[Pharo-users] Trouble opening large files

Hello, I've run into some odd behavior and wanted to check whether I might be missing something: I have downloaded a copy of the english wikipedia as an xml file and am hoping to (sax) parse it. However, I can't even seem to get pharo to recognize that the file exists. If I open FileSystem disk root in the playground and naigate, attempting to enter the folder containing the (57G) xml file fails with "MessageNotUnderstood: False>>humanReadableSIByteSize." Likewise if I get a FileReference with FileSystem disk root / 'path' / 'to' / 'file' then self exists returns false and the parser fails. Am I doing something wrong? Should I be able to do this? The version number is #40283 Thanks, Evan
