[xwiki-users] Can I upload files larger than 32MB

Hello I do not have a Wiki at the moment and was looking at a few options. XWiki looks like a good choice but I am not familiar with Wiki (this on too) and have a few questions please. Can someone please assist with the following quires. 1: Is XWiki free? 2: I have WEB space on a Unix/Linux hoster e.g. PHP, MySQL etc.. Will this Wiki work on my WEB space e.g. what language is it written in? 3: Do I need root access to my WEB space in order to install/configure/maintain this Wiki 4: I have a quick look at the sandbox and tried to upload a video which was more than 32MB, I received the error that the file was too large. With my WEB hosting the storage is unlimited therefore can I configure XWiki to upload say files up to 200MB for example? 5: If I upload say MP4 and Windows Media Files to my XWiki site, will the play inline without the user having to have either an MP4 or Windows Media player installed? 6: Will the search engine that comes with XWili search "inside of files" as well as the file names? i.e. is there an option to say also search file contents. Thanks all for your time EBrant
