More information about Personal Knowbase card file software
Migrate Your Old Cardfile Files to Personal Knowbase in 2 Easy Steps:
  1. When you first open Personal Knowbase, create a new, empty file by selecting the New command from the File menu.

  2. Import your Cardfile files using the Import command from the File menu. Select the Files of Type to be Card Files (*.crd), then browse to one of your files and Open it.

If you don't want to start playing with keywords yet, you can bypass the subsequent Keywords for Imported Files dialog box by clicking OK with no keywords.

This imports all the "cards" from your CRD file. Each "card" is referred to as an "article." Each card's title becomes the title of the Knowbase article, and each card's text portion becomes the content of the article. Note: This software can only import the text portion of CRD files. Any non-text (for example, graphical) portions of CRD files are not imported.

You can see a list of your titles in the main Index window. Just double-click on a title to open an article. Then you can tag each article with keywords to index them.

“Love your program. Have moved most of my datafiles, notes, and other assorted bits and pieces over to new Knowbase data files. It's so nice to be able to FIND things easily. I have recommended the program to many friends.”

“I just wanted to drop you a short note, telling you how much I believe your product "Personal Knowbase" rules. I've been trying it out for the past few days and without even getting close to the limit of the software's trial period, I decided to buy a license today... I've always had the feeling that I needed a tool to bring a little more order into my life. To give just a few examples: ... store all my passwords in a single place ... my movie collection ... serial numbers for software ... I'm sure that I'll find thousands of more things where Personal Knowbase will come in handy. Really, really great work you've done there!”
