'调用方法: Set Obj=New FSOControl
'所有路径必须为绝对路径,请采用Server.MapPath方法转换路径后再定义变量
'------ FileRun ---------------------------------------
'
'必选参数:
'FilePath ------ 处理文件路径
'
'可选参数:
'FileAllowType ------ 处理文件允许的类型,定义方法例: gif|jpg|png|txt
'FileNewDir ------ 文件处理后保存到的目录
'FileNewName ------ 新文件名前缀,请不要添加后缀, 例: sample.txt 则为 sample
'CoverPr ------ 是否覆盖已有的文件 0为否 1为是 默认为1
'deletePr ------ 是否删除原文件 0为否 1为是 默认为1
'---------------------------------------------------------

'------ UpDir(path) 取path的父目录
'path可为文件,也可为目录

'------ GetPrefixName(path) 取文件名前缀
'path必须为文件,可为完整路径,也可是单独文件名

'------ GetFileName(path) 取文件名
'path必须为文件,可为完整路径,也可是单独文件名

'------ GetExtensionName(path) 取文件名后缀,不包含"."
'path必须为文件,可为完整路径,也可是单独文件名

'------ FileIs(path) path是否为一文件
'如为,返回 true 否则返回 false
'------ FolderCreat(Path)
'------ Folderdelete(Path,FileIF)
