如何检查FTP服务器中其他文件夹中是否存在文件 [英] How To Check If a File Exists In FTP Server in different folder

问题描述

我有两个变量，它们包含ftp中文件的路径:

第一个名为  file1的变量包含该值:ds/product/Jan/09122016_product.csv
第二个名为file2的变量包含该值:ds/subproduct/Jan/09122016_subproduct.csv
第三个名为  file3的变量包含该值:ds/category/Jan/09122016_category.csv

每个文件位于不同的文件夹中，但位于同一服务器上

我想要的是检查ftp中是否存在3个文件

谢谢
