90 | * A variant of the standard resource import wizard with the following changes: |
91 | * <ul> | |
92 | * <li>A folder/file combined checkbox tree viewer to select traces | |
a94410d9 MK |
93 | * <li>Cherry-picking of traces in the file structure without re-creating the |
94 | * file hierarchy | |
12c155f5 FC |
95 | * <li>A trace types dropbox for optional characterization |
96 | * </ul> | |
a94410d9 MK |
97 | * For our purpose, a trace can either be a single file or a whole directory |
98 | * sub-tree, whichever is reached first from the root directory. | |
