Improvement and feature requests by users are taken in consideration and you can often find your bug report resolved or improvement request fulfilled in one of the beta versions that follow soon.
Con Takes a while to get used to
After installing F.lux, the screen will look a lot more yellow. This takes about a week to fully get used to. You can ease into it by setting the color temps higher than the recommended defaults.
Compared to the other options, Directory Opus is quite expensive.
Prices are $35 for the Lite version and $64 for Pro (price changes based on the AUD to US exchange rate). Upgrading from light to pro costs about $30.
Con Portability costs more
On top of an already expensive license, users must purchase a separate Export License to create a portable version.
Con Only available for Windows
Con Restrictive license
Product is licensed on a "per-machine basis" requiring purchasing multiple expensive licenses to cover a single user with multiple machines.
However, if you have time and luck, you can write to the DO sales department and they can produce another license for you to use personally on another machine you own.
Con Complicated if one pursues mastery on the most advanced features
Takes a long time to become efficient with it. Mastering all the features can be rather exhausting.
Con Can be intimidating to novice/inexperienced users
While the program is ULTRA-customizable, this can be a double-edged sword to anyone that is overwhelmed easily or not willing/able to learn the inner workings of DOpus.
Con Large file sizes
The installer weighs in at 50MB and the app directory is over 95MB.
Con Limited to only two views
You are only able to have two concurrent views at a time.
It does help, that you are able to have both the metadata-pane and the viewer-pane open whilst using Dopus in dual-view mode.
Con Limited support for Touch / Tablet mode
Your file manager + Start Menu are the main way to launch programs/documents... When using Touch Mode, the Surface running Opus would be far more usable if some attention was paid to this use case.
Con No good support for right-sided tree
The only way to get a right sided tree is to display both panes in horizontal layout and then switch the first (upper) tree off. Which leaves you with 2 horizontal panes and one tree on the right. There is no other way (neither with 2 vertical nor with 1 pane) to have a tree on the right side. And since this layout setting is rather the step-child of the developers, it also is a bit buggy and not of top priority as far as fixing any issues with it.
Con Erroneous Con
Con has been deleted, as it stated untruthful information.
Con No native/good support for restoring multiple search paths for the find files tool
Although all other options of the find files tool are very good, there simply is no easy way of regularly using the same multiple search paths.
For using only one search path, one can simply navigate to that path and activate the automatic path-use-button in the tool or choose one path from the previous paths drop-down, but that only works for one path. It can get cumbersome if one wants to restore multiple search paths at once. One must basically write his own script to do that. This is surprisingly annoying that such a basic and needed functionality is not natively supported (built-in) by such a generally powerful program.
