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 only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, embodiments of the present invention provide a file saving method, which can effectively improve saving efficiency after editing a file.
As shown in fig. 1, a file saving method provided in an embodiment of the present invention may include:
s11, responding to the file saving instruction, and acquiring the editing operation of the original file;
after the user opens the file, the user may perform various editing operations on the file, such as entering text, modifying format, adding comments, and the like. In the embodiment of the invention, when the file is saved by clicking the save button or automatically saving the system, the save operation is not directly executed, but the editing operation of the original file is acquired before the save operation is executed. That is, it is obtained what editing operation the user has performed on the file between the save this time and the save last time.
The files for which the file saving instruction is directed may include various files supporting incremental saving and overwrite saving, such as PDF files.
Alternatively, the editing operation undergone by the original file may include one or more types, wherein the number of times of execution of each editing operation may be one or more.
S12, determining a storage mode corresponding to the editing operation according to the editing operation;
in this step, different saving manners may be adopted for saving the file according to different editing operations experienced by the original file, that is, the specific saving manners of the file may be different if the same original file undergoes different editing operations, and the most favorable file saving manner may be selected for saving the file.
And S13, updating and saving the original file based on the determined saving mode.
After the storage method corresponding to the editing operation is determined, the original file can be stored by using the storage method, and the stored content can be 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 of the original file can be acquired in response to the instruction, the saving mode corresponding to the editing operation is determined according to the difference of the editing operation, and the original file is updated and saved by adopting different saving modes. Therefore, the files can be stored in an adaptive mode according to different editing operations of the original files, and resources consumed for storing the files are minimized on the basis of ensuring the correct contents of the files, so that the file storage efficiency is effectively improved.
Specifically, in an embodiment of the present invention, before the step S11, in response to the file saving instruction, acquiring the editing operation undergone by the original file, the file saving method provided in an embodiment of the present invention may further include: marking the adopted editing operation when editing the file to form an operation record; accordingly, the editing operation performed on the original file acquired in step S11 may specifically include: and acquiring the editing operation of the original file by inquiring the operation record.
The specific form of marking the editing operation is not limited, and various editing operations undergone by the original file may be sequentially recorded in a single file or data structure, or an operation mark may be marked on the identifier of the corresponding editing operation.
It should be noted that, in the embodiment of the present invention, it is not necessary to know the execution time and the sequence of each editing operation, nor to know the specific number of times each editing operation is executed, but only to know whether the editing operation has been executed, so that the data size is small, and the data maintenance and the query are very convenient.
After the editing operation performed on the original file is acquired, in step S12, a saving mode corresponding to the editing operation may be determined according to the editing operation.
Optionally, in the embodiment of the present invention, there are many kinds of editing operations, and how to form a corresponding relationship between the editing operation and the saving manner is to improve the file saving efficiency, and there may be a variety of solutions. For example, different saving modes may be selected depending on whether or not some specific operation is included in the editing operation.
Specifically, in an embodiment of the present invention, the step S12, according to the editing operation, determining a saving manner corresponding to the editing operation may include:
if the editing operation comprises a preset operation, determining that a storage mode corresponding to the editing operation is rewriting storage; based on this, in step S13, the updating and saving the original file based on the determined saving mode includes: under the condition that the editing operation comprises a preset operation, the original file is entirely 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 that a storage mode corresponding to the editing operation is incremental storage; based on this, the updating and saving the original file based on the determined saving manner in step S13 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 comprises at least one of: adding password operation, removing password operation and deleting operation.
The operation of adding the password can mean encrypting the content of the file, and the password needs to be input when the file is reopened next time. The delete password operation may refer to decrypting the encrypted file content without entering a password the next time the file is reopened. A delete operation may refer to deleting any content in the file, such as deleting pages, text, pictures, annotations, and so forth.
That is, in this embodiment, if the editing operation that the original file undergoes includes any one or more of the operation of adding a password, the operation of removing a password, and the operation of deleting a password, a rewrite saving mode is adopted when the file is saved, and the original file is entirely replaced by the first new file formed after the editing operation and written into the saving address. If the original file does not include the operations of adding the password, removing the password and deleting the password in the editing operation, an incremental saving mode can be adopted, the content of the original file is reserved in the saving address, and the operation content corresponding to the editing operation is added to the original file to form a second new file.
The rewriting storage mode can recode the content of the file so as to realize the password adding operation or the password removing operation, and after the file is deleted, the content of the file is relatively reduced, so that the workload of rewriting storage is reduced.
Except for password adding operation, password releasing operation and deleting operation, the file can be saved in an incremental saving mode after other editing operations. The incremental storage mode is only to attach the newly added change after the original file content, and the incremental storage speed is higher because the newly added storage 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 thereto, and in other embodiments of the present invention, the preset operation may include more or less editing operations.
For example, in an embodiment of the present invention, the determining, according to the editing operation in step S12, a saving manner corresponding to the editing operation may include:
if the editing operation comprises a preset operation, determining that a storage mode corresponding to the editing operation is rewriting storage; based on this, the updating and saving the original file based on the determined saving manner in step S13 may include: replacing the original file with a first new file formed after the editing operation to write the original file into the 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, the updating and saving the original file based on the determined saving manner in step S13 may include: replacing the original file write-in storage address with the first file formed after the editing operation; or 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 file;
the preset operation comprises a password adding operation and/or a password removing operation.
That is to say, in this embodiment, the preset operation only includes a password adding operation and/or a password removing operation, if the editing operation that the original file undergoes includes the password adding operation and/or the password removing operation, the file is saved in a rewriting saving manner, and if the editing operation that the original file undergoes does not include the password adding operation and/or the password removing operation, what saving manner to take may be further determined according to the size of the file.
Specifically, in an embodiment of the present invention, determining, according to a comparison result between the file size of the original file and a preset threshold, a saving manner 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, determining that the storage mode corresponding to the editing operation is rewriting storage;
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 small, and it does not take too long to save the file by rewriting once. If the file size of the original file is larger than the preset threshold value, the file data volume is large, and when rewriting is more costly, an incremental storage mode can be selected for file storage, so that the file content is ensured to be correct, meanwhile, the balance is carried out between the file size and the time spent in file storage, and the file storage efficiency is effectively improved.
In the above embodiments, when selecting the file saving mode, it is detected whether the editing operation performed on the original file includes a preset operation, but the embodiments of the present invention are not limited thereto. In other embodiments of the present invention, different manners of saving may be performed according to whether the editing operation is one of the operations.
For example, in an embodiment of the present invention, the determining, according to the editing operation in step S12, a saving manner corresponding to the editing operation may specifically include:
if the editing operation is a page deleting operation, determining that a storage mode corresponding to the editing operation is rewriting storage; based on this, the updating and saving the original file based on the determined saving mode in step S13 includes: replacing the original file with a first new file formed after the editing operation to write the original file into the 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, the updating and saving the original file based on the determined saving mode in step S13 includes: and reserving the content of the original file in the saving 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 only includes a page deletion operation, the file content of the original file is greatly reduced after the page is deleted, so that a large amount of storage space is saved, and therefore, the file can be saved in a rewriting saving manner. On the contrary, if the editing operation only includes the operation of deleting the non-page, the operation of deleting the non-page only can reduce the file content of the original file by a small amount, and the saved storage space is limited, so that the file can be saved in an incremental saving mode, so as to save more file saving time.
Of course, in other embodiments of the present invention, resources such as time and space consumed for saving a file may be balanced according to various factors such as the size of the file and the editing operation, for example, a product of a space saving rate and a time saving rate may be used as an index to select a file saving mode with the highest efficiency.
