What is win386.swp.

Additional information:

The Win386.swp is the Windows swap file used for Virtual Memory in the Windows environment. This allows the computer to provide more memory to applications than is physically present in the form of RAM.

This file can grow very large in size and needs space to grow. Hard disk drives with low available disk space will experience issues and decreased performance because of the lack of space available for this file to grow.

Additional information about swap files can also be found on our swap file dictionary definition.

Answers:

Below is a listing of questions and answers to those questions relating to the Windows Win386.swp file.

How can I change the Win386.swp file location?

It may be necessary and/or recommended that users with different partitions or hard disk drives store the win386.swp on a different hard disk drive. Reasons why this may be beneficial:

• If little or no space is available on the drive where win386.swp is located moving the swap file will help save space on that location.
• If a faster hard disk drive is installed onto the computer, moving the swap file location may help in increasing the performance of the computer.

How to move the swap file location in Windows 9x and Windows ME:

1. Click Start / Settings / Control Panel and double-click the System icon.
2. In System Properties click the performance tab.
3. Click the Virtual Memory button.
4. Select the option "Let me specify my own virtual memory settings."
5. Specify the hard disk drive where you wish for the win386.swp file to reside.

After setting custom virtual memory size, file changes from C:\<windows directory> to the root of C:\ drive.

This behavior is by design to help inform any individual examining the computer that a custom virtual memory setting has been selected.

After deleting the Win386.swp file it re-appears.

Windows Swap file is created by Windows and if it happens to be removed, Windows should recreate the file unless it has been disabled.

When storing the Win386.swp file on a removable media device and attempting to eject the storage medium from that device errors occur or the computer freezes.

Because the Windows Swap file is almost always being used, ejecting the device or removing the device storing this file will cause errors as it will remove the location of where information is temporarily being stored.

When booting from a removable media the performance tab may show that the computer is running in MS-DOS compatibility mode.

Change the location of the win386.swp file to a non-removable media.

Is the Win386.swp a computer virus?

While it is not impossible for a virus to be within the Win386.swp file it is very unlikely that you have a virus on the computer.

There are several users or so-called 'hackers' who claim that they have infected your computer with the Win386.swp virus. This file is not a virus but to some users it may appear to be a virus as the file grows very large in size as well as well re-appear after deleting the file.

If an individual has claimed to have sent you a virus through a chat channel, but you have not downloaded or accepted any files, it is very unlikely that you have a virus and that they are just trying to scare your or cause you to believe that they are a hacker.
