Can you include .3MF to the list of re-compressible formats? Its structure is similar to MS Office 2007 documents and Open Document Format. It is a ZIP Deflate archive with XML data and some JPG, and/or PNG pictures inside. Otherwise, if I try to compress .3MF it bearly makes it smaller unless I recompress .3MF to the Store setting then it makes it a lot smaller.
Wish they all would move to 7zip ZSTD in the first place so that the optimized file size with FileOptimizer would be 50% of the ZIP Deflate version. And there would be no extra compression needed :)
I noticed that the option to add the optimize archive function to the context menu is missing on Windows 10.
Opening each archive with the interface in order to click it becomes tedious with many files.
Same for others functions like Remove Archive Encryption
Split 7zip file task and split file profiles
-
I’d like to have functionality for splitting files.
I’d like to be able to split a 7zip file to convert it to multi-volume.
I need profiles for split and ability to add split task to queue. -
You can create split archives - PA calls this “Disk Spanning” for historical reasons.
However, to “split” an existing archive is only available for Zip - other types have to be done manually (extract / re-compress).
-
Splitting 7zip file is like splitting any other file with a common split /combine tool found in file managers (split / combine in speed commander or total commander)
What i am suggesting is that PA support also generic split/combine jobs with profiles suitable for various archive types.
-
But that generic type of splitting does not create “multi volume” archives which you said you wanted, these “splits” would have to be re-joined before you could extract from them.
“Spanning” is part of the compression function and these do not have to be re-joined before extracting (hence the term “multi-volume”.
I was agreeing that spanning would be useful for other formats such as 7zip - but for generic splitting I think there are already good utilities available. (eg HJSplit ).
-
I use GSplit for splitting 7zip archives.
As long as 7zip naming standard is respected 7zip sees the split files as multi-volume and is able to extract them.
