PeaZip 11.2.0 Report under Windows
Handling compressed files within PeaZip
It should be clarified that you can delete files using the Delete key (right-click on the compressed file) under File Manager -> Delete from archive in PeaZip's internal options.
Context Menu
When I right-click on an uncompressed file (a PDF, a DOC, or another file type), the PeaZip menu displays the options Extract, Extract..., Extract Here, Extract (smart), and Extract Here (new folder), which is nonsensical because you can't extract, extract..., extract here, extract (smart), or extract here (new folder) to a ZIP, RAR, or PEA file that isn't compressed in any of these formats.
In fact, WinRAR doesn't do this. For the same file, only the options Add to archive... Add to ["File name"].rar, Add to ["File name"].rar and send by email appear
Thank you for reporting, the Delete from archive entry does not show its keyboard shortcut (nor does the Move to trash entry), I'll fix it in the next version.
About extra options in system's context menu, this is a duplicate of what is described in issue 917.
In the original issue you can find the explanation for this behavior:
"PeaZip can handle many container formats which are basically archives with custom extensions, and also trying to parse arbitrary files as archives, this choice allows to conveniently handle them from the context menu (I understand it is not optimal if the user does not want to)"
