During the steps of processing that transform your Input Data Files into your Analysis Data Files, it may be convenient to temporarily save one or more files containing partially processed data, and then use the data from those files again at some later point in the processing. These files are called Intermediate Data Files.

Intermediate Data Files are created by commands you write in your processing scripts.

All of your Intermediate Data Files should be stored in the IntermediateData/ folder.

Naming Intermediate Data Files

Give your Intermediate Data Files short, simple names, such as



  •, cleanyear2,,

where .xxx represents the filename extension assigned to data files by the software you are using. (For example, if you are using Stata, .xxx would be replaced by .dta; if you are using R, .xxx would be replaced by .rda or .Rdata; and if you are using SPSS, .xxx would be replaced by .sav.)


Contents of the IntermediateData/ Folder


Any Intermediate Data Files created during the data processing required for your project should be saved in the IntermediateData/ folder.
