In addition:
There might be other reason why the system is not accepting your upload regardless of size ...
Name is not valid nor the file is damage and corrupted ...
ex: [allowed and valid] file
Screenshot_3.jpg

However you can do the ff:

Try to rename the file w/o any symbol
[copy the original name first before doing this in case of error]

or rename/delete [.iso] extension file that is accepted [zip file/rar file are no longer allowed]

IMPORTANT !!! ... remember this is a critical task so make a copy/back up first in case there will be an error from renaming ...

and make a note from the original file [name] to avoid any other confusion ...

If the system rejected this process ...

make a folder and insert the original .iso file/data [name] and try again ...

Lastly try to extract the file [this works and common issues] and do not altered or renaming [VIDEO_TS] folder ...
Then you can submit ...

Is there something special to consider when uploading a DVD?
