7z limitation or bug?
-
Hello,
I can not simply drop a file over an existing 7z archive in order to add the file as i can do it with other archive formats (eg: zip).
Is a fix for this planned or is this a limitation with this (new) 7z archive format?
Thanks.

7ZIP is a solid archive format just like CAB.
It’s an limitation of 7ZIP unfortunally.

This is a limitation of PowerArchiver…
7-ZIP supports both solid and non-solid archives.
but PA can’t determine whether archive is solid or not.
I hope the future PA releases will support updating 7-ZIPs

It is both - on one side, PA can not detect non-solid archives, on the other side, most 7zips are solid anyway since there is an huge benefit to compression strenght.

what are the advantage if creating a solid file compared to a non-solid one?
-
Solid archiving significantly increases compression, especially when adding a large number of small, similar files.
But it also has a few important disadvantages:
-
slower updating of existing solid archives (you have to repack all the files);
-
to extract a single file from a solid archive all preceding files must be analyzed. This makes extraction from the middle of a solid archive slower than extraction from a normal archive, but, if all files are to be extracted from a solid archive, the extraction speed will not be affected.
-
if any file in a solid archive is damaged, it will be impossible to extract all files which follow the damaged area.
