None of the files with numeric extensions (001, etc) are useful.

There are 3 GL data files with CMH extensions dated in 2003. There are no longer useful either.

The .HLP and .CHM help files should be installed elsewhere and not on the root. These are not required here either, and in general are quite old anyway.

As Doug mentioned, the QR files (with QRW extensions) should belong in the QRASP directory. I presume that since these are generally quite old, I bet they are not useful either. Those with TXT extensions are definitely useless and they can be gassed.
