Note: Losing weight here does not mean that we must minimize the system, because our hard disk is not small now, and the space of1G20G is not bad. Our goal is to minimize drive C. So! We try not to delete files that can be transferred to other disks and still be used normally. Try to transfer it instead of deleting it. Drive C is small, looks refreshing and easy to back up.

After the system is installed, put it into virtual memory, personal documents, temporary files, etc. On other disks first, because

One: you don't need them (virtual memory, temporary files) when backing up.

Two: In order to avoid the loss of data (personal documents) when there is a problem with the C drive.

When backing up, clean the disk first, turn off hibernation, and try to make the smallest backup.

All files, such as videos, audio and pictures, can be safely deleted. If you are not sure whether you want to delete other system files, you can compress them. Generally, it can be compressed to about 60% of the original, and the effect is good. Unusual files, such as drivers, can be compressed. You can compress the whole C:\* if you like.

C:\ Windows \ Web \ wallpaper

It's the wallpaper that comes with Windows. You can delete it or transfer it to another disk if you don't need it. Can be safely deleted (45.5m)

c:\ Windows \ System32 \ DriverStore \ file repository

This folder contains the driver backup that comes with Windows, and it is 1.05438+0g, which is the focus of our weight loss. Most of them are not what we need, but some of them are what we need. We don't need to delete them all at once, but we can delete them selectively.

Generally speaking, device drivers such as video cards, sound cards and network cards can be deleted, because they will not be used after being installed once, that is, they need to be updated, and they are also used to drive the home, and their own drivers are very old. USB device drivers such as USB flash drive, USB mouse, keyboard, etc. must be kept, otherwise the USB flash drive may not be used when plugged in.

Open this folder and you can see a lot of *. Inf files, we will delete some of them which are larger and unnecessary.

ati*。 Inf (14.6m)

Without AMD/ati chipset and graphics card, you can delete AMD/ATI chip graphics card and motherboard driver. Even if it is used, it has already been installed for you when installing the system, and you will have to go to the driver's house to upgrade the new driver in the future, so you can delete it.

mdm*。 inf(2 1.6M)

Modem driver, something that no one uses now, if you want to use it, you installed it when you installed the system, and you can delete it without secondary installation.

nv*。 INF(94.9 m)

With AMD/ATI, it can be deleted.

prn*。 inf(78 1M)

Where is the big head? The drivers at the beginning of prn are all printers. I believe most people don't need it. Even if they have a printer, they will have a driver when they buy it. Delete it!

Prnms001.inf/prnoc001.inf/prnms002.inf is not a printer driver, so it is recommended to keep it.

After deleting the above driver files, compress and store other files. At this point, the folder is reduced to 178M, and the weight loss is successful!

Of course, if you want to delete this folder directly, the system will prompt you that you don't have permission, so we need to get this permission. First, right-click C: \ Windows \ System32 \ DriverStore \ File Repository-Properties. First, we will take ownership of the folder, click Security-Advanced-Owner, then click Edit-Advanced Other Users or Groups, and enter your user name in the selected object name, or click Advanced-Search Now, select your user name and confirm. Then choose to replace the child container and the owner of the object. If this option is not selected, we only have the ownership of this folder, but not its subfolders and files inside, and then apply -OK, so that we have the ownership of this folder, because the ownership of this folder used to belong to the system, not ours. Click Permission-Edit-Add again, fill in your user name or use Advanced-Search immediately, confirm, then click User Name-Edit, check the "Full Control/Allow" box, and then check the box to replace the existing inheritable permissions on all descendants with permissions that can be inherited from this object (I depend on Microsoft, it's really uncivilized, and it can be applied to all subfolders and files in one sentence), just like before. Ok, you can delete the folders in it at will.

Installed programs need to be uninstalled and modified. If deleted, there will be problems in uninstalling and modifying some programs. If you are sure that the program does not need to be uninstalled after installation, you can delete it, otherwise it may not be deleted in the future (but it can also be reinstalled and deleted), so delete it, depending on the number of installed programs, ranging from tens to hundreds of meters.

C:\ProgramData

Some programs will put some files in when they are installed to see if they need to be deleted. For example, after I install iTunes, the folder C: \ Program Data \ Apple Computer \ Installer Cache \ iTunes 7.0.2.16 will appear, which is actually an installation file and can be deleted. However, some files are needed when the software runs, so we can only delete the installation files inside. If we are not sure, it will not work. Depending on the situation, it can save tens to hundreds of meters of space.

Note that only the software installation backup can be deleted, and nothing else can be deleted.
