#622 Peazip doesn't show in right-click menu if number of files selected > 100

I had used peazip from the right-click menu to create archives larger than 600 mb. My OS is Windows 10, 64bit. I had a folder with 102 files that when I used right-click, Peazip was not showing up in the right-click menu. The total size was only 403 mb, so I knew size wasn't the issue as I've created larger (in mb) archives than that before. The issue seems to be the number of files.

When I highlighted 1 - 100 files and right-clicked, peazip showed up in the context menu. As soon as I went above a 100 files though, peazip no longer shows in the context menu.

The 100 items limit is built in in Windows for some types of context menu entries.
You can get past this limit selecting the entire folder (which the system will count as a single item), or dropping the files on PeaZip icon or on a PeaZip window (which is faster), or selecting the files from PeaZip file manager itself (which is the fastest way, as no feedback from the system is needed).

That can't be it, or at least if it is, there are ways to get around it. The reason I say that is because with the exact same folder with over a 100 items, I tried both Winrar and 7zip to see if they did the same thing (I don't have Winzip to try that one). For both of those, right-clicking on >100 files brings up their menu choices for adding to archive and other options. It's only peazip that doesn't.

Yes, there are various way to create system context menu items.

The way used by PeaZip avoids registering a dll to handle integration with context menu, rather using a dynamic verb (it is a new method supported from Windows 7 onward), but suffers this limitation which is common to non COM methods.
I hope to be able to improve this aspect in future.

Ok, that's interesting.

I hope you can too. Thanks.
