Opening SFCACHE files
Did your computer fail to open a SFCACHE file? We explain what SFCACHE files are and recommend software that we know can open or convert your SFCACHE files.
What is a SFCACHE file?
Files that contain the .sfcache file extension are created by the ReadyBoost feature that is included with the Windows Vista operating system.
Vista's ReadyBoost feature allows a user to plug a USB flash device into a USB port as a cache or virtual memory drive. This allows for faster caching and enhances the performance of a user's computer and reduces the problems that are commonly associated with limited computer memory.
The SFCACHE files are the cache files that are written to the added drive by the ReadyBoost application. SFCACHE files are active files, so they should not be disturbed when running on a system.
Software that will open, convert or fix SFCACHE files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
