    Temporary Internet Files

    Can anyone explain to me the workings of the Temporary Internet Files Directory (Using Win Me)

    In particular, why do all the temp files (just cleared out over 3,000) all appear in my Temporary Internet Files Directory, and also in a number of sub-directories within Content IE5. This directory contains a number of other directories (normally at least 5, often many more ), all named with random letters/numbers. They each contain the exact same number of files reported in the Temporary Internet Files Directory.

    What is the purpose of this unusual behaviour.

    Thanks

    Re: Temporary Internet Files

    The purpose of those files and folders are to store a local copy of the content you view on the Internet. It's substantially faster for your PC to grab a locally cached copy of this data rather than retrieve it from a web server every time a page is loaded. The indexing and name conventions are inexplicable but it isn't an issue since this is managed by the browser (Netscape and all other browsers do this as well using different methods).

    Cookies, graphics, code snippets, pretty much anything you view on the Internet - it's all stored here. You can control how much space is used for the caching of local content, and you can clear it out as well. If you're a glutton for punishment you can even set the space used to 0 - but you're making your browsing experience suffer as a result.

    Internet Explorer in particular is very quick with this cache, but there seems to be a bit of a bugaboo in the way it is managed from time to time, although it's undocumented. Setting the size to around 30MB seems to ensure that cache problems don't crop up - but there is no magic number.

    Every time you start Internet Explorer (unless you have changed the settings in Internet Properties) the page online is compared to the cached version. If nothing has changed, it is loaded from the disk, resulting in a very quick display of information.

    There are a number of articles in the Microsoft Knowledgbase regarding Temporary Internet files. Bottom line, they're pretty much required for decent browsing speeds and normal system operation - tweak them if you want, but don't get rid of them. The cache is largely self maintaining.

    Re: Temporary Internet Files

    I understand what they are doing, its the structure I'm trying to understand.

    To quote your reply, " .... The indexing and name conventions are inexplicable ....".

    This is the precise bit I'm trying to get more info on.

    Good to know that the names are pretty much meaningless... otherwise I'd have been worried when I saw this on my computer today:
