mmf is a music folder, and it is in the C drive. It is a system file, so do not delete it.

Which files in the c drive can be deleted:

Although the Windows XP (hereinafter referred to as XP) system occupies a large amount of hard disk space, many files are not necessary for normal operation of the system, and Not every user needs it, so we can manually "slim down" the system without using any software. Firstly, it can save hard disk space, and secondly, it can improve the running speed of the system.

Clean the Documents and Settings directory?. "Documents and Settings" is a special directory in XP, which records some special file information of the user.

Let’s take a look at what content can be deleted. C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\Default Pictures ? Used when setting up an account or using MSN. There is nothing special about these pictures, you can delete them or replace them with your favorite pictures. C:\Documents and Settings\Username\My Documents\My Music ? Generally, people open a special place on the hard disk to store music, so delete it. One thing to note: If you often play WMA files, you will inevitably download some music playback licenses to the local hard disk, and the system will place these licenses in this directory by default. If you see the "License Backup" directory in the directory, It is recommended to copy it to another location and change the path in "Tools/License Management" of WMP. C:\Documents and Settings\Username\[Start] Menu\Programs\Accessories ?This directory is the shortcut icon for some programs. There are very few functions that are actually used in the attachments. The only commonly used functions are "Notepad" and "Windows Explorer". Copy the required program shortcut icons to "C:\Documents and Settings\All Users\[Start] Menu\Programs\Accessories", and then delete this directory. ?

C:\Documents and Settings\Username\Favorites ?Delete the shortcut icons here, "MSN.com" and "Radio Station Guide" if they are no longer useful. ?

C:\Documents and Settings\Username\Favorites\Links ?Same as above, if you no longer need it, you can delete this directory. Here you also need to modify the registry to permanently delete the linked folder. Find the "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Toolbar" key in the registry and delete the value of "LinksFolderName" on the right. ?Purpose: To streamline the directory structure and program shortcut icons. ?

Program files can also be deleted?:

Everyone is familiar with "C:\Program Files" because when installing a program, its default installation path is here, see below See what content there is that can be deleted. ?

C:\Program Files\Windows Update ?This directory is used for online upgrades and can be deleted. As long as you log in to the Windows Update upgrade website again to upgrade, this directory will be automatically rebuilt. ?

C:\Program Files\Windows Media Player\Skins ?This is the "skin" that comes with WMP. I believe many "skins" will not be used. It is better to leave only a few commonly used ones and put them Delete the rest. ? C:\Program Files\Common Files\Microsoft Shared\Stationery ?This is the stationery pattern in Outlook. Keep the ones that are useful and delete those that are no longer needed. If you don't use Outlook to send and receive emails, delete them all. ? Purpose: Delete unused components in the program.
