I suggest you don't understand and don't tamper with disk C, otherwise there will be problems. I suggest you use software to give you a way to delete the contents of disk C. There is a functional encyclopedia in 360 security guards-C disk moving-tick off all the contents and move. And kill Trojans, enter the program to delete and add programs, and delete useless programs inside. Of course, those useful systems cannot be deleted. Cleaning up garbage and traces, system disk optimization and registry optimization can also improve the network speed. My security guard is 8.3 Bart.

6, 30 seconds to clear the garbage from your computer (make your computer fly like a fly)
To surf the internet easily and smoothly, have you found that the available space of your computer system disk is decreasing day by day? Are you getting slower every day like the old monkey king?
That's right! During the installation and use of Windows, there will be a lot of junk files, including temporary files (such as *). Tmp and *. _mp), log file (*. Log), temporary help file (*. Gid), disk check file (*. Chk), temporary backup files (such as *. Old and *. Bak) and other temporary documents. Especially, if IE's temporary folder "Temporary Inter Files" is not cleaned for a period of time, the cache files in it sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuable disk space, but also make the system run at a snail's pace. I believe you can't stand this! Therefore, it is necessary to clear up the blockage of LJ files in time, keep the system slim and surf the Internet easily and smoothly! Come on, friends, let's go to cclean quickly now! Here are the steps. It's simple. Just two steps!
Click Start → Program → Attachment → Notepad in the lower left corner of the computer screen, copy the following words, click Save As, select the desktop as the path, save all files as types, and file name is cleansystemlj.bat. Finish. Remember that the suffix must be. Bat, good! Your garbage cleaner has been made successfully!
Double-click it to quickly clean up junk files in less than a minute.

Note: LJ means garbage! This move is even more powerful than those so-called optimization masters! Most importantly, no matter in the company's default system environment or at home, computers will not destroy system files.
Seven, shut down and restart as long as 1 second.
If you want Windows XP to shut down instantly, you can press CTRL+ALT+DEL, and then click Shutdown → Shutdown in the pop-up task manager. Hold down CTRL at the same time, and you will find that the system is shut down in less than 1 second, almost in the blink of an eye. Similarly, if you choose "restart" in the "shutdown" menu, you can also restart quickly.
Eight. There is also one that can increase memory. I'm IE8. Toolbar -IE Options-General-Check the box under Browse History-Delete-Check All-Delete-OK,
Eight. The key is that you can't have too many plug-ins, which is mine, and how to optimize it is also because of this, that is, there are too many things in your program, or there are too many things added or deleted in your program, so you can't bear to delete them. Therefore, deleting some useless or uncommon things can improve the network speed. Another point is not to put everything on the C disk, which is the system disk. Small memory, slow network speed, 360.

Search input mdm*. Inf (2 1.6M) is used for things that are no longer used.
Search input prn*. Inf (78 1M) prn starts all printer drivers, which I believe most people don't need. Even if you have a printer, you will buy one with a driver and delete it.
Note: prnms001.inf/prnoc001.inf/prnms002.inf is not a printer driver, so it is recommended to keep it.

Method 1: Open the drive C: 1: Cache folder with third-party software such as file manager. It is a cache directory, so it is recommended that you empty it regularly. 2: All temporary folders are temporary directories. Suggest emptying them.
4. The data directory installed on disk C is the installation directory of the software, which can be cleared.
What about method two and method three? Is this the c drive of win7? Why can't I find the folder of dmgr, data and cache? I typed too fast just now, and there was no "one" Please try these first. By the way, if you want more space on drive C, you can compress it or use Disk Cleanup to free up more space. Can I use third-party software? Don't want to pretend? Of course, first of all, I apologize. I just said XP, and the following WIN7g is1.c: all files downloaded under the distribution of Windows software. 2. Disk cleaning, system shutdown and recovery. 3.c: All files under Windows temp. 4.cookies In the inter option, the history has been deleted. 5.hiberfil.sys: Method: Run cmd.exe as an administrator to open a command line window, and then run: powercfg -h off. Note that the hidden file of hiberfil.sys left in drive C can be deleted directly after being unhidden. 6. Virtual memory page file. Sys: Windows system, including 7, the default setting is 1.5 times the size of physical memory, which is used as a paging exchange file. If you are the size managed by the system, then this volume is automatically changed and tends to get bigger and bigger. If the physical memory is less, only 5 12m or 1g, you can choose to keep this file. If you keep this file, I suggest you put it in another partition, not together with the system disk C, otherwise you still need to delete it manually when making Ghost or other backups. It is suggested that the size must be specified, that is, 1.5 times the physical memory size of Ram. If your memory is more than 2G, I suggest you turn off the virtual memory function directly, and you will find that your whole Windows system is "flying". Method of setting virtual memory: Click System in Control Panel-Classic View, click Advanced System Settings on the left, click First Setting Performance, click Advanced, and then click Settings in Virtual Memory. Note that you can directly remove and delete the hidden pagefile.sys file on drive C. 7. Application cache brought by Superfetch function: In Windows 7 system, the new technical features of Superfetch are used. Cleaning method: directly delete all files in the c:\windows\prefetch folder. 8. Temporary files generated by applications: generally stored in the windows\temp folder. And the cleaning method in the temp folder of the user folder: just delete all files in the folders c:\windows\temp and C: \ users \ your user name \ appdata \ local \ temp. Or delete system garbage with one click in Vista Optimizer. 8. Temporary files generated by browsers such as IE: Cleaning method: In the Inter option of the control panel, just delete cookie and IE temporary files; 9. System Restore, System Volume Information Folder: System Volume Information Folder, whose Chinese name can be translated as "System Volume Label Information". This folder stores the backup information restored by the system.
The files on disk C are as follows and can be deleted:
C: you can delete all files (user temporary files) under the user name Local settingstemp;
All files (keep index) and set user name cookies under C:C:Documents can be deleted;
C: You can delete all files (page files) under C: documents and temporary files for setting local settings;

Files under Windows software distribution download can be deleted;
C: C: dll document under C:WINDOWSSystem32dllcache, which is a spare dll document, and can be deleted as long as the installation file is copied;
C: You can delete the (hardware backup file) under C:windows driver cache 386.
If you upgrade windows updade, you can delete the hidden files starting with $u under C:windows.
After deleting the above files, the space on drive C will be greatly increased and the computer will be faster.
What files can be deleted from drive C in win7 system? 1. c:Windows software distributes all downloaded files.
