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
Converter - delete original

I didn’t see this request here, but I guess it will be easy to code and very helpful for those who have thousands of zip archives and wish to convert them to 7z.

… thousands of zip archives and wish to convert them to 7z.
Thousands ??
Deleting thousands of files automatically really scares me!
But then again thousands of prompts would scare me even more :mad:Once only - {Are you sure?
Are you really sure?
You don’t want to change your mind?}Error - out of memory / disk space :eek:

If those files are in same folder, use converter to convert them and make sure new files are placed in some other folder. Then manually delete those files - if there are other files around, you can use search for specific format and then delete them.
Reason we dont want to have delete option in converter is that there are too many possibilities of something going wrong.
thanks,

The possibility that something can go wrong is up to the user, or are you mentioning program bugs?
Winrar does a fantastic job of converting files. I guess is the current reference in that matter. Unfortunately it doesn’t convert to 7-zip.
I have 8gb of zip archives with office documents spread through many directories. Converting them would recover about 3gb of disk space.
Now, you see my problem :D -

Now, you see my problem :Dbasically i dont think there is an way to properly verify that 8 GB of zip archives were sucessfully converted into 7zip. Hence, no delete option.
But you can still do what I originally suggested (use Windows search for all .zip files and then delete them).
thanks,

Winrar does it. It converts, tests and deletes every archive. But that’s ok. I’ll have to search all zip, convert about 400mb at a time, than delete them, because I only have 500mb free in this partition.

P.S. Maybe save them on CD / DVD to free hard disk space?
You should also consider converting to CAB format. This usually gives better compression than 7z with MS Office document files - also have a look at PACL (command line/batch file tool) to do this.
