Not all of the supported file types are available from the
Windows Explorer right-click menu, as they depend on the other applications you
have installed on your computer. Alternative methods of opening a file for
deduplication are dragging the file from Windows Explorer onto the dedupeIT
window, or selecting File: Open in dedupeIT and then selecting the file.
Depending on your version of Windows, you may be able to select
Open With from the right-click menu and then choose dedupeIT. If dedupeIT is
not available from the Open With dialog, select Choose Program and then Browse
for the dedupeIT application.
The files listed depend on the file type that you select from the Files of type dropdown list:
If you still can't see your file after selecting the appropriate file type, select All Files to bring your file into view.
dedupeIT cannot process the file that you have selected. Check that it is a file containing your name and address data.
You have chosen an input file that has less than 40 records in
it (or it may not be a name and address data file at all). This file doesn't
have enough names and addresses in it for dedupeIT to make intelligent choices
about what the fields contain. dedupeIT will not work on files that are this
small, but they can be deduped easily by manual inspection.
Check that you have not got the file open in another application and that it is a file containing your name and address data.
