Q:
How to scan for duplicates with Gemini 2?
A:

Take the following steps to start searching for identical and similar files on your Mac: 

  1. Open Gemini 2.
  2. Click the Plus (+) button in the center of the screen and then choose one of the offered locations or add a custom folder. Alternatively, drag the folder or drive to the screen. 
  3. Click Scan for Duplicates.
Q:
Is Gemini 2 safe to use?
A:

Gemini 2 uses smart scanning and analytic algorithms that filter out both duplicates and files that have minimum changes. However, by default, the app automatically offers for removal only 100% identical items and always keeps safe at least one of the kind. Moreover, you can restore all removed items from the Trash folder unless you've manually changed removal preferences. Also, note that Gemini ignores system data so you can be sure that nothing relevant to your macOS can be accidentally deleted.

Q:
What are limitations of the trial version?
A:

The trial version of Gemini 2 can scan through your Mac any number of times and analyze any amount of data. However, the app can clean up to 500 MB data only. To remove restrictions, you need to purchase a license and unlock your version of Gemini.

Q:
How does the Smart Selection feature work? Is it safe?
A:

Gemini thoroughly compares files by analyzing file creation and modification dates, extensions, paths, and other parameters. Then, it defines identical items and those that are almost alike. Only absolute duplicates are selected for removal automatically. Smart Selection doesn't offer removing similar files by default. Moreover, system data and unique information aren't ever selected or offered for removal, thus the feature is safe and doesn't affect any valuable information.
As you use Gemini, its Smart Selection algorithm also learns the way you make choices and offers you to add some new Smart Selection rules.

Q:
How do I remove selected duplicates?
A:

After Gemini has scanned some location, you see a scan summary. You may choose to check what Gemini 2 has found by clicking the Review Results button, or you can click the Smart Cleanup button to automatically remove selected duplicates.
To remove duplicates from the detailed results screen, click the Remove/Smart Cleanup button in the lower-right corner. 

Q:
Can I restore deleted duplicates?
A:

By default, Gemini 2 moves all items to the Trash instead of permanently deleting them. So, if you find that something important has been removed, you can either restore it from the cleanup complete screen or put the file back from the Trash later. Please note that you can't bring back files if you have changed the default Gemini's Removal preferences to permanent removal.

Q:
Will Gemini 2 remember my scan results?
A:

If you want to save Gemini's scan results and return to reviewing them later, quit Gemini using the Command - Q shortcut. In this case, the results are automatically saved and immediately restored when you re-open the application. 

Q:
Can I scan multiple folders at a time?
A:

Yes, you can select any number of folder and drop them to Gemini 2. However, please note that although Gemini’s scanning is usually fast, the more folders you add, the more time is needed to complete the scanning.

Q:
Can I scan removable media?
A:

Yes, you can either drag-and-drop these media to Gemini 2 or click the Plus (+) button and then select them in a Finder window. Please make sure you have the read and write access to the volume you’re going to scan. Also, note that you may not be able to restore items deleted from external locations unless they have a Trash folder.

Q:
Can I scan network volumes?
A:

Yes, you can either drag-and-drop a volume to Gemini 2 or click the Plus button to select it in a new Finder window. Please make sure you have the read and write access to the volume. Also, please remember that if the volume doesn't have a Trash folder, the items are removed permanently.

Q:
What are the Achievements in Gemini 2?
A:

The more actively you use Gemini 2, the more achievements and ranks you unlock. For example, you get new achievements for scanning your iTunes library or sharing your cleanup results on Twitter. When all achievements are unlocked, you get a reward. Have fun!

Q:
Can I scan my Photos and iTunes libraries with Gemini 2?
A:

Yes, the new version of Gemini is fully compatible with the Photos and iTunes apps. However, it needs your permission to scan through your libraries, so please give your approval to Gemini when it prompts you to open Photos and iTunes.
Note that due to Photos' restrictions, Gemini 2 cannot move files from your library directly to the Trash and thus puts them to the Gemini Duplicates folder. To remove these items completely, please move them to the Trash manually.

Q:
Can Gemini 2 replace files with hard links?
A:

Yes, Gemini 2 can replace duplicates with hard links if you change Gemini 2 removal preferences. To do this, go to Gemini 2 → Preferences → Removal tab and select the "Replace files with hard links" checkbox. From this moment, Gemini will replace duplicates with hard links instead of moving them to the Trash.

Q:
What are Gemini 2 requirements and compatibility?
A:

Gemini 2 requires macOS 10.10 or higher and around 65 MB of free space. If upgrades to OS X Yosemite are not available to your Mac, check out Gemini Classic. It was designed for earlier macOS versions and supports systems starting from macOS 10.7.

Q:
What's the use of the pie chart on Gemini’s scan results screen?
A:

The pie chart shows which categories of duplicates take up the most of the disk space on your Mac. Just hover over a colored section of the chart to see a category name and its size. To take a closer look, click on the section, and Gemini will open the detailed results screen with all duplicates of this kind filtered out.

Q:
The file I’ve deleted still appears in my scan results, why?
A:

If the file is being used by a system process, or your user account doesn’t have the proper permissions to delete it, the file won’t be removed by Gemini 2. This is why it might appear in your scan results again. 

Q:
Why eggs, why Gemini?
A:

Gemini is a constellation in the Northern Hemisphere, also known as the "twins." Duplicate files are identical, like twins or two eggs, which is why we used these themes in the name and the logo.

Q:
Why do duplicates from the Photos app get placed to the Gemini Duplicates folder?
A:

This happens because third-party applications are not permitted to remove any files from Photos. So, instead of moving duplicates from Photos to the Trash, Gemini 2 puts them to the separate folder, “Gemini Duplicates.”

Q:
I've cleaned all duplicates in the folder but Gemini 2 shows new duplicates after a rescan, why?
A:

Gemini 2 intentionally limits the number of duplicates that are shown in the duplicates list. This way, it prevents you from getting lost in dozens of small duplicates and reduces the scanning time. Thus, if a number of found duplicates exceeds the acceptable limit, Gemini 2 shows only the largest duplicates.

Q:
I've cleaned duplicates but Finder shows the same amount of free space on my drive, why?
A:

When you clean your Mac with Gemini, the app moves all deleted items to the Trash folder so that you could restore them if needed. However, in this case, removed duplicates continue to occupy space on your drive until you empty the Trash. If you are sure there's nothing useful, just empty your Trash to increase free space on your drive.
