How to import a XAR larger than 100MB?

If you get an error, such as:

Cannot import large xar. Error "java.util.zip.ZipException: error in opening zip file"

Then you should use one of the following solutions:

• Turn on filesystem attachment storage
• Use the Large XAR import extension
• Use the Filter Stream Converter Application to read in the file as a "xwiki+xar" and convert it into the format "xwiki+instance" (which stored the data in the wiki)
