Very strange. Are you using the 32 bit or the 64 bit version?

I am not at my laptop ATM, I will check once I have a chance.

@FBiDev it seems I did not enable support for files larger than 4GB. Can you please test if these new versions (both 32 bit and 64 bit) work? windows_bin_x86.zip windows_bin_x86_64.zip

Hi! Now both exe 32-64 work to apply Patch!!! But to create a patch, dont work, he produce a xdelta with more than 1gb. and the original xdelta have only 30mb.

[marco-calautti]

This I think it depends on the window size. What value are you using for the -B flag when using the command line?

[FBiDev]

in command line fails to create a patch with files greater than 4GB too, only apply if you already have a patch, i tested with a file 3.3Gb and works great, produce a xdelta with 11mb, equal your program, now with a .ISO with 4.03Gb he create xdelta very large

.\xdelta3.exe -B 134217728 -W 8388608 -v -f -e -s 'Original.iso' 'Modified.iso' 'delta.xdelta'

A Linux user say me that he can create a pach in linux normal using this command line:

xdelta3 -B 4333170688 -W 67108864 -vs "Original.iso" "Modified.iso" "Patch.xdelta3"

for me in Windows, not work, produce a large xdelta file

You are probably using a different version of xdelta3. With version 3.1.0 you should get a small patch as expected. As for Delta Patcher, I just need to enable larger window/block sizes.

With your program i set: lzma level 5 1024 Window Size and all files work great wit less 4gb, with 4gb, fails to create small files

i discovered this issue open in xdelta github, that is from >4Gb files in windows https://github.com/jmacd/xdelta/issues/127

[marco-calautti]

Indeed, there is a bug in the xdelta library, that never got fixed. I don't know if that is the same you are referring to, but I just fixed the bug I found at least. I will test on Windows whether things now work as expected.
