What is a .SFCACHE file?

An .SFCACHE file is a type of cache file specifically used by the Windows Vista and Windows 7 operating systems. This file is typically created on a USB flash drive or other types of flash memory devices when you use a feature called ReadyBoost. ReadyBoost helps your computer perform better by using the storage space on a flash drive as additional memory. This extra memory acts like virtual RAM, which can speed up your computer, especially if your system is low on physical RAM.

To use ReadyBoost and create an .SFCACHE file, you need to plug a flash memory device into your computer. Then, follow these steps: 1. Right-click on the icon of the flash memory device in your computer. 2. Select "Properties" from the menu that appears. 3. In the Properties window, click on the "ReadyBoost" tab. 4. Check the option that says "Use this device." 5. Depending on your device's capacity, you can choose how much space to use for ReadyBoost.

Once you enable ReadyBoost, Windows will automatically create a file named "ReadyBoost.sfcache" on your flash drive. This file contains the cache used by Windows to store frequently accessed data, which can then be retrieved faster than from the hard drive.

The .SFCACHE file is primarily managed by the Windows operating system, and as such, it does not need to be opened manually. It is handled entirely by Windows when ReadyBoost is enabled. Therefore, there are no specific programs designed to open an .SFCACHE file other than the Windows operating system itself.
