In the Delphi 7 programming environment, how does one open an xc_pk_xcprn.bpl package?

In the open window, select
Directory: D: \ computing programming materials \ Delphi \ item name input Window project
File Type: any file (*.*)
File Name: xc_pk_xcprn.bpl

Error message window: unable to find package source D: \ computation programming materials \ Delphi \ product name input Window project \
Xc_pk_xcprn.bpl or compiled package D: \ computing programming materials \ Delphi \ product name input Window project \ xc_pk_xcprn.bpl.

Strange, this file exists under the project \ in the D: \ electrocomputation programming materials \ Delphi \ product name input window, xc_pk_xcprn.bpl!

. BPL is similar to DCU. If you cannot open the DCU file, you must find the PAS file. If you want to open the BPL package, you must find the dpk.

It seems like this.
