Downloading large files in parts

Hello,

From time to time I download large files with a very slow connection. Sometimes the downloads fail after reaching a specific percentage. So can I download in parts? Or what do other people do in situations like mine?

My 'proper' solution would be to find and fix what causes the problem, but these things might work as work around:

1. Use split ( man split–split a file into pieces). It seems to be installed on most Unix systems.

2. Split the file via dd (dd if =input filename of=file_part0skip-0 bs=500MB).( repeat with skip =1 and a different file name).

3. Use a program which can resume downloading. FTP wold work (but eww. Plain text passwords, separate control and data connection which do not play nice with most firewalls).

4. Cheat and move the file to a web directory Most browsers supports resuming a download.

If you need to download a big file, I don’t think it’s possible to download only part of it and leave the other part later for downloading. But if you have a very slow internet connection and you need to download big files, it will help if you use a download manager like IDM or Internet Download Manager.

When you use a download manager like IDM, the application splits the file to be downloaded in smaller chunks then downloads them simultaneously. This allows the program to download the file much faster because the small chunks are easily downloaded. To try a download manager, download the trial version of Internet Download Manager. It works as full featured for 30 days.

The latest version at the moment supports Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8.x, and Windows 10. Another alternative is Free Download Manager.
