What is a ZIP-file?

Submit more examples

To add examples here send a copy of REC/CHK and QES files to info@epidata.dk
REC files can be without records. Just seeing the REC/CHK files without data from others can be very instructive.
Address and e-mail of provider contained in the zip files, only names and country here (antispam e-mail measure).

How to work with Example files in EpiData ?

  1. Download the ZIP-file containing the example to a temporary directory/folder (e.g. c:\windows\temp).
  2. Extract the files in the ZIP-file using an unzip/extractor program.
  3. Start EpIData and open the example file

ZIP files A ZIP-file is an archive containing one or more single files. Zip files take up less space and are therefore faster to send via internet. They are compressed in size. You must extract the single files in a ZIP-file archive using an extract-program, e.g. tools menu in EpiData
