Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to create an uncompressed file in a disk without changing the compression attribute of the disk and ensure that the disk test can run normally, embodiments of the present invention provide a method for creating an uncompressed file, a disk test method, a device, an electronic apparatus, and a computer readable storage medium.
The following describes a method for creating an uncompressed file according to an embodiment of the present invention.
The method for creating the uncompressed file provided by the embodiment of the invention can be applied to any electronic equipment, such as a computer, a processor, a tablet computer and the like, and is not particularly limited herein. For convenience of description, hereinafter, referred to as an electronic device. It should be noted that, the "file" herein may be a file or a folder.
As shown in fig. 1, a method for creating an uncompressed file, the method comprising:
s101, creating a target file in a target disk, and storing a file handle of the target file;
in this embodiment, a target file may be created in a target disk compressed volume, and a file handle of the target file may be saved;
s102, acquiring attribute information of the target file based on the file handle;
And S103, when the attribute information comprises the compression attribute, removing the compression attribute to obtain an uncompressed file.
Therefore, in the scheme provided by the embodiment of the invention, the electronic device can create the target file in the target disk, store the file handle of the target file, acquire the attribute information of the target file based on the file handle, and remove the compression attribute when the attribute information comprises the compression attribute to obtain the non-compression file. By the method, the non-compressed file can be created in the disk under the condition that the compression attribute of the disk is not changed, and the disk test can be ensured to run normally.
In the step S101, the electronic device may create the target file in the target disk, and in one embodiment, the electronic device may create the target file in the target disk compressed volume after the user compresses the target disk, for later use in performing the disk test. In another embodiment, it is reasonable that the electronic device may create a target file in the target disk for disk testing when a test instruction for the target disk is obtained.
The method for creating the target file in the target disk may be any file creation method in the file processing field, which is not specifically limited herein.
The electronic device may create the target file in the target disk, and then may save a file handle of the target file, where the file handle is used to indicate a creation location, that is, a storage location, of the target file, and is a pointer to the file storage location, and according to the storage location indicated by the file handle, the electronic device may find the target file.
Next, in order to determine whether the target file has a compression attribute, the electronic device may acquire attribute information of the target file based on the file handle, that is, perform step S102 described above. The attribute information is information capable of representing the attribute of the target file, and may include information such as a compression attribute, a file size, a creation time, a file type, and a security setting.
Furthermore, the electronic device can determine whether the attribute information of the target file includes a compression attribute, and when the attribute information includes the compression attribute, the attribute information indicates that the target file is a compression file, so that in order to ensure that the subsequent disk test can be performed smoothly, the electronic device can remove the compression attribute, and the non-compression file can be obtained. If the attribute information does not include the compression attribute, it is indicated as an uncompressed file, and the target file at this time is the uncompressed file to be created.
As shown in fig. 2, the step of creating the target file in the target disk and saving the file handle of the target file may include:
s201, a file creation interface is called to create a target file at a preset storage position;
when creating the target file, the electronic device may call a file creation interface to create the target file at a preset storage location. The preset storage position is any storage position in the target disk. In one embodiment, the electronic device may create the target file through a system underlying file IO interface, e.g., the target file may be created at a preset storage location in the target disk using a CreateFile interface.
S202, acquiring a file handle of the target file returned by the system, and storing the file handle in a memory.
After the target file is created, the system returns a file handle of the target file, and the file handle can be saved in the memory for later use.
It can be seen that, in this embodiment, the electronic device may call the file creation interface to create the target file at the preset storage location, obtain the file handle of the target file returned by the system, and store the file handle in the memory. Thus, the target file can be smoothly created in the target disk, and an accurate file handle can be obtained.
As an implementation manner of the embodiment of the present invention, the step of obtaining the attribute information of the target file based on the file handle may include:
and calling an attribute acquisition function to acquire the attribute information of the target file from the storage position indicated by the file handle.
When acquiring the attribute information of the target file, the electronic device may call an attribute acquisition function to acquire the attribute information of the target file from the storage location indicated by the file handle. In one embodiment, the electronic device may obtain the attribute information of the target file by calling the GetFileAttributes function through the system. The attribute information obtained through the GetFileAttributes function is shaped unsigned, so that the electronic equipment can conveniently operate.
After the electronic device obtains the attribute information of the target file, the attribute information can be stored in the program memory for subsequent use.
Therefore, in this embodiment, the electronic device may call the attribute obtaining function to obtain the attribute information of the target file from the storage location indicated by the file handle, where the obtained attribute information may facilitate subsequent operations, and ensure smooth creation of the uncompressed file.
As shown in fig. 3, before the step of removing the compressed attribute when the attribute information includes the compressed attribute to obtain the uncompressed file, the method further includes:
S301, judging whether attribute information of the target file comprises a compression attribute, and if so, executing step S302; if not, go to step S303;
after the electronic device obtains the attribute information of the target file, it may determine whether the target file includes a compression attribute, and if the target file includes the compression attribute, it indicates that the target file is a compressed file, and in order to obtain a non-compressed file, the electronic device may execute step S302. If the compression attribute is not included, indicating that the target file is a non-compressed file, step S303 may be performed.
S302, removing the compression attribute to obtain an uncompressed file.
Since the target file has the compression attribute at this time, the compression attribute of the target file can be removed, and thus the uncompressed file can be obtained.
S303, determining the target file as an uncompressed file.
Since the target file does not have the compression attribute at this time, it can be determined that the target file is an uncompressed file to be created.
It can be seen that, in this embodiment, before removing the compression attribute to obtain the non-compression file, the electronic device may determine whether the attribute information of the target file includes the compression attribute, and if so, execute the step of removing the compression attribute when the attribute information includes the compression attribute to obtain the non-compression file. In this way, it is possible to accurately and quickly determine whether the compression attribute of the target file needs to be removed.
As shown in fig. 4, the step of determining whether the attribute information of the target file includes the compression attribute may include:
s401, judging whether ATTRIBUTE information of the target FILE contains a file_ATTRIBUTE_COMPRESSIED bit; if so, step S402 is performed; if not, step S403 is performed.
If the ATTRIBUTE information of the FILE includes the file_attribute_compressed bit, it indicates that the FILE has a COMPRESSED ATTRIBUTE, so the electronic device may determine whether the ATTRIBUTE information of the target FILE includes the file_attribute_compressed bit, and if so, may execute step S402.
If the file_attribute_compressed bit is not included, it indicates that the target FILE does not have a compression ATTRIBUTE, and then step S403 may be performed.
S402, determining that the attribute information of the target file comprises compression attributes;
s403, determining that the attribute information of the target file does not comprise a compression attribute.
It can be seen that, in this embodiment, the electronic device may determine whether the ATTRIBUTE information of the target FILE includes a file_attribute_compressed bit, if so, determine that the ATTRIBUTE information of the target FILE includes a compression ATTRIBUTE, and if not, determine that the ATTRIBUTE information of the target FILE does not include a compression ATTRIBUTE. In this way, it can be accurately determined whether the attribute information of the target file includes the compression attribute.
As an implementation manner of the embodiment of the present invention, the step of removing the compression attribute may include:
and calling a parameter transfer function, and transferring preset parameters to the attribute information of the target file based on the storage position indicated by the file handle.
In the case that the target file has a compressed attribute, to remove the compressed attribute of the target file, the electronic device may call a parameter transfer function to transfer preset parameters to attribute information of the target file to instruct the system to disable enabling of the disk compressed attribute for the target file. The preset parameters are used for indicating that the system prohibits enabling the disk compression attribute to the target file.
Specifically, the electronic device may call the DeviceIoControl function through the disk bottom IO interface, and transfer the preset parameter communication_format_none to the attribute information of the target file based on the storage location indicated by the file handle of the target file, so that the target file will not be compressed in the target disk.
It can be seen that, in this embodiment, the electronic device may call the parameter transfer function, and transfer the preset parameter to the attribute information of the target file based on the storage location indicated by the file handle, so that the compressed attribute of the target file may be removed for use in the subsequent disk test.
Corresponding to the method for creating the uncompressed file, the embodiment of the invention also provides a disk testing method. The following describes a disk testing method provided by the embodiment of the invention.
As shown in fig. 5, a disk testing method, the method includes:
s501, when a test instruction for a target disk is acquired, creating an uncompressed file in the target disk;

By the method, the non-compressed file can be created in the disk under the condition that the compression attribute of the disk is not changed, and the disk test can be ensured to run normally.
In the above step S501, when the electronic device acquires the test instruction for the target disk, an uncompressed file may be created in the target disk. The test instruction may be sent by the user through a preset user interface, for example, the electronic device may display a "start test" button in the interface, and when the user triggers the button, the test instruction sent by the user may be obtained.

The test on the target disk may be a read-write test, such as a sequential read-write, a random read-write speed test, a multithreaded file read-write test, and the like, which is not specifically limited herein. Because the electronic equipment tests the target disk based on the created non-compressed file, the problem of abnormal test does not occur, the disk test can be ensured to be smoothly carried out, and an accurate test result is obtained.
