GEDmatch is a powerful platform for genetic genealogy, allowing users to compare DNA kits and explore family connections beyond what standard testing services offer. One of the most frequently used features on GEDmatch is the match list, which provides a detailed record of potential relatives, shared centimorgans, and segment information. For many users, this list is essential for tracing family history, confirming relationships, and conducting research.
However, there are instances when the GEDmatch match list may disappear from a computer. This can be alarming, especially for users who rely on the information for ongoing research. The disappearance of the match list does not necessarily mean the data is lost permanently. With the right approach, most users can recover their match lists and restore access to their valuable research.
This guide explores the possible reasons why match lists disappear from computers and provides step-by-step solutions to recover them.
Understanding the GEDmatch Match List
The GEDmatch match list is generated when you use tools such as One-to-Many DNA comparison. It includes a comprehensive display of potential matches along with crucial details such as kit numbers, names (if provided), total shared centimorgans, largest segment shared, and predicted relationships.
Because the match list can contain hundreds or even thousands of matches, many users download it as a CSV or save it as a file on their computer. This allows for offline analysis, record-keeping, and sharing with family members or genealogical collaborators. Losing access to this list can disrupt research and cause concern about data loss.
Common Causes of Disappearing Match Lists
There are several reasons why a GEDmatch match list may disappear from a computer:
File Deletion: The file may have been accidentally deleted or moved to a different folder.
Browser or Cache Issues: If the list was not saved properly or was stored in a temporary browser cache, clearing the cache may make it inaccessible.
Software Updates: Operating system or browser updates can sometimes affect saved files or change default download directories.
Data Corruption: Files can become corrupted due to power interruptions, improper shutdowns, or malware infections.
Download Errors: Partial downloads or network interruptions can result in incomplete or missing files.
Understanding the cause of the disappearance is essential for determining the correct recovery approach.
Check Your Computer’s Recycle Bin or Trash
The first step in recovering a lost match list is to check your computer’s Recycle Bin or Trash folder. Files that are accidentally deleted often remain in these folders until they are permanently erased.
Open the Recycle Bin or Trash, search for the match list by name or file type (such as CSV), and restore it if found. This is usually the quickest and simplest way to recover a lost file.
Search the Entire Computer for the File
If the file is not in the Recycle Bin, the next step is to perform a comprehensive search of your computer. Use the search function in your operating system to look for the file by name, file type, or approximate date of download.
On Windows, the search bar in File Explorer allows you to filter by date modified, file size, or file type. On Mac, Spotlight can help locate files across all directories. This method is particularly useful if the file was moved accidentally to a different folder.
Check Default Download Locations
If the match list was downloaded from GEDmatch, it is possible that it resides in the default download folder of your web browser.
Open your browser’s download history to locate recent files. Common default folders include “Downloads” or “Documents.” If you locate the file, move it to a secure location to prevent future loss.
Recover From Cloud Backup Services
Many users automatically sync their computers with cloud storage services such as OneDrive, Google Drive, or iCloud. If the match list was stored in a synced folder, it may still be available in the cloud even if it disappeared from your local computer.
Log into your cloud storage account and check for the file. Some services also maintain a trash or deleted files folder where you can restore recently deleted items.
Use File Recovery Software
If the file cannot be located through normal search methods or cloud backups, file recovery software may help. These programs scan your storage drives for deleted or corrupted files that are still recoverable.
Popular file recovery tools can restore CSV or text files, even if they were removed from the Recycle Bin. It is important to minimize use of the computer’s storage after deletion to prevent overwriting the file, which can reduce the likelihood of successful recovery.
Re-Download the Match List From GEDmatch
If the original match list was lost but your DNA kit remains active on GEDmatch, you can regenerate and re-download the list.
Log into your GEDmatch account, access the One-to-Many tool, and run the comparison for the relevant kit. Once the results are displayed, save the match list again in a secure location on your computer or cloud storage.
This approach ensures you have a fresh copy of the match list, reducing dependency on previously downloaded files.
Maintain Multiple Copies
To prevent future data loss, consider maintaining multiple copies of your match lists. Save one copy on your computer, another on an external hard drive, and optionally a third copy in cloud storage.
Regular backups protect against accidental deletions, hardware failures, or software issues, ensuring that your research remains intact.
Ensure Proper File Naming and Organization
A common reason files appear to disappear is poor organization. Use clear and consistent file naming conventions when saving GEDmatch match lists. Include the kit number and date to make it easier to locate files in the future.
Organize files into folders by kit, project, or year. A structured approach reduces the risk of accidental deletion or confusion when multiple match lists are downloaded.
Avoid Relying Solely on Browser Cache
Some users temporarily view or save match lists from browser cache without downloading them properly. While this may work for short-term viewing, cache files are cleared when the browser is closed, updated, or cleaned.
Always download and save match lists as permanent files to prevent loss. Using a dedicated folder for GEDmatch exports can simplify file management.
Monitor System Updates and Antivirus Programs
Occasionally, operating system updates, antivirus scans, or security programs can quarantine or remove files if they are flagged as unusual.
Check your antivirus program’s quarantine folder for the missing match list and restore it if appropriate. Similarly, be aware of recent system updates that may have affected file locations or default directories.
Final Thoughts
The GEDmatch Match List Missing From Computer can be stressful, especially when it contains crucial data for genealogical research. However, in most cases, the list is not permanently lost. By carefully checking the Recycle Bin, performing system searches, accessing cloud backups, using file recovery software, or re-downloading from GEDmatch, you can restore your match list efficiently. Developing strong file management practices, maintaining multiple backups, and organizing files properly will help prevent similar issues in the future. With these strategies, you can ensure that your GEDmatch research remains secure and accessible for ongoing exploration of your family history.
