I'm using FDM for the first time. Before I only used the browser's own download manager.
I'd like to know if it's possible to configure FDM for the following:
1. Download files for the first time;
2. Once 1. is complete, then the next time, when redownloading the same files, FDM creates a backup of the previously downloaded files, by renaming them to something like somefile.txt.fdm;
3. Once 2. is complete, then it checks the URL status;
3.3.1. If the URL status is OK, then it downloads the file;
3.3.2. If the URL status is not OK, then it renames the somefile.txt.fdm back to somefile.txt;
4. FDM should only download the new file, if there's a new version of the file in the server; otherwise it should keep the previously downloaded file.
Is it possible to configure it this way? If not, would you be willing to implement this in a future version?
