Quartus Prime software Archive feature uses the wrong .qpf file to update the SEARCH_PATH assignments in the .qsf file

The Quartus Prime software Archive feature fails to update the Quartus Settings File (.qsf) SEARCH_PATH assignments with the correct restored paths if the current directory contains a Quartus Prime Projects File (.qpf) with a file name that alphabetically precedes the .qpf file within the Quartus Prime Archive File (.qar).

Consider the following scenario:

1. You have an abc.qpf file.
2. You have an xyz.qar file that you want to restore, and xyz.qar contains an xyz.qpf file.
3. You run the quartus_sh --restore xyz.qar command to restore the xyz project archive to the current directory.

Because abc.qpf alphabetically precedes xyz.qpf, the Quartus Prime software opens abc.qpf and attempts to update abc.qsf with the modified restored paths, instead of opening xyz.qpf and updating xyz.qsf.

This problem affects both the Quartus Prime Standard Edition software and the Quartus Prime Pro Edition software. In the Quartus Prime Pro Edition software, this problem causes an internal error.

Before restoring the .qar file, remove from the current directory any .qpf file that alphabetically precedes the file name of the .qar file.
