- Does the directory structure of the source dirs need to be preserved? i.e. when you want to "pick the zipped files from each sub-directory which are placed in SFTP server and move to different directory" as you said, will the files


##From SFTP location, we just need to pick up the zipped files from each sub-directory and move it to on different location as /other_place/zipped1.zip and other_place/zipped2.zip which is on unix environment.

If the latter, what should be done about identical filenames?

##This scenario is not applicable here as the zipped files will be differently named by the source system. I would get more info regarding this situation.

- What should be done about different versions? i.e. suppose there is a file

##If the same file is available in target location, then use the file in the source directorY AND leave the file in the target directory. The files which we are moving to is intermediate layer so the zipped will be completely moved from the target location to another server.

So once we have moved the zipped files to target location, then we need to check if each file within zipped file is not 0 kb and if we find a 0kb file then raise an email with some content.
