Palm Computing


Rated "5 Geekheads" for both Quality and Geekness by

Tap Magazine—Rated 9 out of 10—"Quick, easy to use and highly effective. A must-have utility for anyone bothered by duplicate database entries."

"I just received my registration # and within 1 minute of reading the email had eliminated over 500 duplicates from my Pilot databases. Rarely have I encountered a program that performed as simply and as well as UnDupe. When faced with the task of removing a large number of duplicates, the low price and easy purchase of your software make the decision a no-brainer.

Thank you for a wonderful product."

—Jeff Morgan

There are a variety of circumstances where through no fault of your own you'll find that all the entries in your Palm are duplicated, quadruplicated, or worse! We can't tell you exactly how or why it happens, but it happens. Instead of 500 entries in your Address Book, you'll have 1000, or 2000! If you ever try deleting them yourself, one by one, it's a nightmare. That's where UnDupe comes in. Just run the application, tap on the appropriate buttons, and the duplicates are removed! And it takes up only 14K on your Palm!

"This little gem saved my rear!"

—Michael Bee

Here's what the program looks like on your Palm:

As you can see it's pretty much self-explanatory. You can either delete duplicates from the Date Book, Address Book, Memo Pad, and To Do List (or Franklin Task List if you are using Franklin-Covey software) separately, or just tap on the All button and the program will delete duplicates from each of the four major applications. There's also a "Find Only" mode so you can have UnDupe tell you how many duplicates it finds in each database, without actually deleting them. You can do a fast search, which will catch most of the duplicates, or an "Exhaustive" search, which will find them all.

"This is the best software I've used all year! Thank
you for saving me hours of work. Your software rocks!

—Alex Sherman

UnDupe compares all aspects of the various items. For Date Book items, it compares date, start and end time, alarms, the item itself, and any attached note. For Address Book entries, it compares each of the different fields. For Memo Pad entries, it compares the entire memo, and for To Do list entries, it compares both the To Do item itself, the priority, due date, and any attached note. So items have to be exact duplicates in order to match (and then be removed). There are only three exceptions to the exact matching requirement. The first exception is "categories" - if UnDupe finds two entries, one of which is categorized and the other is "unfiled," it considers those duplicates and removes the one which is "unfiled" as you would expect (if they both are categorized in different categories, UnDupe considers them as two different entries and neither will be deleted). The second exception, which applies to the Date Book, Address Book, and To Do list, is with attached notes. If UnDupe finds two entries which are otherwise identical, and one has an attached note and the second does not, it will delete the one without the attached note (if they both have different notes attached, they are, of course, different and neither will be deleted). And third, UnDupe will ignore extra spaces and new lines ("returns") at the end of any text material, that is, "CA" and "CA " are treated as duplicates.

Note that there are some causes of duplicates which cause "near" duplicates. UnDupe will not find and remove duplicates of this nature.

PLEASE NOTE - UnDupe removes EXACT duplicates only. There can also be "apparent" duplicates which are not identical and which will not be detected and removed by UnDupe. We do not guarantee UnDupe will remove everything you think is a duplicate, and WE DO NOT OFFER REFUNDS BECAUSE UNDUPE DIDN'T REMOVE EVERYTHING YOU THOUGHT IT SHOULD. If you want to know how many duplicates UnDupe will remove from your Palm, please download the trial version before ordering the software and run it in the "Find" mode.

Want to learn more about UnDupe?

We've tried to keep this page simple, but the complete manual for UnDupe is part of the download when you download the software (see below). Even if you don't have a Palm, there are plenty of screen shots, so you can see everything the software can do, and how easy it is to use.

Want to try UnDupe yourself?

You can download UnDupe and put it through its paces without a Serial Number (password). The handheld software is fully functional without a serial number, but when you HotSync the data, only the first five items in any data you collect will be transferred to the desktop, and in addition, the software will expire in 14 days. This should allow you to fully evaluate what UnDupe can do for you and your business. Download now.
