What is a CACHE File?

How to Open, Edit, & Convert CACHE Files

A file with the CACHE file extension contains temporary information that a program sets aside because it assumes you'll want to use it again soon. Doing this allows the software to load the information faster than it would take to find the original data.

CACHE files aren't meant to be opened by anyone because the program that uses it, will use it when it needs to and then discard the CACHE files when necessary.

Some CACHE files can get pretty large in size depending on the program and data you're working with.

If your CACHE file is under a different format, it may instead be a Snacc-1.3 VDA file.

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

How To Open an CACHE File

Most CACHE files you encounter aren't meant to be opened by you. You can open one if you want to view it as a text document, but it likely won't help you read the file like you're used to with regular text-based formats like TXT, DOCX, etc. The program that created the CACHE file is the only software that can use it.

However, some CACHE files, like those used in Autodesk's Face Robot software (which is part of the discontinued Autodesk's Softimage), can be opened manually through the program. See this tutorial on Saving and Loading a Fast Playback Cache File to see how it's done.

Note: Since CACHE files are used by more programs than just Autodesk software, and for other unique purposes, you should check with the program you're using the CACHE file with, to see if it's possible to open one like you can with the Autodesk program.

To open a CACHE file to see it in its text form, just use a regular text editor like Windows Notepad or the free Notepad++.

Again, the text is most likely scrambled, so it probably won't serve any real purpose.

Tip: Since these text editors don't recognize the .CACHE file extension as a text document, you have to open the program first and then browse for the CACHE file. With Notepad++, you can just right-click or press and hold the CACHE file and pick Edit with Notepad++ from the menu.

Snacc-1.3 VDA files are associated with the Snacc (Sample Neufeld ASN.1 to C Compiler) program. I'm not sure if Snacc opens the CACHE file directly or if it just uses CACHE files in a similar way that I described above.

How To Convert a CACHE File

CACHE files aren't in a regular format like other files, so you can't convert CACHE to JPG, MP3, DOCX, PDF, MP4, etc. While those file types can be converted using a file converter tool, trying to use one on a CACHE file won't be of any help.

However, CACHE files that are 100% viewable in a text editor can of course be converted to another text-based format like HTM, RTF, TXT, etc. You can do this through the text editor itself.

If you have a CACHE file from a game built using Digital Extreme's Evolution Engine, the Evolution Engine Cache Extractor might be able to open it.

More Information on Cache Folders

Some programs may create a .CACHE folder.

Dropbox is one example - it creates a hidden .dropbox.cache folder after it's installed. It has nothing to do with .CACHE files. See What is the Dropbox cache folder? for details on what this folder is used for.

Some programs let you view the files cached by your web browser, but like I said above, the cached files probably don't use the .CACHE file extension. You can use a program like ChromeCacheView to see the files that Google Chrome has saved in its cache folder, or MZCacheView for Firefox.
