Non Mac OS Users

For non Mac OS users, it is recommended by the ADA that all CSV, Stata, SPSS, SAS and Excel file formats be double-zipped using the 7-Zip open source software. This software is also used by the ADA Staff and is free. This ensures that the files and folders remain unaltered during the Dataverse upload process and prevents Dataverse from adding functionality that the ADA do not utilise at the current time and are currently unable to support. Copies of the software can be obtained via the links at https://www.7-zip.org/.

Double-Zipping Guidance Notes using 7-Zip

1. Right click on the file to be encrypted and select “7-Zip” and then the “Add to archive…” option. 

2. In the Add to Archive window, change the name of the archive that you wish to create if the name differs from the file name selected. Remember that file names need to conform to ADA standard naming conventions.

3. Change the Archive format to “Zip”.  

4. Files and folders do not require encryption therefore you do not need to select a preferred encryption method or enter a password. Simply select “OK” to create the archive file. This file will be located in the same folder or area as the original file. 

5. To Double-zip the file (or folder), repeat steps 1 thru 4 above but this time selecting the zipped file or folder. If you fail to Double-Zip the files or folders the original formatting may be altered during the ingest process by Dataverse and the unwanted Two Ravens explorer function will be added.

If you do not wish not to use the 7-Zip product you should contact ADA Staff to discuss the implications of using an alternative software package prior to uploading your files (and folders).
