What is a CACHE File?

Question: What is a CACHE File?

Did you find a CACHE file on your computer and wonder what program should open it? Maybe someone emailed you a CACHE file but you're not sure how to use it. Perhaps you tried to open the CACHE file but Windows told you that it could not open it.

Before you can open a CACHE file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .CACHE file extension refers to.

Answer: A file with the CACHE file extension is usually a temporarily create file, not intended to be opened or used directly by a human being.

Some CACHE files are Snacc-1.3 VDA files.

If you're trying to figure out how to clear cached files created by your web browser, which rarely has anything to do with files that end in the CACHE extension, see How Do I Clear My Browser's Cache? for help.

Other types of files may also use the CACHE file extension. If you know of any additional file formats that use the .CACHE extension, please let me know so I can update this information.

How To Open an CACHE File:

The easiest way to open a CACHE file is to double-click on it and let your PC decide which default application should open the file. If no program opens the CACHE file then you probably don't have an application installed that can view and/or edit CACHE files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

CACHE files can usually be opened with a regular text editor like Windows Notepad. The data may seem scrambled because CACHE files are normally associated with temporary files created by programs, and not intended to be opened.

Tip: Use Notepad or another text editor to open the CACHE file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with CACHE files but it's worth a try.

If you find that an application on your PC does try to open the CACHE file but it's the wrong application or if you would rather have another installed program open CACHE files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert a CACHE File:

There are two main ways to attempt to convert a CACHE file to another file type:

The first option involving opening the CACHE file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens CACHE files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the CACHE file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
