Searching the source for duplicates does not produce any. This most usually happens with very large uploads (3000 or more files) The timestamp on the source file is always older than the destination one. My solution has been to set ""overwrite if source is newer which leaves the original transfer alone but the problem for me is it often takes hours to do this and sometimes it is next day before I find the message. FZ version 1.10.11 also shows occasional failed transfers :Could not start transfer." Bug report closed normal FileZilla Client outdated overwrite existing file Windows seven Professional
