Hi,
It would be really useful if with a dataset loaded, you can open up another dataset and use this dataset as a filter against the original data table (based on a specified column such as Structure).
So besides the Append File.. option, maybe a Filter From File.. option.
Thanks,
Simon.

Hi Simon,
assuming both .dwar files contain a column of structures, DW's function «find similar compounds in file» possibly may perform the kind of sort you seek.
As a minimal example, I created a library of a few compounds around benzene and pyridine with some data computed by DW like molecular weight. This file (larger_group.dwar, attached below) was closed.
A second file was defined to contain only the structures of o-xylene, and 2-methyl pyridine (my_interests.dwar). From this file, I accessed chemistry -> Find Similar Compounds In File to encounter a new menu shown below. The file to scrutinize was indicated in the first field (larger_group.dwar), and the structure criterion was set to be exact. It is possible to use a less strict, and adjustable structure comparison, which is the one suggested by default, though.
Then, I opted to retain all of the data already computed in larger_group.dwar to be transmitted to either the new file about matching structures (keep_these.dwar), or to export the entries not needed now (file removed_these.dwar).
The scope of structures of the two files newly written is complementary to each other, and adds up to the set of structures in the initial file, larger_group.dwar.
