Agelong Tree is a program for building family trees, for storing and displaying information about people and events in their lives, for storing texts, photos, audios and videos connected to them. A user enters information about relatives, and Agelong Tree builds family trees or lineage lists for any chosen person. Go to page About Agelong Tree to see a brief list of program features.

Agelong Tree stores data only on the user's computer, no data are sent to the Internet. Data are placed in a *.at5 file. Photos and other documents originals are placed in a documents folder, it has the same name as the data file plus “.files”. When it is necessary to replace the data file, the documents folder must be replaced too.

Family tree data are precious. Agelong Tree automatically suggests creating an archived backup copy to prevent data loss. Once you have created an archived copy of data, Agelong Tree counts a certain number of data modifications and then suggets creating a new copy of data. The backup zip archive contains a data file and a documents folder with all documents, photos etc. We strongly recommend to save the archive on an external disc or in a cloud storage, it will help to restore data in case of computer breakdown.
