How to open a .vmem file
Start with a trusted app that supports this format
- Check the file extension carefully and confirm that the file name really ends with .vmem.
- Use software that supports this file type. If one app does not work, try another compatible program for the same platform.
- Update the application if the file was created by a newer version of the software.
- Scan files from unknown sources before opening them, especially documents, archives, scripts, installers, and executable files.
What is a .vmem file?
File extension details and usage information
The vmem file format is a proprietary data file used primarily by VMware virtualization software, such as VMware Workstation, VMware Player, and VMware ESXi. This file acts as a snapshot of the random access memory (RAM) of a virtual machine at a specific point in time. When a virtual machine is suspended or when a snapshot is taken, the contents of the guest operating system's volatile memory are written to the disk in the form of a .vmem file. This allows the virtual machine to be resumed exactly where it left off, preserving the state of all running applications, open documents, and the operating system kernel. Because these files contain a direct dump of the system memory, they can be quite large, often matching the amount of RAM allocated to the virtual machine. They are essential for features like 'suspend and resume' and for forensic analysis, as they can be examined to recover data or investigate system states that existed during the virtual machine's operation.

Can .vmem files be converted?
Options for saving or exporting this file to another format
In many cases, a .vmem file can be converted by opening it in compatible software and using an option such as Save As, Export, or Convert. The available output formats depend on the file type and the application used.
- Use the original software that created the file when possible.
- Check whether the application supports exporting to common formats.
- Be careful with online converters when working with private, business, or sensitive files.
- If conversion fails, the file may be corrupted, incomplete, encrypted, or not actually a .vmem file.
Why can't I open a .vmem file?
Common reasons this file type may not open correctly

Incorrect extension
The file extension may have been renamed manually, even though the actual file format is different.
Corrupted file
The file may be incomplete, damaged during download, or transferred incorrectly.
Outdated app
Your software may need to be updated before it can open newer versions of this file format.
Frequently Asked Questions
Common questions about .vmem files
To open a .vmem file, use software that supports this file format.
- VMware Workstation
- VMware Player
- VMware vSphere Client
- VMware Fusion
- VMware Workstation Player
Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.
- Verify that the file extension is correct.
- Install or update compatible software.
- Try another application that supports this format.
- Check whether the file is corrupted, incomplete, or encrypted.
A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.
File safety tips
Use caution with unknown files
Only open files from trusted sources. Before opening a .vmem file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
