Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. 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 a first aspect, an embodiment of the present invention provides a method for saving a file, which can effectively improve the saving efficiency after editing the file.
As shown in fig. 1, the method for saving a file provided by the embodiment of the invention may include:
s11, responding to a file storage instruction, and acquiring editing operation undergone by an original file;
after the user opens the file, various editing operations may be performed on the file, such as entering text, modifying a format, adding comments, and the like. In the embodiment of the invention, when the file is to be saved by clicking a save button or automatically saving the system, the save operation is not directly executed, but the editing operation undergone by the original file is acquired before the save operation is executed. That is, between the current saving and the last saving, which editing operations are performed on the file by the user is obtained.
The files targeted by the file save instruction may include various files supporting incremental save and overwrite save, such as PDF files.
Alternatively, the editing operations that the original document undergoes may include one or more, wherein each editing operation may be performed one or more times.
S12, determining a storage mode corresponding to the editing operation according to the editing operation;
in this step, according to the different editing operations undergone by the original file, different storage modes can be adopted for file storage in a targeted manner, that is, the same original file undergoes different editing operations, the specific storage modes of the file may be different, and the most favorable file storage mode can be selected for file storage.
And S13, updating and storing the original file based on the determined storage mode.
After determining the saving mode corresponding to the editing operation, the original file can be saved by using the saving mode, and the saved content is written into the storage medium.
According to the file saving method provided by the embodiment of the invention, after the file saving instruction is received, the editing operation undergone by the original file can be obtained in response to the instruction, the saving mode corresponding to the editing operation is determined according to the different editing operations, and the original file is updated and saved by adopting different saving modes. Therefore, the file can be saved in an adaptive mode according to different editing operations undergone by the original file, and resources spent for saving the file are minimized on the basis of ensuring the correct content of the file, so that the saving efficiency of the file is effectively improved.
Specifically, in one embodiment of the present invention, before the editing operation undergone by the original file is acquired in response to the file saving instruction in step S11, the file saving method provided by the embodiment of the present invention may further include: marking the adopted editing operation when editing the file to form an operation record; correspondingly, the editing operation performed to obtain the original file in step S11 may specifically include: and acquiring editing operation undergone by the original file by querying the operation record.
The specific form of marking the editing operation is not limited, and various editing operations undergone by the original file can be sequentially recorded in a single file or data structure, and the corresponding editing operation mark can be marked on the mark.
It should be noted that in the embodiment of the present invention, the execution time and order of each editing operation do not need to be known, and the specific number of times each editing operation is executed does not need to be known, but only whether the editing operation is executed or not is known, so that the data size is small, and the data maintenance and the query are convenient.
After the editing operation undergone by the original file is acquired, in step S12, a storage manner corresponding to the editing operation may be determined according to the editing operation.
Optionally, in the embodiment of the present invention, the editing operations are various, and there may be various solutions how to form a correspondence between the editing operations and the saving modes, so as to improve the file saving efficiency. For example, different saving modes may be selected according to whether certain specific operations are included in the editing operation.
Specifically, in one embodiment of the present invention, step S12 may include, according to an editing operation, determining a saving mode corresponding to the editing operation:
if the editing operation comprises a preset operation, determining a storage mode corresponding to the editing operation to be saved in a rewriting manner; based on this, in step S13, the updating and saving the original file based on the determined saving mode includes: when the editing operation comprises a preset operation, the original file is entirely replaced by a first new file formed after the editing operation and written into a storage address;
if the editing operation does not comprise the preset operation, determining that the storage mode corresponding to the editing operation is incremental storage; based on this, in step S13, updating and saving the original file based on the determined saving mode may specifically include: under the condition that the editing operation does not comprise the preset operation, reserving the content of the original file in the storage address, and adding the operation content corresponding to the editing operation to the original file to form a second new file;
wherein the preset operation includes at least one of: adding a password operation, removing the password operation and deleting the password operation.
The add password operation may refer to encrypting the file contents, requiring the password to be entered the next time the file is reopened. The delete password operation may refer to decrypting the encrypted file content without entering a password the next time the file is reopened. The delete operation may refer to deleting any content in the file, such as deleting pages, text, pictures, annotations, and the like.
That is, in this embodiment, if any one or more of the operations of adding a password, removing a password, and deleting is included in the editing operation that the original file undergoes, then the original file is written to the save address by replacing the whole of the original file with the first new file formed after the editing operation in the overwrite save mode when the file is saved. If the editing operation, the password adding operation, the password releasing operation and the deleting operation of the original file are not included, an incremental storage mode can be adopted, the content of the original file is reserved in the storage address, and the operation content corresponding to the editing operation is added to the original file to form a second new file.
The rewriting and storing mode can recode the file content so as to realize the password adding operation or the password releasing operation, and after the file is deleted, the file content is relatively reduced, so that the workload of rewriting and storing can be reduced.
Besides the password adding operation, the password releasing operation and the deleting operation, the file can be saved in an incremental saving mode after other editing operations. The incremental saving mode only adds the newly added change after the original file content, and the incremental saving speed is higher because the newly added saved content is usually smaller.
In the above embodiment, the preset operation includes a password adding operation, a password releasing operation, and a deleting operation. Embodiments of the present invention are not limited in this regard and in other embodiments of the present invention, the preset operations may include more or fewer editing operations.
For example, in one embodiment of the present invention, according to the editing operation in step S12, determining the saving mode corresponding to the editing operation may include:
if the editing operation comprises a preset operation, determining a storage mode corresponding to the editing operation to be saved in a rewriting manner; based on this, updating and saving the original file based on the determined saving manner in step S13 may include: the original file is replaced by a first new file formed after the editing operation, and the original file is written into a storage address;
if the editing operation does not comprise the preset operation, determining a storage mode corresponding to the editing operation according to a comparison result of the file size of the original file and a preset threshold value; based on this, updating and saving the original file based on the determined saving manner in step S13 may include: the original file is entirely replaced by the first file formed after the editing operation and written into a storage address; or reserving the content of the original file in the storage address, and adding the operation content corresponding to the editing operation to the original file to form a second file;
the preset operation comprises a password adding operation and/or a password releasing operation.
That is, in this embodiment, the preset operation only includes an add password operation and/or a remove password operation, if the edit operation undergone by the original file includes an add password operation and/or a remove password operation, the file is saved in a manner of rewriting and saving, and if the edit operation undergone by the original file does not include an add password operation and/or a remove password operation, a further determination may be made as to what saving manner is adopted according to the size of the file.
Specifically, in one embodiment of the present invention, according to a comparison result between the file size of the original file and a preset threshold, determining the saving mode corresponding to the editing operation may specifically include:
if the file size of the original file is smaller than or equal to the preset threshold value, determining a storage mode corresponding to the editing operation for rewriting and storing;
and if the file size of the original file is larger than the preset threshold value, determining that the storage mode corresponding to the editing operation is incremental storage.
That is, if the original file size is smaller than or equal to the preset threshold, the file data size is smaller, and it does not take too long to save the file by rewriting the file once, so that the file can be saved by rewriting the file. If the file size of the original file is larger than the preset threshold, the file data size is larger, and the rewriting is more time-consuming, the file storage mode can be selected for file storage, so that the file storage efficiency is effectively improved while the file content is ensured to be correct and the balance is made between the file size and the time spent for file storage.
In the above embodiments, when the file saving mode is selected, whether the editing operation undergone by the original file includes the preset operation is detected, but the embodiment of the present invention is not limited thereto. In other embodiments of the present invention, different ways of saving may be performed depending on whether the editing operation is one of them.
In an embodiment of the present invention, according to the editing operation in step S12, the determining, by the storage manner corresponding to the editing operation, may specifically include:
if the editing operation is a page deleting operation, determining a storage mode corresponding to the editing operation to be saved in a rewriting manner; based on this, in step S13, updating and saving the original file based on the determined saving mode includes: the original file is replaced by a first new file formed after the editing operation, and the original file is written into a storage address;
if the editing operation is the operation of deleting the non-page, determining that the storage mode corresponding to the editing operation is incremental storage; based on this, in step S13, updating and saving the original file based on the determined saving mode includes: and reserving the content of the original file in the storage address, and adding the operation content corresponding to the editing operation to the original file to form a second new file.
In this embodiment, if the editing operation includes only the page deleting operation, the file content of the original file is greatly reduced after the page is deleted, so that more storage space is saved, and therefore, the file can be saved in a manner of overwriting. In contrast, if the editing operation includes only the operation of deleting the non-page, the file content of the original file can be reduced only by a small amount by the operation of deleting the non-page, and the saved storage space is limited, so that the file can be saved in an incremental saving mode, so that more file saving time can be saved.
Of course, in other embodiments of the present invention, the time consumed for file saving and the resources such as space may be balanced according to a variety of factors such as the file size and editing operation, for example, the product of the space saving rate and the time saving rate may be used as an index, and the file saving mode with the highest efficiency may be selected.
