Frequently Asked Questions
Why can't I open the file after I download a data set from ICPSR?
Data sets resulting from research studies like those found at ICPSR are usually compressed when downloaded. You must use a decompression utility like WinZip to "unzip" them before the actual file(s) can be opened. (Frequently one compressed file will contain several regular files.) See our
ICPSR downloading page for more information.
