How do I use special characters in paths?

[iprowell]

I am writting an application that writes images to a WebDAV drive.  To communicate parameters to the application controlling the WebDAV drive I add extensions when creating a directory.  If I execute "mkdir R:\fwVideo"@a=100000&c=1000" on the command prompt it will make a folder called R:\fwVideo that has a 100000 frame archive and 1000 frame cache.  I would like to be able to create this directory from my LabVIEW code, but when I give the path "R:\fwVideo"@a=100000&c=1000" I get a LabVIEW error.

"LabVIEW: An input parameter is invalid.  For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @. ..."

How can I disable this error checking? 

Thank You,

I'm afraid I'm not familiar with with the functionality of a WebDAV drive, but methinks if all else fails, rather than using any of the built in File I/O VIs, couldn't you just specify the "mkdir" command through SysExec?
