Description Xiaonan Jiang

2010-06-09 11:13:05 EDT

Build Identifier: 3.6RC3

From the javacore, looks like the time is spent on traversing the file system. this is unnecessary since the folder and filename can be retrieved from the import wizard.

It is not actually a hang, but it does take a long time. I agree it shouldn't need to recursively populate the entire file system model at this point.

This seems to be a dup of bug 312959
