Let's take a look at how to use fso for file operations. Fso is the core of file operations in vbs. As a hacker, No matter what language you are learning, you should be familiar with file operations, so please study carefully.
Let's not talk nonsense. Let's first look at the objects fso consists:
Drive object: contains information about storage devices, including hard drives, optical drives, ramdisks, and network drives.
Drives collection: provides a list of physical and logical drives
File object: Check and process files
Files set: provides a list of files in a folder.
Folder object: Check and process folders
Folders set: provides a list of folder subfolders.
Textstream object: read/write text files
Look at the fso method: because there are many methods, I will not write down each function. If you do not understand it, check msdn on your own. Don't say no.
Buw.path: adds the file path information to the existing file path.
Copyfile
Copyfolder
Createfolder
Createtextfile
Deletefile
Deletefolder
Dreveexits
Fileexits
Folderexists
Getabsolutepathname: returns the absolute path of a folder or file.
Getbasename: returns the basic path of a file or folder.
Getdrive: returns a dreve object.
Getdrivename: returns the name of a drive.
Getextensionname: returns the extension.
Getfile: returns a file object.
Getfilename: returns the name of the file in the folder.
Getfolder
Getparentfoldername: returns the parent folder of a folder.
Getspecialfolder: returns the object pointer to a special folder.
Gettempname: returns the name of a randomly generated file or folder that can be used by createtextfile.
Movefile
Movefolder
Opentextfile
Well, I think you have understood more than half of it here. Maybe you don't need to talk about it later. The script is so simple. Heheh, let's continue.
1. Use fso
Because fso is not part of wsh, we need to build its model.
For example, set fs = wscript. createobject ("scripting. filesystemobject ")
In this way, the fso model is created. It would be easy to release, set fs = nothing
2. Use folders
Create:
Before creation, check whether the program exists.
* *************************** Createfolder. vbs *****************************
Dim fs, s
Set fs = wscript. createobject ("scripting. filesystemobject ")
If (fs. folderexists ("c: \ temp") then
S = "is available"
Else
S = "not exist"
Set foldr = fs. createfolder ("c: \ temp ")
End if
Delete, copy, and move
Delete:
Set fs = wscript. createobject ("scripting. filesystemobject ")
Fs. deletefolder ("c: \ windows ")
Copy:
Set fs = wscript. createobject ("scripting. filesystemobject ")
Fs. copyfolder "c: \ data" "d: \ data"
NOTE: If both c: \ data and d: \ data exist at this time, an error will occur and the replication will stop. If you want to forcibly overwrite data, use fs. copyfolder "c: \ data" "d: \ data", true
Mobile
Set fs = wscript. createobject ("scripting. filesystemobject ")
Fs. movefolder "c: \ data" "d: \ data"
Wildcard characters:
You can use the wildcard for convenient operations:
For example, fs. movefolder: c: \ data \ te * "," d: \ working"
I didn't use "\" at the end of the target path. That is to say, I didn't write it like this:
Fs. movefolder: c: \ data \ te * "," d: \ working \"
If the d: \ working directory does not exist, windows will not automatically create this directory for us.
Another point is that none of the above mentioned involves the folder object. We are all using the method provided by fso. Of course, the folder can be used in the same way:
Set fs = wscript. createobject ("scripting. filesystemobject ")
Set f = fs. getfolder ("c: \ data ")
F. delete 'delete. Sub-directories are also deleted.
F. copy "d: \ working", true' copy to d: \ working
F. move: "d: \ temp" 'move to d: \ temp
Special folder
It generally refers to the System Folder \ windows \ system32, Temporary Folder, windows Folder
Let's take a look at the following: we use environment variables to get the windows directory. We will detail the environment variables later. If I forget it, please remind me
Set fs = wscript. createobject ("scripting. filesystemobject ")
Set wshshell = wscript. createobject ("wscript. shell ")
Osdir = wshshell. expandenvironmentstrings ("% systemroot % ")
Set f = fs. getfolder (osdir)
Wscript. echo f
Of course, there is also a simple way to use getspecialfolder ()
This method uses three values:
0 indicates the windows folder. The constant is windowsfolder.
1. System Folder. The constant is systemfolder.
2 temporary directory, constant temporaryfolder
See the following example:
* ********************************* Getspecialfolder **** ***********************
Set fs = wscript. createobject ("scripting. filesystemobject ")
Set wfolder = fs. getspecialfolder (0) 'Return to the windows directory
Set wfolder = fs. getspecialfolder (1) 'returns system32 \
Set wfolder = fs. getspecialfolder (2 )'
3. Use Files
Use file attributes:
I did not mention the folder attributes. You can refer to the file attributes in the opposite way.
Common file attributes are:
Normal 0
Readonly 1
Hideen 2
System 4
Set fs = wscript. createobject ("scripting. filesystemobject ")
Set f = fs. gerfile ("d: \ index.txt ")
F. attributes = f. attributes + 1
The file attributes of d: \ index.txt are unknown, so unpredictable results may occur. If the file attribute is 0, it will become 1. Therefore, it is best to query the attribute before changing it.
Create
Before creating a folder, check whether the file exists.
* **************************** File. vbs **********************************
Set fs = wscript. createobject ("scripting. filesystemobject ")
If fs. fileexists ("c: \ asd.txt") then
S = "available"
Else
S = not exist"
Set f = fs. createtextfile ("c: \ asd.txt ")
End if
Of course, we can also use set f = fs. createtextfile ("c: \ asd.txt", true)
To forcibly overwrite existing files.
Copy and move deleted files
Like folders, we can use both the fso method and the file object.
Set fs = wscript. createobject ("scripting. filesystemobject ")
Fs. copyfile "c: \ asd.txt", "d: \ 1 \ asd.txt", and "true" copy the file. If the file already exists, it is forcibly overwritten.
Fs. movefile "c: \ asd.txt", "d: \" 'Move
Fs. deletefile "c: \ asd.txt" 'Delete
Now, in the next chapter, we will learn how to read and write files. File Reading and Writing is a very important part of file systems, especially hacker programming. Today there may be many typing errors, when you look at it carefully, you don't know much about msdn. To improve the performance, you only need to be on your own. Others cannot help you.
