Hey, I know how much is the maximum size of the file for free hosting? I tried to upload large files, but not what I have achieved.

I would also like to know whether it is possible to increase it but free. Thanks in advance for their assistance. Greetings.

File limit is around 20mb via FTP and I think it's 2mb via control panel.

And no there is no free way to up this limit. As this is "Webmaster Hosting" you should have no need to upload anything larger than 20mb. IMO 20mb is even kind of high considering there are many file sharing sites out there with limits of 100mb and up!
