# Downloads

This page contains the configuration options for where DC++ will place complete and incomplete downloads, options that control the maximum simultaneous downloads, and information on the public hub list that DC++ will use.

## Directories

Default download directory
  After a download is complete, DC++ tries to move your just finished file to this directory. It defaults to the "Downloads\" subdirectory under where the DC++ executable is located. The directory will be automatically created if needed.
  Make sure you have enough disk space for your downloads, have write access to the directory and have an appropriate file system if you download large files (note that maximum possible size for a file on a FAT32 volume is 4 GiB).
  If the target volume runs out of space, DC++ will keep your downloaded files in the Unfinished Downloads Directory having renamed them to their original filename.
Unfinished downloads directory
  All incomplete downloads will be stored in this directory. If you leave it empty, temporary downloads will be stored in the "Incomplete\" subdirectory under where the DC++ executable is located. The directory will be automatically created if needed.
  Make sure you have enough disk space for your unfinished downloads, have write access to the directory and have an appropriate file system if you download large files (note that maximum possible size for a file on a FAT32 volume is 4 GiB). From version 0.700 on of DC++, the antifragmentation method must always be used for segmented downloads to work correctly. Hence DC++ tries to reserve the full space needed for the file when starting the download. In case of an error (eg. when the drive that holds your Unfinished Downloads runs out of space), you will get an error message going like "Not enough space on the disk" even if your target drive does have enough free space! Incomplete file names follow the following rule: <filename>.<ext>.<TTH>.dctmp.
  You can use the %[targetdrive] variable in order to have unfinished download directories in all of your target drives. This way, unfinished download directories will be distributed amongst all of your drives, resulting in a smaller chance of runnig out of disk space.
  Example: when %[targetdrive]DCUnfinished\ is set as the unfinished downloads directory, DC++ creates incomplete files in E:\DCUnfinished\ when you download to any target folder located on drive E: and so on...
  The %[targetdrive] variable is also useful if you often download larger files to a drive other than the one that contains your usual unfinished directory. At the end of a successful download, moving a large file from the unfinished folder to its target can be very time and resource consuming, especially when moving files to another partition of the same physical drive.

## Limits

These settings are to avoid overloading your internet connection with a large number of simulatenous downloads. However, for both values listed below, certain conditions can result in the limits not being obeyed. Specifically, up to 3 files that are set to the 'highest' priority can be transferred while other downloads are going. File lists and small files (64 kibibytes or smaller) are queued with 'highest' as their priority. When either of the limits are hit, DC++ shows "All download slots taken" next to each source in the status column of the Connections tab.

Maximum simultaneous downloads (0 = infinite)
  This limits the number of simultaneous downloads. A value of 0 means no limit. (default: 3)
No new downloads if speed exceeds (KiB/s, 0 = disable)
  This is another method of limiting simultaneous downloads, designed to prevent new downloads if your existing downloads exceed a specific threshold. It's measured in kibibytes per second, and a value of zero will disable this limit.
  Note; because of changing download speeds, this is not 100% accurate...
