In the "import multiple ascii" dialog box, how do you control the order of files added? That is, in Version 6.1 and earlier, if I select data_file000.dat and data_file001.dat (which are listed in that order in the upper file list) and click "Add files", they appear in that order in the lower file list and are imported into the worksheet in that order. In Version 7.0, those two files are reversed in order in the lower list. If several files are selected before clicking "add files" the order in which they are added to the lower list seems almost random. I can select them one by one and add them, but that's much slower.
You can order the lower list itself by clicking on a column header... File Name, Size, Modified. Those choices don't cover all possibilities, but it's the standard Windows method.
