Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides a mobile terminal file storage method, which is used for a mobile terminal, and as shown in fig. 1, the method includes:
And 102, when the external memory card does not meet the storage requirement, displaying prompt information, wherein the prompt information is used for indicating to execute specified operation on the external memory card, and the specified operation comprises replacement operation or formatting operation.
And 103, after detecting that the specified operation is executed on the external memory card, storing the file to be stored in the external memory card.
In summary, according to the file storage method of the mobile terminal provided in the embodiment of the present invention, when a to-be-stored file that needs to be stored in the external memory card is detected, it is determined whether the external memory card meets a storage requirement of the to-be-stored file, and when the external memory card does not meet the storage requirement, a prompt message is displayed, where the prompt message is used to instruct the external memory card to perform a specified operation, where the specified operation includes a replacement operation or a formatting operation.
An embodiment of the present invention provides another mobile terminal file storage method, which is used for a mobile terminal, and as shown in fig. 2, the method includes:
By way of example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, or the like. In order to store the file to be stored in the external memory card, the external memory card needs to be inserted into the mobile terminal first. Then, the mobile terminal performs an initialization operation on the external memory card, for example, an input-output (IO) voltage of the external memory card. And then, carrying out mounting operation on the external memory card through the mobile terminal. After the external memory card is successfully mounted, memory card data of the external memory card can be accessed through the mobile terminal, and the memory card data can include protocol levels, IO voltages, values of file clusters set when the external memory card is formatted, and the like.
In the embodiment of the present invention, the target protocol level of the external memory card may be 3.0, 2.0, or 1.0, and correspondingly, the external memory card may be SD3.0, SD2.0, or SD 1.0. Wherein the 3.0 is higher than the 2.0, and the 2.0 is higher than the 1.0.
Table 1 exemplarily shows a correspondence between the protocol level and the storage requirement, referring to table 1, where the storage requirement corresponding to the first level is a, for example, when the first level is 3.0, a may be that an IO voltage of the external memory card belongs to a preset voltage range corresponding to the first level, and a value of a file cluster set when the external memory card is formatted is not less than a preset cluster value. The storage requirement corresponding to the second level is B, for example, when the second level is 2.0, B may be that the writing speed of the external memory card is not less than the preset speed corresponding to the second level, and the value of the file cluster set when the external memory card is formatted is not less than the preset cluster value. Assuming that the preset protocol level corresponding to the target protocol level of the external memory card obtained in step 201 is 2.0, the storage requirement of the target protocol level obtained after the mobile terminal queries table 1 is B: the writing speed of the external memory card is not less than the preset speed corresponding to the second level, and the value of the file cluster set when the external memory card is formatted is not less than the preset cluster value.
TABLE 1
| Protocol level | Storage requirements |
| First class | A |
| Second level | B |
The preset protocol levels corresponding to the target protocol level of the external memory card are different, and the mode that the mobile terminal judges whether the external memory card meets the storage requirement of the target protocol level is different.
For example, when the preset protocol level corresponding to the target protocol level of the external memory card is a preset first level, step 203 may include:
when the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first grade, determining that the external memory card does not meet the storage requirement of the target protocol grade; or when the IO voltage of the external memory card belongs to the preset voltage range corresponding to the first level and the value of the file cluster set when the external memory card is formatted is smaller than the preset cluster value, determining that the external memory card does not meet the storage requirement of the target protocol level. Wherein the first rating is 3.0. After the external memory card is successfully mounted, memory card data of the external memory card can be accessed through the mobile terminal, and the memory card data can include IO voltage, a value of a file cluster set when the external memory card is formatted, and the like. The preset voltage range corresponding to the first level may be (V1- Δ V, V1+ Δ V), and V1 may be 1.8V (volts), and Δ V is greater than 0. For example, if Δ V is 0.5V, the preset voltage range is (1.3,2.3), and if the IO voltage of the external memory card is 3.3V, the mobile terminal may determine that the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first class. Assuming that the IO voltage of the external memory card is 1.9V, the mobile terminal may determine that the IO voltage of the external memory card belongs to a preset voltage range corresponding to the first class.
In the related art, a file cluster is the minimum unit used by a file system of a mobile terminal to complete data operations, and files are all accessed in units of file clusters. The larger the value of a file cluster, the smaller the number of logical blocks of a file of a fixed size, the fewer the number of addressing times required, the shorter the addressing time required, and the greater the speed at which data can be manipulated. It is generally necessary to set a value of a file cluster when performing a formatting operation for an external memory card. Therefore, in the method, it may be further determined whether the external memory card meets the storage requirement of the target protocol level based on whether a value of a file cluster set when the external memory card is formatted is smaller than a preset cluster value. Illustratively, the preset cluster value is 32K (1K equals 1024 bytes). Assuming that the IO voltage of the external memory card is 1.9V and the value of the file cluster set when the external memory card is formatted is 30K, since 1.9V belongs to the preset voltage range (1.3,2.3), and 30K is less than 32K, the mobile terminal can determine that the external memory card does not meet the storage requirement of the target protocol level, and then prompt the user to increase the value of the file cluster.
For another example, when the preset protocol level corresponding to the target protocol level of the external memory card is a preset second level, step 203 may include:
when the writing speed of the external storage card is lower than the preset speed corresponding to the second grade, determining that the external storage card does not meet the storage requirement of the target protocol grade; or, when the writing speed of the external memory card is not less than the preset speed corresponding to the second level, and the value of the file cluster set when the external memory card is formatted is less than the preset cluster value, determining that the external memory card does not meet the storage requirement of the target protocol level. Wherein the second rating is 2.0. In order to determine the writing speed of the external memory card, a file with a specified size may be written into the external memory card, the writing duration of the file is recorded, the writing speed of the external memory card is calculated according to the size of the file and the writing duration, and then it is determined whether the calculated writing speed is less than the preset speed corresponding to the second level. For example, the preset speed for the second level may be 10MB/s (mega/second). Assuming that the calculated writing speed of the external memory card is 9MB/s, the mobile terminal may determine that the external memory card does not meet the storage requirement of the target protocol level because 9MB/s is less than 10 MB/s. Further, whether the external memory card meets the storage requirement of the target protocol level may also be determined based on whether a value of a file cluster set when the external memory card is formatted is smaller than a preset cluster value. Illustratively, the preset cluster value is 32K. Assuming that the calculated writing speed of the external memory card is 12MB/s and the value of the file cluster set when the external memory card is formatted is 30K, the mobile terminal can determine that the external memory card does not meet the storage requirement of the target protocol level because 12MB/s is greater than 10MB/s and 30K is less than 32K, and then prompt the user to increase the value of the file cluster.
When the writing speed of the external memory card is not less than the preset speed corresponding to the second level and the value of the file cluster set when the external memory card is formatted is not less than the preset cluster value, the mobile terminal may determine that the external memory card meets the storage requirement of the target protocol level.
For another example, when the preset protocol level corresponding to the target protocol level of the external memory card is the preset third level, the mobile terminal may directly determine that the external memory card does not meet the storage requirement of the target protocol level. Wherein the third rating is 1.0.
And step 204, when the external memory card does not meet the storage requirement of the target protocol level, displaying prompt information.
The prompt message is used for indicating to execute a specified operation on the external memory card, and the specified operation comprises a replacement operation or a formatting operation.
For example, when the preset protocol level corresponding to the target protocol level of the external memory card is a preset first level, the first level is 3.0, and on one hand, when the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first level, the prompt information displayed by the mobile terminal may be used to instruct to perform a replacement operation on the external memory card. If a user uses the mobile terminal to record a video, if the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first level, a pause phenomenon may occur in the video recording process. If the user uses the mobile terminal to take a picture, if the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first level, a pause phenomenon may occur in the process of taking a picture. Therefore, when the IO voltage of the external memory card does not belong to the preset voltage range corresponding to the first level, the prompt information displayed by the mobile terminal can be used for indicating to execute replacement operation on the external memory card, prompting a user to replace the external memory card in time, and avoiding the occurrence of a pause phenomenon. For example, the mobile terminal may display the prompt message 30 in a pop-up window manner, as shown in fig. 3. On the other hand, when the IO voltage of the external memory card belongs to the preset voltage range corresponding to the first level and the value of the file cluster set when the external memory card is formatted is smaller than the preset cluster value, the prompt message displayed by the mobile terminal is used to instruct the external memory card to perform formatting operation to increase the value of the file cluster, thereby reducing the number of addressing times required for operating data, shortening the required addressing time, and increasing the speed of operating data.
For example, when the preset protocol level corresponding to the target protocol level of the external memory card is a preset second level, the second level is 2.0, and on one hand, when the writing speed of the external memory card is lower than the preset speed corresponding to the second level, the prompt information displayed by the mobile terminal may be used to instruct to perform a replacement operation on the external memory card. If the user uses the mobile terminal to record a video, if the writing speed of the external storage card is less than the preset speed corresponding to the second level and the writing speed of the external storage card is low, the video cannot be recorded into the external storage card in real time, a pause phenomenon can occur in the video recording process, and finally the video recording fails and the video is damaged. If the writing speed of the external memory card is lower than the preset speed corresponding to the second level, a pause phenomenon may occur during the photographing process. Therefore, when the writing speed of the external memory card is lower than the preset speed corresponding to the second level, the prompt information displayed by the mobile terminal can be used for indicating to execute the replacement operation on the external memory card, and prompting the user to replace the external memory card in time. On the other hand, when the writing speed of the external memory card is not less than the preset speed corresponding to the second level and the value of the file cluster set when the external memory card is formatted is less than the preset cluster value, the prompt message displayed by the mobile terminal is used for indicating that the formatting operation is executed on the external memory card to increase the value of the file cluster, so that the number of addressing times required by data operation is reduced, the required addressing time is shortened, and the speed of data operation is increased.
For example, when the preset protocol level corresponding to the target protocol level of the external memory card is a preset third level, the third level is 1.0, and the prompt information displayed by the mobile terminal is used for instructing to execute a replacement operation on the external memory card and prompting the user to use the external memory card of another protocol level.
In addition, when the mobile terminal determines that the external memory card meets the storage requirement of the target protocol level, the mobile terminal does not display corresponding prompt information, so that the effect of saving electric quantity is achieved.
And after detecting that the specified operation is executed on the external memory card, the mobile terminal stores the file to be stored in the external memory card. Because the external memory card which does not meet the storage requirement of the file to be stored has executed the replacement operation or the formatting operation, after the external memory card is detected to execute the specified operation, the file to be stored is stored in the external memory card, so that the file storage failure can be avoided.
It should be noted that, the sequence of the steps of the file storage method for a mobile terminal provided in the embodiment of the present invention may be appropriately adjusted, and the steps may also be increased or decreased according to the circumstances, and any method that can be easily changed by a person skilled in the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention, and therefore, no further description is given.
In summary, according to the file storage method of the mobile terminal provided in the embodiment of the present invention, when a to-be-stored file that needs to be stored in the external memory card is detected, it is determined whether the external memory card meets a storage requirement of the to-be-stored file, and when the external memory card does not meet the storage requirement, a prompt message is displayed, where the prompt message is used to instruct the external memory card to perform a specified operation, where the specified operation includes a replacement operation or a formatting operation.
