the first thing that you have said... refer to the name of the file? so i just need to rename they all?
yes, but not all files - only those that have filenames that are illegal under networking rules.
In the browser you would get an error message with some letters replaced by %-numbers, like spaces that are replaced by %20. Each of those cases is a letter that will NOT work - the browser needs to replace them in the error messsage because it has no way of handling the wrong filenames. And that override with the %20 is windows - it will NOT work on other operating systems.
i exported to the Windows option, and all are working well.
As said above, that is because Microsoft implemented some really stupid overrides that looks for a wrong file if the originally used filename has some specific errors in it.
Just another example:
In every operating system but windows, ABC.jpg and abc.jpg are two different files, because A is a different letter than a (capitalization counts as different almost everywhere due to the way how letters are stored).
Now if you're telling the computer to load the file named ABC.jpg and he doesn't find it, then every regular operating system will return "file not found". Windows will instead search for and load abc.jpg even if that is a different filename even under windows - and it will not tell you that it loaded a different file than the one you asked for, instead hiding the capitalization error.
So if you have such a reference to a wrong filename it will appear to work under windows, and completely fail as soon as you move to any other operating system.
And depending on what exactly the file error is and what system is targeted, some files with wrong filenames cannot be copied at all - they are not deleted as you assumed, they simply couldn't be copied to start with because their filenames cannot be processed (for example if the filenames contain spaces, even Windows has to go through a lot of idiotic hoops to allow spaces in filenames because in MSDOS and early Windows versions they also were forbidden to be used in filenames for good reasons.
Okay i just be confused where i need to post
Anything that has to developing the content of the game goes into MV support. Everything after that (after you hit the "Deployment" button on the editor) goes into MV Deployment, exactly because it's then when the rules for other operating systems can get in your way, but not before.
