This is probably a simple problem for someone to help with. I have been downloading using jetdownloader successfully for several months.Last week a problem occurred. After I download a file, I open the folder and instead of the winarchiver icons, there are several VLC player icons. Typically, when i see the winarchiver icons, i just click on the first one and it converts all the files into a nice VLC completed movie file. Now, with these new VLC icons, I cant figure out what to do after trying all the options available.Can someone please advise?Thank youWe would need to know what's the actual extension of the file to properly give you advice.My best guess is that you downloaded files that have been binary split with extension 001, 002 and so on. To join them, you need a software like hjsplit or ffsj or you could simply open a command line window, navigate to the folder where your files are(by using cd and typing the full path) and type this:Code:COPY /B /V Name_of_your_file_with_the_first_number_of_the_extension??New_name_of_the_files.extention_of_videoFor exampleCode:COPY /B /V DVDES-123.0?? DVDES-123.aviI prefer that method since you can verify if the files were joined properly which most app skip because it takes longer and they can't claim they're the fastest, but it might be a bit complicated for someone who never used command line.
