What is PART file?

A .PART file is a partially downloaded Mozilla Firefox file. This way, files are saved in the process of downloading and those whose download has been stopped. .PART files may also be used by other applications to retrieve data. The file is downloaded linearly from start to finish. This means that a partially downloaded file can be opened, but it will be incomplete. Full file download is required for binaries. So all programs, project files, and archives must be downloaded.

How to open PART file?

The main problem with Partially Downloaded Format is that the PART file is incorrectly associated with programs. This causes the file PART to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the PART file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Mozilla Firefox

An often overlooked issue is to make sure that Mozilla Firefox is installed on the computer. To do this, enter the name Mozilla Firefox into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support PART files.

Step 2. Create association of Mozilla Firefox with PART files

However, it may happen that the application itself does not cause the PART file to open in the Mozilla Firefox application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Mozilla Firefox application as the default for handling the PART file.

Step 3. Update Mozilla Firefox to the latest version

If, however, after binding Mozilla Firefox with Partially Downloaded Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Mozilla website and install the latest version.

Step 4. Check for the following problems with the PART file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the PART file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the PART file that we want to open. As a result of the scan, sometimes it is not possible to recover PART files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the PART file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair PART file corruption. The easiest way is to restore the file from a backup, if there is one, or contact N/A
When reading, a message appears that the file was encrypted or corrupted. The encrypted PART files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move PART to a different directory.
This can happen on a file that does not support multiple access. In this case, the PART file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the PART file for a certain period of time. If this does not work either, restart the device.
