Dear all, I am using Parallels desktop for running ArcGIs Desktop in Windows Xp Pro operative system. My problem is that ArcGis has a sort of script file where it stores the complete path of the files in use and some of them are archived in external hard disks. Unfortunately most of the time I connect the external HD to the mac it comes in Windows with a different letter which makes the use of the previous scripts awkward. Does anybody knows any work-around to that problem?
