[REQ]DOCX deflation

[sirfragalot]

Is your feature request related to a problem? Please describe

I'm doing a PHP HTML —> DOCX convertor and it would be useful to be able to compress the DOCX folder to a .docx file that opens in Word, LO, etc. for testing purposes. (Uncompressing a .docx file to a DOCX folder with Keka works perfectly fine.)

Describe the solution you'd like

DOCX uses the DEFLATE compression algorithm. I know little about compression, but I have tried every single compression option within Keka without success. Unless I have missed something, it would therefore be great to have a DEFLATE compression in Keka suitable for creating .docx files.

Describe alternatives you've considered

I could use PHP's \ZipArchive::CM_DEFLATE to accomplish this, but it would be a lot easier to just drag the folder to Keka.

Additional context

Other than that, a beautiful piece of work is Keka. Thank you.

Hi @sirfragalot,

You can recreate the docx using Keka and the zip format. Just be sure to compress the structure (_rels, word...) and not the containing folder.

You can also use the "Compress the contents of the folder" option in the Finder Extension with the parent folder:

Just be sure to rename the zip extension to docx once compressed.

What a quick response aonez—thank you. I must be doing something wrong because both LO and Word report a corrupted file when I try to open. If I unzip the compressed file, the structure is as I expect—so that part at least seems fine.

Now I've tried actually opening with Word (I don't usually use it) and I'm seeing the issue you mention.

[sirfragalot]

Same thing with LO (LibreOffice).

I've used TextEdit and Pages without issue, that's why I did thought about file structure.

Seems like Word (and LO probably) expect the older deflate method and does not accept deflate64.

You're having more luck than me. TextEdit and Pages won't open the file for me.
