A Question When AutoSync

[中目黑善树]

Hi,

I am using FolderSync to syncing my file between my phone and computer by SMB.

But I meet a question. When my computer already had some files, called 1234.jpg, FolderSync will sync the same files to computer, called 1234_yyyymmdd_hhmmss.jpg(like 1234_20150503_180808.jpg). In fact they are same, so I will have double files in my computer. That's too silly.

So I come to here and ask how to resolve this question. Using MD5 checking or something?

Hope to reply.Thanks.

And please forgive my poor English.
