| ReadyBoost Cache Format | Microsoft | System Files |
The .sfcache file extension refers to storage files created and used by the Windows SuperFetch feature of the various Windows operating systems. This feature is part of the Windows Memory Manager ( WinMM.dll) library that was first introduced in Windows Vista and later versions like Windows 7, 8, and 10. Superfetch is responsible for preloading applications into memory for a faster system boot-up process and faster system response time.
SuperFetch caches applications and related data in specific file formats that are placed in the System Volume Information folder, which can be found under the root level of each drive. Data stored in the .sfcache format varies depending on the operating system version, but each file contains predictive information on applications used regularly, such as app initialization details, memory usage, startup times etc. Cached data is used to identify regular or frequently used programs, and optimizes them for faster launch times.
Usage with Other File Formats
AppStream ( .appx, appxbundle, msix, msixbundle, etc.), Setup Information Files ( .inf) and Feature Manifest ( .manifest) files are commonly used alongside the .sfcache file to optimize application startups and performance. As the cache files contain crucial information on application usage, they are necessary for restoring and operating applications smoothly on your system.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .SFCACHE) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .SFCACHE extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .SFCACHE file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .SFCACHE extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .SFCACHE extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .SFCACHE file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .SFCACHE file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .SFCACHE file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .SFCACHE file) will be extended to the maximum.
It is also good to check
- if the .SFCACHE file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
