRF files created in the previous step.
4. Create multiple ZIP archives, each a ZIP archive for each batch, containing a single IDF and its associated SDRF and raw and array data files.
5. Upload each ZIP archive individually, then validate and import the files from each.
