This menu command allows you to resume a partially-completed download. If a download is interrupted by a network or server error, or is cancelled, it is sometimes possible for Fetch to resume it without re-downloading the part of the file that you already have. There are a number of limitations on this feature. Fetch can only successfully resume a transfer if:
Ñ It happened in the current session. If you quit Fetch or it crashes, Fetch will lose the information it needs to resume the transfer. Note: you may close the transfer window in question without losing that information.
Ñ The file has not changed since you first tried to download it. Otherwise you will get part of one file and part of another, with unpredictable results.
Ñ The server supports the restart (REST) command, and (if the file is a text file) implements it the way that Fetch expects. Most servers support restarting transfers. When they do, they implement restarted text downloads in one of two different ways, and this can lead to missing or duplicated information in resumed text downloads. You can avoid this problem by downloading in binary mode (e.g. by clicking the Binary button in the transfer window), but that may give you a file with incorrect line endings.
Ñ The file was not inside an entire directory that you were transferring; Fetch can not resume such transfers.
Ñ It was not a StuffIt 1.5 archive. Fetch is not smart enough to resume a download if the file was a StuffIt 1.5 archive and Fetch was in the process of expanding it. Note that StuffIt 1.5 archives are quite rare (most archives are StuffIt Deluxe archives, which Fetch passes to StuffIt Expander).
If all of these conditions can be met, the Resume Download command can save a lot of time. When you choose the menu command you will be shown a list of the downloads that are eligible to be resumed. You may also select files and click the Remove button to have Fetch forget about them (this frees up the disk space taken by the partial file). To resume a transfer, click its name and then click OK (or else double-click the name). Fetch will reconnect to the appropriate server (if necessary), and attempt to complete the download. If Fetch is successful, the file can be found in the folder where it was originally being saved.
