Embodiment
The specific embodiment of the invention that below provides is used for content of the present invention is done more specific description.Embodiments of the invention mainly are based on one dual operating systems are installed, it is the computing machine of (SuSE) Linux OS and Windows operating system, and adopt linux kernel to the limited support of NTFS and the mature technology under the (SuSE) Linux OS, realize purpose of the present invention in conjunction with existing virtual partition technology.The virtual technology that is adopted in the present embodiment can be loop dummy block will equipment and technology (also claiming the virtual partition technology), described loop virtual partition technology is to use the loop technology that a file is invented a block device under Linux, thereby this document can be loaded as the next subregion of Linux, and then can in this document, set up, delete, rewrite file and catalogue.Combination by above-mentioned technology has realized the expansion of Linux operation to the support function of NTFS, thereby reaches the ability of visiting the NTFS data under (SuSE) Linux OS fully, and no longer only limits to only the NTFS data be read the function of modification.Because under the Windows system, the opening of loop virtual partition technology makes its instrument that is easy to be developed out read-write loop file, thereby be implemented in the purpose of the data that reading and writing Linux stores down under the Windows environment.Clearly, the combination of above-mentioned technology has overcome the limitation of checking the limited access of file under the NTFS form in the existing (SuSE) Linux OS, has realized utilizing under Windows operating system and the (SuSE) Linux OS data sharing of NTFS subregion.
Hereinafter with reference to accompanying drawing specific embodiments of the invention are done more detailed description.
Fig. 1 is the computing machine that above-mentioned dual operating systems is housed, under (SuSE) Linux OS with the schematic flow sheet of the exchanges data of the NTFS subregion of Windows operating system.
At first, under Windows operating system, carry out following step:
Create null object file step: the file destination of a certain NTFS partition creating under Windows operating system, and this file destination formatd processing, make it become a null object file, described null object file is meant that file data all is the file of " 0 ".Above-mentioned format is handled master and is judged that whether this file destination is empty file and to not carrying out all " 0 " processing clearly for empty file destination and file destination that should sky is processed into the needed data layout of system (the needed data layout of the system among the embodiment is often referred to and is the discernible data layout of following virtual partition).The big I of this null object file is set according to the actual demand of application program, and the null object number of files of being created also can be created one or more according to actual needs.
The method of above-mentioned establishment null object file can adopt a driver to create, for example utilize the method for looptool to create, exploitation such driver (Looptool) under Windows operating system, this driver has following function: can create an empty file and this empty file format analysis processing is become the needed data layout of system, the empty file file of being created is used under (SuSE) Linux OS its form with the loop file being loaded, thereby can in this subregion, read, write, increase, delete, change catalogue and file, and be not subjected to linux kernel can't rewrite the restriction of NTFS file size etc. at present.And under the Windows system, a loop file mount can be become virtual partition, make window application with of the form read-write of this loop file, and needn't be concerned about its storage inside mode with subregion.
Form the swap file step: after the file destination process of being created was formatted into to the null object file, system was a swap file with this null object file designation.
Then, enter (SuSE) Linux OS, can carry out following step when computing machine switches:
Loading swap file is virtual unit or virtual partition step: utilize the support of checking the NTFS subregion in this (SuSE) Linux OS, above-mentioned swap file is loaded as a virtual unit or a subregion.Here, we can adopt existing loop virtual partition technology with this load document by order as: mount-oloop test.img/mnt/tmp, (here, the name of swap file is called test.img) is mapped as a virtual partition.In fact, with swap file virtual be that a partitioned method is not limited only to loop virtual partition technology, can also adopt self-defining logical file to be divided into partitioned method or other method, substitute loop technology etc., enumerate no longer one by one here as adopting the ISO file.Because linux kernel has been realized the rewriting operation to file in the NTFS subregion, and the size of the loop document swap file (test.img file) that can not change (this also just meets the restriction of present linux kernel version 2.6.9-1.667 to the NTFS operation), and support the operation of all file directory, therefore at this moment (SuSE) Linux OS can realize increasing completely, delete, changing etc. operations such as file and catalogue to the virtual partition that is loaded.
The complete accessing step of the upper level applications of (SuSE) Linux OS: after completing successfully above-mentioned loading swap file and being virtual unit or virtual partition step, the virtual unit or the partition data of the loading that the upper level applications of (SuSE) Linux OS is can direct read above-mentioned, thereby reach visit fully, and do not need to consider whether this equipment or subregion are the NTFS structure.
Unloading virtual unit or subregion step: after the upper level applications of (SuSE) Linux OS is visited fully, unload above-mentioned virtual unit or subregion, can use loop tool to unload this virtual partition here.
At last, enter under the Windows operating system, can carry out following steps when computing machine switches again:
Loading swap file is virtual unit or subregion step, the visit fully of the upper level applications of Windows operating system and unloading virtual unit or subregion step, and step performed under these steps and the (SuSE) Linux OS is roughly the same.
Loading swap file is virtual unit or subregion step: the swap file in the above-mentioned formation swap file step is loaded as a virtual unit or a subregion.Can utilize the above-mentioned driver of developing to realize specific to swap file being loaded as virtual unit or partitioned method, be a subregion under the Windows operating system with this swap file carry.
The complete accessing step of the upper level applications of Windows operating system: complete successfully above-mentioned swap file be loaded as virtual unit or subregion rapid after, the upper level applications of Windows operating system can directly read the file data that the application program of (SuSE) Linux OS is imported into, also can write file data in it.
Unloading virtual unit or subregion step: after the upper level applications of Windows operating system is visited fully, unload above-mentioned virtual unit or subregion, can use loop tool to unload this virtual partition here.
In addition, among the embodiment 1, computing machine is to switch earlier to enter (SuSE) Linux OS to load swap file be virtual unit or virtual partition step, operations such as complete accessing step of upper level applications and unloading subregion step still switching earlier enter the corresponding operation of Windows operating system execution, also can set arbitrarily, not do strict restriction here according to concrete actual demand.
The loop virtual partition technology that adopts described in the above embodiment also can adopt and self-defining logical file is divided into partitioned method or additive method, as long as can be that partitioned method can be used promptly, substitute the loop technology as adopting the ISO file with a File mapping.
Employing driver (Loop tool) described in the establishment null object file step among the above embodiment under Windows operating system is made the method for empty file and also can be used other instruments that can generate empty file to replace, as using virtual drive software creation empty file such as WinISO.
Loading swap file among the above embodiment under Windows operating system by in virtual unit or the subregion step employing drive method that (Loop tool) load swap file and also can use other can discern and load this swap file to become that partitioned method realizes under the Windows, as except adopting the ISO file, can adopt virtual drive to create the technology of file.
Be illustrated in figure 2 as the device that the present invention is implemented in the NTFS partition data exchange under (SuSE) Linux OS and the Windows operating system.
This device mainly comprises creates empty file unit and virtual unit, and wherein said establishment empty file unit is used for creating one or more empty files on the NTFS of Windows operating system subregion.
Described virtual unit is by comprising a loading unit and a unloading unit, as shown in the figure, the virtual unit of the W-under Windows operating system, W-loading unit and W-unloading unit, and the virtual unit of the L-under (SuSE) Linux OS, L-loading unit and L-unloading unit.
The empty file that described loading unit utilizes virtual minute technology that establishment empty file unit is created is loaded as one or more virtual units or virtual partition under system separately.Can the upper level applications of each system under the system separately be visited completely through the virtual unit after loading or subregion, promptly can realize processing such as file and catalogue are set up, delete and rewritten completely to file.Virtual unit or the subregion of the technology that described unloading unit is used to utilize virtual partition after with the upper level applications visit of each system unloads.
Wherein said establishment empty file unit further comprises creates file unit and formatting unit (not shown), described formatting unit is to format processing to creating the file of creating in the file unit, makes it become the needed data layout of empty file and system.
In the L-loading unit, the file load that (SuSE) Linux OS can use equipment and technologies such as loop will create in the empty file unit is the L-virtual partition.In the W-loading unit, need to utilize a driver of exploitation in advance to come above-mentioned file is loaded as the W-virtual partition in the Windows operating system.This driver can use Loop tool instrument to develop, program after the exploitation has can create an empty file, the empty file file of being created is used under (SuSE) Linux OS its form with the loop file being loaded, thereby can in this subregion, read, write, increase, delete, change catalogue and file, and be not subjected to linux kernel can't rewrite the restriction of NTFS file size etc. at present, and under the Windows system, a loop file mount can be become virtual partition, make window application with of the form read-write of this loop file, and needn't be concerned about the function of its storage inside mode with subregion.
Here need to prove, in L-loading unit under the L-of (SuSE) Linux OS loading unit and Windows operating system, which swap file will be system separately will select load and how select needed swap file, all not need to do special qualification at this.Each system can set the swap file of selecting required loading according to concrete actual needs, generally can consider to select the swap file after another system has unloaded.Method selected also can freely be set, for example can set an identifier to the file that returns after the (SuSE) Linux OS unloading, give with Windows operating system unloading back backspace file and give another different identifier, different like this operating system can be carried out loading processing according to the file of selecting to have party identifier, so that can visit the file data that the application program of another system operation system is imported into.Because having the setting identification symbol to be set at above-mentioned two systems according to concrete needs, empty swap file all can directly not load or only specify one of them system to load.
In sum, the method and apparatus of the NTFS partition data of (SuSE) Linux OS of the present invention and Windows operating system exchange has solved under the Linux problem to the limited access of NTFS subregion to a certain extent, and making the data resource of Windows and Linux exchange visits becomes possibility.Simultaneously, this method is carried out on bottom layer driving, no matter the upper strata is existing is that window application or Linux application program need not to carry out code revision, can be convenient to use this method and carry out Windows and Linux based on the data sharing of NTFS, has simplified the use difficulty greatly.
