Steam reserves (allocates) the space required for the download in order to optimize disk usage by trying to minimize disk/file fragmentation and of course it checks the available disk space before the actual download.
Basically, the downloads get stuck in a pause-unpause loop, where no data is ever downloaded. The downloads just keep starting and stopping. I had my Tesla Effect download sitting at 13.5GB. After relaunching Steam, 'preallocating' GTA 5 should take about 5 minutes to finish before beginning the 'unpacking' and 'busy writing to disk' which will take the longest because you are decrypting ~60GBs. Just got stuck with gta 5 social club launcher, i have made a new account on social club website & also activate the game on the site. Do you have enough disk space for the game? If you do, then just restart Steam, I guess. Restarted Steam a couple of times, also tried the suggestion to delete the EA and start fresh on the download. Loren on the Art of MATLAB.

Jeremy works on the Code Analyzer and will be discussing when preallocating MATLAB arrays is useful and when it should be avoided. Anyone else have this problem? Any known solution?
This helps increasing the game's performance (like already stated in the comment by Ross Ridge) and saves valuable time, because the download won't start when the allocation fails (e.g. not enough space on your disk) and the files are written to the disk faster, because it already 'knows' where to put them. Allocating each file separately can cause some delay on slower disks especially with downloads of several 1000s of files (download - wait - download - wait, instead of download - download - download).

In addition to @dly's answer, preallocation is necessary when downloading files, regardless of optimization or performance.
By preallocating files, the OS already knows how much space will be occupied. If any other application attempts to fill that space, the OS will report that there is not enough disk space available.
This is especially important, because you don't want to spend hours downloading a file, just to realize that you no longer have enough space for it, just because another app was also writing. It gets even worse if that other app is also lacking space, just because your download occupied too much.

How can be select seq.nextVal from dual can be null ? Because that's what internally happens in updateAndSelectSequence() method.
I have also enabled ((AbstractSession)session).setIsConcurrent(true); Bollywood movie download. for improving performance, in my SessionCustomizer class.Does this property has to do something with this ?
