How to open QCOW2 file?
The main problem with QEMU Copy-On-Write is that the QCOW2 file is incorrectly associated with programs. This is manifested by the fact that QCOW2 files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the QCOW2 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 Qemu Manager
In this case, you should first verify that the Qemu Manager application is installed on the computer. The easiest method is to use the system search engine by entering the program name Qemu Manager in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open QCOW2 files.
Programs to open QCOW2 file
Remember to download programs supporting QCOW2 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Qemu Manager with QCOW2 files
If the application is or has been freshly installed, but the QCOW2 file still does not use the Qemu Manager program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Qemu Manager application as the default for handling the QCOW2 file.
Step 3. Update Qemu Manager to the latest version
The fault may also lie with the Qemu Manager program, it is possible that QEMU Copy-On-Write requires a newer version of the program. In this case, use the David T Reynolds website or update the program from the application.
Step 4. Check for the following problems with the QCOW2 file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the QCOW2 file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the QCOW2 file that we want to open. Sometimes virus-infected QCOW2 files cannot be recovered, so make a backup in advance.
Older version of QCOW2 file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular QCOW2 file corruption. You can restore the file from a backup or use David T Reynolds help.
The program can also signal the fact of encryption. The encrypted file QCOW2 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the QCOW2 file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the QCOW2 file again. Some anti-virus or backup software may occupy the QCOW2 file for a certain period of time. If nothing helps, please reset the device.
