Play Vista disk quota management, block the virus Trojan

This technical slightly stronger, may not be suitable for some beginners, in short, everyone will look down to understand, some features exist in Win7, Vista, there must be Its value and significance.

As you know, in most cases hacking remote systems must upload Trojans or backdoors to remote systems. Then, if you want to guard against it, you must think of one thing: How can we cut off this hacker's back road?

In fact, the disk quota feature in the NTFS file system can help users easily manage the disk space!

The following soft media make a graphic description of this function, which is valid for Windows 7, Vista, and XP.

1. Open “computer" (XP system is to open my computer), first, right click on an NTFS partition in the system, select “property", you can open the "partition attribute Set the window”, select the "quota" option, click “display quota setting", as shown below:

2, first check “ enable quota Management & rdquo; and & ldquo; refuse to give disk space to users exceeding the quota limit, then all quota options will become optional. Then select the "disk space limit" option, then we can specify the size of the disk space used by the user in the system, such as 1KB. So if the user passes a file larger than 1KB in the partition, then the file will It was rejected by the system and could not be successfully transferred to the partition.

3, under the "disk space limit" option, there is a "warning level" option, if the file size of the warning level is set, when the user is using The size of the warning level is exceeded during disk space and the user is prompted to exceed the warning level in the disk quota.

4, the last user can tick the "record event when the user exceeds the quota limit" and "record the event when the user exceeds the warning level", so if there are other users in the system beyond The warning level and quota limit of the partition, the system will automatically record these events into the system log, which is very beneficial for the administrator to monitor the system partition space.

5, after completing the configuration options, click the "OK" button under the window to complete the initial configuration of the disk quota function, then users can be surprised to find that there are still many The partition of the remaining space, the available space is now running out! !

6. At this time, the user has been unable to write a file larger than the quota to this partition. And this configuration is effective for all users in the system, including users in the Administrators group.

7, but if the configuration is effective for all users in the system, it is obviously inconvenient for the user to operate the system, and the disk quota function also provides a function for dividing the space for different users. The implementation method is also very simple.

First, click the “Quota Item” button in the quota configuration window. At this time, the “Partition Quota Item” window will pop up. Click the “Quotas” option at the top left of the window, as shown below. :

Then, select the “New Quota Item”, as shown below,

A selection will pop up. The user's window, in which to fill in or select a user name in the system (such as Ruanmei.com), after determining, there will be an option for the user to use the disk space limit, and everyone can be based on the user's permissions in the system And the use case, reasonably specify the use space for the user, so that the configuration does not affect the normal operation of the system, but also strengthens the security of the system.
