Which file formats should I use when depositing data in the MRU Data Repository?


The repository supports most file formats, but when possible, datasets should be saved in formats that support long-term preservation. These are often non-proprietary, open formats.

Examples vary by data type. For tabular data, some CSV, Excel, R, SPSS, and Stata formats can be ingested, and tabular files may be converted to a preservation-friendly tab-separated format during ingest.

Other file considerations:

  • individual files and compressed folders can be up to 5 GB in size
  • multiple files may be included in a dataset
  • files should be named clearly and consistently
  • avoid spaces and special characters in file names
  • multiple files may be organized into hierarchical folders
