Title: .part .met temp files not cleared after download complete ?
Post by: mrechte on April 30, 2005, 07:49:20 AM

Hi,

When checking my temp directory, I noticed that there are .met files thare are bigger than the biggest file I am currently downloading. I wonder whether that directory is properly cleaned.

How would I know that a file is no longer used, and therefore  can manually be deleted ?

Thanks

click in the amule-gui on your downloads, rightclikc and in the middle you can read what part file it is, at the preview

or select file details from that menu, its also written there

Thanks for your help

I just realised that each current download creates one .met file of nearly (I say nearly because in some cases it is less) the file size, even if a small portion of it is downloaded. This is is a big waist of hard disk space !

Regards

Marc.

no its not a big waste...

hte file size is most often completly allocated after you dl 9,98 MB of the whole file (which is one part)

so then the amule creates a container where this downloaded part goes into, and it starts to download the next part,
but since you dont start usually with part 1 and then 2 and so on, all the file size is used, to put the actuall parts already where they belong.

other sharing systems where teh file size increases while downloading, start at teh beginning, which makes them slow, since in ed2k you can download 2 different parts independently. every mule programm will do it this way

###.part is the file name where your downloaded data goes. ###.part.met is the description of the .part file, and should be only some kb.

When aMule downloads a piece of data, opens the .part file, seeks to the position where this piece belongs to, and writes it there. This will result in the file size enlarged to the position of the last downloaded data piece. Actually on file systems which support sparse files, disk space is only allocated for real downloaded data, not for empty parts.

Example: say you start downloading a 800Mb file. Say, that aMule first downloads 180kb from the middle of the file. When it is saved, the .part file size will be 400Mb, but only 180kb disk space is allocated.
