FSO means FileSystemObject, which is the file system object. The FSO object model is included in the Scripting type library (Scrrun.Dll). It also contains five objects: Drive, Folder, File, FileSystemObject and TextStream, which is very convenient for operating files and folders.
FSO file (File) object properties
DateCreated returns the creation date and time of the folder
DateLastAccessed returns the date and time the file was last accessed
DateLastModified returns the date and time the file was last modified
Drive returns the Drive object of the drive where the file is located.
Name sets or returns the name of the file
ParentFolder returns the Folder object of the file's parent folder
Path returns the absolute path of the file, long file names can be used
ShortName returns the DOS-style 8.3 form of the file name.
ShortPath returns a DOS-style 8.3-style absolute path to a file
Size returns the size of the file (bytes)
Type If possible, returns a string describing the file type.
FSO file (File) object methods
FSO file object method usage
CopyFile copies one or more files to a new path
CreateTextFile creates a file and returns a TextStream object
DeleteFile deletes a file
OpenTextFile opens a file and returns a TextStream object for reading or appending
Rename the file:
Copy the code code as follows:
Function reName(sourceName,destName)
dim oFso,oFile
set oFso=server.createobject("Scripting.FileSystemObject")
set oFile=oFso.getFile(Server.mappath(sourceName))
oFile.Name=destName
Set oFso=Nothing
Set oFile=Nothing
End Function
Delete files:
Copy the code code as follows:
Function FSOdel(fileName)
dim fso,f
set fso = server.CreateObject("scripting.filesystemobject")
f=server.MapPath(fileName)
if fso.FileExists(f) then
fso.DeleteFile f,true
end if
set f = nothing
set fso = nothing
End Function
Replace a string in a file:
Copy the code code as follows:
Function FSOreplace(fileName,Target,repString)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(fileName),1,True)
FiletempData = objCountFile.ReadAll
objCountFile.Close
FiletempData=Replace(FiletempData,Target,repString)
Set objCountFile=objFSO.CreateTextFile(Server.MapPath(fileName),True)
objCountFile.Write FiletempData
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End Function
