You need about four times as much work file space on your disk as the size of your data file, but only two times as much space as the size of your data file if you include the control instruction PRCOMP=No. You need this space on the disk of your temporary directory. This is usually the Windows temporary directory. Double-click "My Computer" and right-click on the disk drive. The "properties" shows the amount of available disk space. You can choose your own temporary directory, see WINSTEPS.INI .

The Table report files are placed temporarily in the current directory (reported on your screen when WINSTEPS starts). Delete unwanted files to give yourself more disk space, or log onto a different disk drive, with more available space, before executing WINSTEPS. Files with names "Z......ws.txt", "Z......ws.xls", "(numbers)ws.txt" and ".TMP" and files in your temporary directory are work files. These can be deleted.
