Description Soukyuu 2015-06-02 11:18:07 UTC

There does not seem to be a way to set any compression options - it always uses the default. With formats like 7z and rar, this is way too inflexible.

There should be an "options" button on the "add file" dialog, which either leads to a configuration dialog for this format OR at least a text field for a "custom command line", where the user can enter any custom switches the format supports. The layout of the option dialog could be copied from tools like 7zFM or winRAR.

Reproducible: Always

Steps to Reproduce:
1. create a new archive
2. add files
3. save archive

Actual Results:  
Archive is created with default settings for that format

Expected Results:  
Ark should provide a means to configure various compression settings for the chosen format

Sorry for the delay and thanks for reporting. There is already a similar report, so I'm marking this as duplicate.

While this one was marked a duplicate of #148702, mine goes further: being able to specify archive compression is of course great, most formats allow to play around with other options to squeeze out even more bytes. Notable examples include being able to increase the dictionary size in 7z and winRAR5

I'm not sure if the current implementation is only the first step, but please consider adding ALL format options to the configuration window - a text field to enter them manually is fine by me, too.

You don't mean this one that is included in Ark?

7z compression options

Yes, but as I said in #c2, there are some things missing, for example dictionary/word size etc (see a screenshot of 7z options attached). That's why I proposed an "additional command parameters" edit field to pass the commands directly to 7z in case those missing options are too many to fit into the UI.
