Extract files from an archive residing in an archive

[ags1905]

Scenario
FC does not know how to correctly extract files from an archive inside another archive.

Steps to reproduce
- download file: https://sourceforge.net/projects/aim-to ... p/download
- enter the archive with <Enter>
- go to files.cab and enter with Ctrl+PgDown
- select all files with * and press F5 to extract to the other side

Actual behavior
The files get deselected but they are not decompressed to the other side.

Proposed behavior
Files get extracted as expected.

I can confirm a problem with the fc7Zip plugin.
Fixed for the next release.

Workaround:
- add cab extension to "File Extensions" of the plugin and use Enter to open the cab file
- select not all items to copy
