Rename inside archive

[Dec]

Why WCX plugin interface does not provide rename functionality?

[MVV]

Perhaps because most archivers don't allow that.

I would say this is because none of this Tools/Plugins works inside an archive. If you change something inside an in really it unpacks temporary and repacks it again. An renaming operation would happen inside therefore it isnt possible.

If structure of archive allows user to rename a file inside archive (for example file list is stored at the end of the file of archive and rename operation does not require to rewrite whole archive) imho it will be good idea to add rename functionality to WCX interface. If plugin implements rename function - user can use it. If don`t - user will use "classic" way with with creation of the new archive and coping content of old to new.

If you change something inside an in really it unpacks temporary and repacks it again.

Realization of rename functionality is plugin specific. If plugin author want to implement it - his rename function will do all unpack/pack operations much more efficient and fast than Total Commander and user.

ghisler, could you explain your point of view? You implemented rename functionality inside ZIP archives. Why don`t you want to add the same for other WCX plugins?

sure?

well - i´m no coder, but if it would be as simple as setting a switch or so i believe most of the coder whould be do it.
but if this means to rewrite a tool/plugin/whatever - i´m not sure....

I am developer so I am sure.

No one can force the programmers to update their plugins. But add rename functionality is not the same as rewrite whole plugin.

Still waiting for ghisler comment.

i understood already that you await and expect an answer from christian

well - you know the default answer "if you miss something - code it yourself"

"if you miss something - code it yourself"

It is not a problem for me to develop additional functionality in my plugins. But without integration with TC any new additional code is useless. Who will call my rename function?

Renaming is problematic when the length of the name changes - normally the entire archive has to be copied to adjust to the new name length. Some archives may even need complete re-packing, e.g. solid 7zip. There is currently no plugin function for renaming. All plugins would have to be updated to support it, which is very unlikely.

Problematic does not mean impossible. And there are a lot of "archive" files in which rename function is easy to implement. Different disc WCX and etc.

There is currently no plugin function for renaming. All plugins would have to be updated to support it, which is very unlikely.

Why don`t you want to add rename interface for developers who can and want implement it. When plugin does not implement DeleteFile - TC just shows "Not available" (or something like this, I don`t remember). And when plugin does not implement RanameFile - just show the same message.

If you add rename interface there is a chance that developer will update plugin and end user will have rename functionality. But if you don`t add - there are no chances at all.

solid 7zip

In solid archives only file contents is streamed, not file attributes - they are in a table so only this table should be recompressed (and of course all data needs to be shifted).

I think this is something that the plugin author can decide.

I currently don't see why it cannot be optional.

Is there any chance this request will be added in the next version of Total Commander?

[ghisler(Author)]

I'm indeed considering it for TC9, although there are still some unresolved problems like handling of the GetPackerCaps function - TC currently stores the flags in the wincmd.ini and does NOT update them when installing a newer version of the plugin.
