Theoretically, the maximum size of the database file can be up to 140 TB, but the developer has no hardware to test that. Although you probably may start experiencing some performance problems long before you reach this limit - say, if you collect close to ~100,000 records. However it should be large enough for any practical use.
There is no limit, you can create as many groups as you want. Group name is limited by 20 characters.
As many as your screen allows when the program window is maximized. But use common sense and display only the most important columns. The fewer the better: the table will otherwise look cluttered. Search looks for the data in all the columns, even in those that are not visible, so there is no need to view too many columns. You will see all the highlighted matches in the Contact Details.
If you have E-Z Contact Book database file from the versions 3.0 and newer (contacts.db), they can be imported (restored) directly from the database file (Database > Restore).
E-Z Contact Book database files from the versions 2.0 - 2.8 (contacts.fdb) have different format which is no longer supported.
No, groups can only be on one level. Having hierarchical group structure would unnecessary overcomplicate export/import functionality.
But there is an alternative way to group contacts together using tags. Please see Working with tags for more details.
No, a contact may only belong to one group.
But you can assign as many tags as you want to a contact, and use tags as alternative to groups. Please see Working with tags for more details.
The easiest way to backup data is to save database file (Database > Backup). The file name contains date stamp, so it is easy to find when the backup was made. And it is as easy to restore old data back, or load in another computer - see User Guide section on how to Restore database from backup files. Program automatically performs daily database backup by default, so you can use the most recent auto-backup file as a copy to transfer to another computer. But the best method to copy contacts from one computer to another and keep them up to date is to Sync using Google Contacts - that way eliminates several steps.
Yes you can, but not directly. Two methods of sharing contacts are available:
Use the option Copy to new contact, which is available in the right-click popup menu for a selected contact, or in the contact editor. It will create a new contact, copy all the Personal or Business data, except First and Last name. Group type (Personal or Business) the contact belongs to determines which (Personal or Business) data will be copied. The option is useful when you create multiple contact cards for members of a family, or group of employee of the same company. It was designed to reduce the amount of data entry.
The program by default is set to auto-format all phone numbers, so you don't have to enter any spaces or other punctuation when entering phone numbers - program does it for you. All you have to do is properly set up the format for your phone numbers. See more details on auto-formatting here. Some countries however have irregular formatting of the phone numbers, which is impossible to automate. If that is your case, turn auto-formatting OFF, and you will be able to enter phone numbers in the format you need.
That may only happen when you just installed the program but haven't created any contact group yet. At this point, the database is completely empty.
First step is to add at least one new group within the ALL CONTACTS heading, then you will be able to add any number of contacts. All contacts are organized in groups to make it easy to find them.
You may get the following error when trying to export data to Outlook - "Compatibility error exporting to Outlook ... Unable to find the WAB DLL": To fix this issue:
There is a known problem converting from Excel to a comma-delimited format, which is fortunately easy to fix. When you save an Excel spreadsheet to a comma-delimited file and then look at the phone number columns in the last one, you may notice that 12-digits (or longer) numbers look quite unreadable, in an exponential format, even if you make the column wider. For example, the number 112147483641 will look like 1.12147E+11. You can fix phone numbers as follows:
This may happen if your Gmail account is set to automatically add new contacts to the address book from emails.
Please check this link or this, they explain how to change your account setting to stop Gmail from adding contacts.
If you have used Sync with Google Contacts, you have a complete copy of all your contacts in your Google account. Just install E-Z Contact Book on a new or repaired computer. Then login to Google, and click Data > Sync with Google Contacts. It will reinstate all your contacts just in few seconds.
Notification options can be adjusted in Windows 10 for a specific application. To do that for E-Z Contact Book:
