see at 218 package

screenshoot JD







but when i try to reset download link, JD says perfect size, i mean same as real size on PC




on 218 package bytes loaded only 21,24MB but when downloaded is complete , JD show correct bytes loaded like package 201 ,202,203 , see picture




not only package 218 problem, 219 package also have same problem, this is not first time JD wrong calculate loaded size ,i got this problem 1 year ago when i using JD2

How many chunks are you downloading with ??

soon as you download with chunks it pre-locates.

for example chunks 20 at 1GiB total filesize
chunks value - 1 = 19 total chunks of preallcoation
1GiB/20 = 50MiB * 19 = 950MiB

preallocating will require harddrive to store that data, it does this about that the 8MiB downloaded mark, after 8MiB and your harddrives are not fast it tends to have freezing/locking behaviour, whilst the allocation completes. If you disable to click stop (square on toolbar) it wont respond until preallocation completes. Also if you're saving across the network it can be slow! Or even in VM can be slow!

im only using 2 chunk because free user uptobox only support 2 chunk at 1 link, my total bandwidth is 350 kbps , kilo byte per second

[raztoki]

so it needs to pre-allocate ~half of the download with 2 chunks (assuming the server supports chunk ranging) and the last chunk range expands as downloads.

If your downloads are failing for up2box I assume they might be effected be same issue.

when i restart jd, nothing change
just suggestion ,better if each jd start, jd check again bytes loaded on pc

[raztoki]

We check if file exists on disk, and if its the same as we left it we resume

Bytes loaded on disk means jack squat, because preallocation is just full of empty data. This is why you can not resume data from JDownloader with another download program (outside one that does checksumming like classic p2p (bittorrent for example)).

[thecupu]

do you mean 719MB just empty data ? the real size is 21Mb ?

file size 1.39 GB on uptobox
okay will try with download again, if only 21 MB , i need 1,3 GB to complete download, but when i just need 600MB to complete ,i think there is problem in your JD sir

[raztoki]

Assuming jdownloader shutdown correctly, yes that is accurate.

[thecupu]

but when i resume download that 218 package file on my pc 719MB also increase
are you sure sir ?

[thecupu]

file size 1,24 on uptobox
i try with 224 package , because on my pc, i already download 900MB and i only need 300MB to complete

[tony2long]

The percentage shows that 637 MiB is 50% so you still need 637 MiB more.

[raztoki]

you are downloading 224 file, and YES I am sure (no need to question my answer 100 times). Not sure how many times I have to say it! But here goes!!

The last chunk expands as you download. So if you download with 2 chunks and now downloaded 50% total, we can assume both chunks are ~25% complete.
1.24GiB/2= 0.62 . so chunk - starts at 0-0.62GiB all this is preallcoated, chunk 2 starts at 0.62-END this expands as it downloads. So total used space at this time (50% total download) = 0.62+(1.24/4) = 0.93GiB. so roughly speaking it matches your screen shot of 986 586 KB

[thecupu]

sir , you still dont answer my question
do you mean 719MB just empty data ? the real size is 21Mb ?


EDITED , the bug cause when JD force shutdown

answered the question multiple times and explained how it worked. Thread locked.
