Preallocate files

[i4u1]

I guess for preallocation files in latest build used SetFileValidData instead of SetEndOfFile which is wrong.

anyone offering a fix for this since i seriously dont enjoy finding out i left my comp for two weeks and end up with no space because the program didnt even bother pre-allocating it.

Hoping to see it sooner or later. Hope soon

Disable diskio.sparse_files.

You find that option in the Advanced screen. http://utorrent.com/faq.php#What_do_all_those_settings_in_Advanced_do.3F

Stop, sparse files have nothing to do with "Pre-allocate all files". Preallocation means reserving space - it worked correctly in 1.7 but in 1.8 it doesn't allocate/reserve any amount of data.

I suggest: CreateFile, SetFilePointer with filesize from FILE_BEGIN, then SetEndOfFile

Instead of as i said SetFileValidData.

Or just remove this option cuz it doesn't do what it should - no reserving space.

What the difference in using sparse files and not when no preallocation is done?

[thelittlefire]

Sparse Files is default ON in 1.8 BECAUSE it doesn't actually allocate the space on disk... decreasing disk load. It tells the OS, i.e. to alert Quotas and other things, but it will not actually use that space, say if you have a 60 GB torrent.

[i4u1]

Then the space may be occupied by something else that will lead to fail downloading the torrent in 60GiB. Again - sparse files aren't preallocation of files.

Sparse files overrides pre-allocate (though it wasn't supposed to in this release).

[sdliddo]

well disabling that seems to have fixed it somehow.
