Description

Method and device for organizing registry files

technical field

The invention relates to the field of computer technology, in particular to a method and device for organizing registry files.

Background technique

The registry is the data file of all 32-bit hardware/drivers and 32-bit applications in the Windows operating system. It is a database of system information, which contains all configuration information of applications and computer systems, and the relationship between applications and document files. , the description, status and properties of the hardware device, and various status information and data. Registry files are also known as HIVE files. It is the physical storage form of registry information. The registry structure we see is presented to us after being read by the registry editor, and is composed of a group of files called HIVE. The Chinese name of HIVE is "Store Nest". Each HIVE file can be understood as a single registry tree.

Registry information is composed of several files stored on the hard disk according to a certain format. Modifying a registry item is essentially modifying the corresponding file. When the user installs new hardware, installs and uninstalls software, and modifies system settings, it will involve reading, writing, adding, and deleting operations in the registry. Wherein, when the registry information item is deleted, the corresponding physical storage space will be marked with a deletion mark. There will be many such spaces marked for deletion in the registry file. As writing and deleting are performed many times, a large number of fragments will be generated in the registry file. This kind of fragmentation generally does not cause problems in the system, but too much fragmentation will cause the system to search back and forth when reading and writing the registry, causing system performance to decline. In addition, excessive fragmentation may also lead to loss of registry information.

Therefore, a technical problem that urgently needs to be solved by those skilled in the art is how to effectively organize registry files so as to reduce fragments therein.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to Fig. 1, the registry file finishing method that the embodiment of the present invention provides comprises the following steps:

S101: Obtain the target file when the registry file needs to be sorted;

In practical applications, in order to determine whether the registry files need to be sorted, a startup entry can be provided for the user, and when the user sends a request for sorting the registry files through this entry, it will be used as an instruction that needs to sort the registry files , and then start the registry file sorting process. Alternatively, an automatic monitoring program can also be set, for example, the space occupied by the registry file can be monitored, and when the space occupied by the registry file reaches a preset threshold, the process of sorting the registry file can be started. Of course, the two can also be combined. For example, when it is monitored that the space occupied by the registry file reaches a preset threshold, a prompt will pop up to the user, informing the user that the space occupied by the registry file is too large, and ask the user whether to It is necessary to sort out the registry files, and if the user chooses to do so, start the process of sorting out the registry files. Once it is determined that the registry file needs to be sorted, the target file can be obtained first to prepare for the subsequent sorting.

Wherein, specifically when obtaining the target file, it may be to newly create an empty file, and use the empty file as the target file (of course, the empty file may be pre-created, or it may be necessary to organize the registry file created at the time). Or, in practical applications, the target file can also be a pre-acquired file with basic configuration information. The basic configuration information refers to some basic configurations for the user's computer. This basic configuration can be related to the operating system installed on the user's computer corresponding to the version number of the system (such as Windows XP SP3, etc.), that is to say, for computers with a certain version of the operating system installed, some basic configurations in the registry are usually the same, so you can target each Standard files are preset for different operating system version numbers, and such standard files can be used as target files when the registry files need to be sorted out. During specific implementation, the standard file can be pre-saved locally on the user's computer, or when the registry file needs to be sorted out, the corresponding standard file can be downloaded from the server side according to the system version number of the computer, and then used as Target file.

S102: Save the valid data in the original registry file to the target file, and generate a new registry file;

Due to the obtained target file, when the registry file is sorted out, the valid data in the original registry file can be transferred to the target file and saved. It is worth noting that there are both valid data and some invalid data in the original registry file (when an application is uninstalled, the data about the application that was written into the registry before may not be deleted, At this time, since the application program has been uninstalled, this kind of data becomes invalid data, which can also be called fragments), when transferring data to the target file, only valid data is transferred to the target file, therefore, the newly generated registry files will no longer contain invalid data. In other words, for the data in the original registry file, first determine whether it is valid data or invalid data (specifically, it can be judged according to whether the data has a deletion mark, or, because the data that is set as deleted usually does not have a display characteristics, therefore, open the corresponding HIVE file with a registry editor, and the data that can be seen are all valid. There is no need to identify invalid data therein), if it is valid data, it is saved in the target file, therefore, it is equivalent to clearing the fragments to avoid affecting system performance.

It should be noted that if the target file is a newly created empty file, all valid data in the original registry file can be directly transferred to the target file and saved. And if the target file is a file with basic configuration information as mentioned above, you can only transfer and save other valid information other than the basic configuration information to the basic configuration file. Therefore, it is beneficial to improve the efficiency of file organization and save time and system resources.

In addition, it should be noted that the effective data described in the embodiments of the present invention may also be data about some optimized configurations of the current system obtained after analysis based on the characteristics of the user's system version number and installed applications. , while sorting the registry file, in addition to saving the valid data in the original registry file to the target file, you can also save these optimized configuration data to the target file, so that the new registry file can be sorted At the same time, the system configuration is optimized to further improve system performance.

S103: Notify the operating system to use the new registry file as a registry file.

After a new registry file is generated, the operating system can be notified to use the file as a registry file. During specific implementation, after the new registry file is generated, the computer can also be restarted (or the user is prompted to restart), and after restarting, the computer will run with the new registry file. Of course, for the original registry file, since it no longer has the value of existence, it can be deleted. As for the deletion timing of the original registry file, it can be deleted after the new registry file is generated, or it can be deleted after restarting the computer.

It can be seen that in the registry file sorting method provided in the embodiment of the present invention, if the registry file needs to be sorted, the target file will be obtained, and then the valid data in the original registry file will be saved in the target file, so that A new registry file can be generated and then used as a registry file. In this process, since only valid data is saved to a new file, invalid data no longer exists in the new registry file, therefore, it is equivalent to sorting out registry fragments, which is beneficial to improve system performance.

In practical applications, since the registry file is usually composed of multiple HIVE files, each registry item corresponds to a HIVE file, and a registry item usually corresponds to a group, for example, the group name is "\REGISTRY \MACHINE\SOFTWARE" HIVE file, which is equivalent to the registry key corresponding to the application. When a new application is installed, the generated registry information will be written into the HIVE file. Or, the HIVE file with the group name "\REGISTRY\MACHINE\SYSTEM" is equivalent to the corresponding registry item of the system. When the configuration of hardware and other things in the system changes, the generated registry information will be written into the HIVE file middle. That is to say, in the registry file, different registry information is actually classified and saved, the same type of registry information corresponds to a HIVE file, and each HIVE file contains multiple registry information, With the new installation and uninstallation of the application program, the change of the system configuration, etc., invalid data may be generated in each HIVE file.

Therefore, in the embodiment of the present invention, if the newly created file is used as the target file, before creating a new file, you can also first search for the registry entries in the original registry file and their corresponding HIVE files, and then for each registry entry , create a new file respectively. Specifically, when sorting out the registry files, it can be done for each registry item. Wherein, for each registry item, the valid data in the original HIVE file can be stored in a newly created file corresponding to the registry item. In this way, finally, a newly created file can be obtained for each registry item, and only valid data is saved in the newly created file. At this time, these newly created files can be combined together to generate a new registry file.

It should be noted that in practical applications, the following phenomenon may also exist: when writing the registry, the computer will preferentially find a large enough contiguous free space in the HIVE file to store the information. If there is no large enough contiguous free space, several blocks are usually selected from the available storage space to store the data. This will result in the discontinuity of the same registry information in the physical storage space, and due to the discontinuity in the physical storage space, the registry information will be stored in different places, which will also cause the system to read data changes. slow.

Considering the above-mentioned phenomenon, when the embodiment of the present invention arranges the registry file, in addition to clearing invalid data, it can also be judged whether there is a discontinuous storage of the same registry information in the physical space in the original registry file. Phenomenon, if it exists, in the process of transferring effective data to the newly created file, the data of the same registry information that is scattered and stored in different locations on the disk in the original registry file can also be continuously stored. In this way, the performance of the system can be further improved.

In addition, in the case that the registry file is manually started by the user, in order to provide the user with a reference on whether to organize the registry file, the registry file can be analyzed first before sorting, and according to the value of each registry item The actual space occupied by the HIVE file and the space occupied by the valid data in the HIVE file determine the space occupied by each registry item after sorting (that is, the space occupied by valid data), and the optimized ratio after sorting (equivalent to Therefore, the ratio between the space occupied by invalid data and the total space occupied by the original file), and the space occupied by each registry item before and after sorting, and the optimized ratio after sorting are displayed to the user. That is to say, based on the information, the user can intuitively know how much optimization can be obtained if the registry file is sorted, and then decides whether to sort the registry file.

For example, first you can find all HIVE files from the Windows system and list them one by one, as shown in Figure 2, where "group name" represents the name of the HIVE file corresponding to each registry entry, and "current size" is Represents the size of the space currently occupied by each HIVE file (including the space occupied by invalid data). After the user clicks "Analyze Registry" in the upper right corner, each HIVE file can be analyzed, and the size and optimized ratio of each HIVE file can be calculated and displayed to the user, as shown in Figure 3. Next, if the user clicks the "Optimize Now" button, a prompt that the computer needs to be restarted can be given in the interface, as shown in FIG. 4 . If the user clicks "Yes", it means that the user has sent a request to organize the registry files. At this time, steps S101 to S103 can be performed to reassemble the physical storage structure and completely release the unusable small storage areas. Then restart the system and the registry defragmentation is complete.
