Combine Multiple VCF Files Into One VCF File With 5 Methods

Why Merge VCF Files?

VCF files store contacts in the vCard format. RFC 6350 defines files with one contact or many contacts so one merged file imports in one step.

• One Import. Google Contacts asks you to select a file for every import so one merged file saves many repeats.
• Faster Backup. One file is faster to copy to an external disk or a cloud folder than 500 small files.
• Team Transfer. Sales and HR teams that move a contact list to a new CRM or email system send one file instead of hundreds.
• Clean Records. One file shows duplicate contacts and repeated names in a single place.

What to Check Before You Combine VCF Files?

Prepare four things before you merge.

• Copy the original VCF files into a backup folder because a merge cannot be undone with a command.
• Move the files you want to merge into a new folder with no other files.
• Open one file in Notepad and check the VERSION line. Version 2.1 or 3.0 or 4.0 shows there. Our guide to Open VCF File on Computer shows more ways to view a file.
• Count the contacts in the source files so you can compare the total with the merged file.

Which Free Methods Combine Multiple VCF Files Into One?

Four free methods use tools that you already have. Command Prompt and Terminal suit many files while Notepad suits a few files.

Command Prompt Copy Command (Free, Windows)

Microsoft states that the copy command joins every source file into one file when you enter a wildcard or a plus sign. Open the Microsoft copy command reference for every switch.

1. Create the folder C:\Contacts and copy all VCF files into it.
2. Click Start, type cmd and click Command Prompt.
3. Go to the folder with the command below.

cd /d C:\Contacts

4. Type the command below and press Enter.

copy /b *.vcf ..\merged.vcf

5. Count the contacts with the command below. Compare the number with the total of your source contacts.

find /c "BEGIN:VCARD" ..\merged.vcf

Microsoft does not state what happens when the new file matches the wildcard so the command saves merged.vcf in the parent folder C:\. Microsoft also states that copy treats combined files as ASCII files unless you add the /b switch. Switch /b copies the full content of every file including any end of file character (Ctrl+Z).

Find counts lines that contain BEGIN:VCARD. Fewer lines than expected mean two contacts joined on one line.

Terminal Cat Command (Free, Mac)

Mac and Linux join files with the cat command. Click Applications in Finder and open the Utilities folder. Click Terminal.

1. Move the VCF files into a folder named Contacts on your Desktop.
2. Type cd and the folder path.

cd ~/Desktop/Contacts

3. Type the command below and press Return.

cat *.vcf > ../merged.vcf

4. Count the contacts using grep.

grep -c "BEGIN:VCARD" ../merged.vcf

Saving merged.vcf in the parent folder stops cat from opening its own output file. Cat joins files in the order of their names and adds no line break either.

Notepad Copy and Paste (Free, for Few Files)

Notepad suits two or three files. Every extra file adds one more copy and paste and a wrong paste breaks a contact card.

1. Click the first VCF file with the right mouse button, select Open with and select Notepad.
2. Open the second VCF file in a new Notepad window the same way.
3. Press Ctrl+A and then Ctrl+C in the second window.
4. Click the last line of the first file and press Enter to start a new line. Press Ctrl+V to paste the contacts.
5. Repeat steps 2 to 4 for the other files.
6. Click File and select Save As. Select All files under Save as type, enter merged.vcf as the File name and select UTF-8 under Encoding. Click Save.

RFC 6350 states that vCard is UTF-8 so the encoding setting protects names with accents.

Google Contacts Import and Export (Free, Needs a Google Account)

Google Contacts imports VCF files into your account and exports the contacts as one vCard file. Google sets an account limit of 25,000 contacts and states that an import of more than 3,000 contacts can cause problems. Google lists the steps for a file in its Google Contacts import help.

1. Open Google Contacts in your browser and sign in.
2. Click Import in the left menu and click Select file.
3. Select the first VCF file and click Import.
4. Repeat steps 2 and 3 for every VCF file. Our guide to Import VCF to Google Contacts explains the import in detail.
5. Click Selection Actions and select All. Select only the imported contacts when the account has other contacts.
6. Click More actions and select Export.
7. Select vCard and click Export. Google saves the contacts in one VCF file.

   Outlook has no VCF option in the Export to a file wizard. Select contacts, click Forward Contact and select As a Business Card to save a separate VCF file per contact. Guides for Outlook 2013 also report that Outlook imports only the first contact from a VCF file with many contacts.

How to Merge VCF Files With EmailDoctor Software?

EmailDoctor vCard Merge Tool joins several VCF files in a single VCF file on Windows. Add single files or a full folder and the software merges them.

Free version adds files, previews contacts and selects a destination path. Merging needs the full version.

Six features matter for a merge.

• Add File or Add Folder. Select several VCF files at once or add a folder that contains them.
• Contact Preview. Click a file in the list to preview its contacts before the merge.
• Selective Merge. Tick only the files or contacts you want in the merged file.
• Output Version. Select v2.1 or v3.0 or v4.0 for the merged file under Advance Settings.
• Export Report. Save a report in CSV format after the export.
• Contact Details. Preserved fields include name, address, email, phone number, image and description.

Check the requirements before installation.

• Operating System. Windows 11, 10, 8.1, 8 or 7 and Windows Server 2008, 2012 R2, 2016 or 2019.
• Disk Space. 100 MB free.
• Memory. 1 GB RAM with 2 GB recommended.
• .NET Framework. Version 4.5 or newer must be present.

Merge VCF Files on Windows

1. Click the software in the Start menu with the right mouse button and select Run as Administrator. Click OK in the prerequisite window.
2. Click Add Folder in the top left corner.
3. Browse to the folder with your VCF files and click OK.
4. Wait while the software scans the folder.
5. Click OK when the scan finishes. Click a file in the list to preview its contacts.
6. Click Export in the top left corner.
7. Tick the box next to the folder name under Folder List to merge every file. Tick single files to merge only those. Select Merge vCard and click Advance Settings.
8. Select v2.1 or v3.0 or v4.0 as the version of the merged file.
9. Browse to a destination folder and click Export.
10. Click OK when the export completes.
11. Click Save to download the export report in CSV format.
12. Choose a folder for the report and click Save.
13. Open the CSV file to see the report. Import the merged VCF file into your contact application.

    Check the contact count of the merged file against your source files before you delete anything.

Which Method Suits Your VCF Files?

All five methods create one VCF file but they differ in platform and control.

Use Command Prompt or Terminal for a folder of files with the same vCard version. Use Notepad for two or three files and Google Contacts when you also want the contacts in your account. Merge software suits many files with mixed versions or a merge of selected contacts.

What Problems Appear When You Merge VCF Files?

Seven problems appear during a merge.

• Contacts Join on One Line. A source file without a final line break joins END:VCARD to the next BEGIN:VCARD. Add a line break at the end of that file in Notepad and merge again.
• Garbled Characters. Files with different encodings produce broken names. Save the merged file as UTF-8 in Notepad.
• Copy Command Stops Early. Without the /b switch copy treats combined files as ASCII files. Add /b to the command.
• Import Adds Only One Contact. Guides for Outlook 2013 report that Outlook imports only the first contact from a VCF file with many contacts. Use Google Contacts as the middle step.
• Duplicate Contacts. A merge copies every contact card so duplicates remain. Follow Delete Duplicate Contacts in Outlook to clean them in Outlook.
• Mixed vCard Versions. Some importers reject a file with versions 2.1 and 3.0 and 4.0. Select one version in the merge software before the export.
• Software Cannot Create Output. Source files must sit on the local disk and never on a NAS or SAN or a shared folder. Allow the software in your antivirus settings when the export is blocked.

Large merged files are easier to handle in parts. Our guide to Split a Single VCF File Into Multiple VCF Files explains the split.

Frequently Asked Questions

Final Words

VCF files can contain many contacts so joining their text creates one importable file. Duplicates and mixed vCard versions remain after a free merge.

Back up the originals and count the contacts before and after the merge. Import a small test file into your contact application first.

EmailDoctor software previews the contacts and sets the vCard version when you merge many files.
