What is a CACHE file?
A .CACHE file is a temporary data file. Software programs create these files to store information for fast access. When a program needs the same data again, it reads the .CACHE file instead of downloading or processing the data twice. Many different programs use .CACHE files. For example, Mozilla Firefox and Google Chrome use them to store website images. Google Picasa uses them to store photo thumbnails. The Valve Source Engine uses them for game sound indexes.
How to open CACHE files?
Because the .CACHE extension is generic, you cannot always open it with a single program. The file content depends on the software that created it. Many .CACHE files are actually standard JPG, PNG, JSON, or ZIP files. If a .CACHE file is a renamed image, you can change the extension to .JPG or .PNG and open it with a standard image viewer. If it contains text data, you can inspect it using a text editor like Notepad++.
Inspecting unknown CACHE files
Because .CACHE has multiple possible meanings, it is difficult to know the exact format of your file just by looking at it. We recommend using viewer.online/cache to identify the actual format of the user's file. The platform analyzes .CACHE files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Converting CACHE files
If you identify the true format of your .CACHE file, you might want to convert it to a standard format for easier sharing. We recommend using convert.guru to handle file conversion. You can convert your .CACHE files to sensible target formats like JPG, PNG, or ZIP depending on the original content.
Summary
A .CACHE file stores temporary data to speed up software performance. Because .CACHE files use the known JPG format, viewer.online/cache can safely open and display them online, eliminating compatibility problems.
