Deluge Forum

Hello, all. This is my first post and I'd like to thank the creators of Deluge for making a good alternative to that adfest uTorrent, but onto the question.

I've downloaded three .iso files of two Linux distros. Linux Mint's 16 32bit and 64 bit, and Ubuntu's 32bit ISO. When I attempt to mount or open the files, it tells me

"[Window Title]
Couldn’t Mount File

[Content]
Sorry, there was a problem mounting the file.

[OK]"

When I copy and paste the ISO in the same directory, it's fine and works no problem, but the original still gives the error. I've checked the permissions and I own the file and have read/write permissions for it. This is no big issue, as I can always get past it by copying but I'd like to report it anyway.

I am not sure how this is a Deluge issue if copies of the files are fine.

Hey, dunno if you'll see this, but think I've figured this issue out.

The problem is that Windows 8's ISO mounting software doesn't support sparse files. Deluge, at least in its current version, creates sparse files when full file allocation is selected in options. The solution is either to use compact allocation, which allocates space files as they download, or rebuild deluge with sparse allocation disabled: http://forum.deluge-torrent.org/viewtop ... =8&t=27725

This is why copying/pasting the ISO fixes the issue--you've allocated new, non-sparse space. If you right-click the ISOs in question and hit details, you'll notice under attributes the sparse files will have a P. Your copied and pasted ISOs will not.
