Q:
What if my Gemini 2 activation number doesn’t work?
A:

First, check to make sure that you entered your activation number correctly — maybe you’ve accidentally copy & pasted it with spaces or other invisible symbols.

If you lost your Activation Number or the app gives you a message that it is already used, you can take advantage of our License Retrieval feature to retrieve the number and reset earlier activations, if needed.

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

To start scanning for duplicates, launch Gemini 2 and click on the “+” button in the center of the screen, or drag-and-drop the folder or drive you wish to scan into that screen. After that, click Scan for Duplicates.

 

Q:
Is Gemini 2 safe to use?
A:

Gemini 2 is 100% safe to use. Its scanning algorithms keep vital system files intact. You can rest assured that you won't remove files that can affect your system performance. Also, if you delete duplicates with Gemini 2, you will still be able to restore them, because Gemini 2 does not erase these files, it only moves them to the Trash.

 

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

The trial version of Gemini 2 will scan all your files, but is only capable of removing 500MB of duplicate files. When you unlock the full version of Gemini 2, you will be able to remove an unlimited amount of duplicates.  To unlock the full version of Gemini 2, please purchase it on the App Store or on the MacPaw Website.

 

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

The Smart Selection algorithm analyzes file parameters, such as size, name, modification date, and more. Based on the above, Gemini 2 defines what instances of files look like duplicates. Smart Selection only targets duplicates and always leaves one instance of every file untouched, so it is completely safe to use.

 

Q:
How do I remove selected duplicates?
A:

After you have scanned a folder, you will see a scan completed screen. You may then choose to review what Gemini 2 has found by clicking the Review Results button, or you can click the Smart Cleanup button to automatically remove selected duplicate files. 

To remove selected duplicates from the Review Results Screen, click the Remove button in the bottom right-hand corner. This will remove the check-marked duplicates on the list.

Q:
Can the deleted duplicates be restored?
A:

By default, Gemini 2 does not permanently delete files. Instead, they are moved to the Trash, so if you find that something important has been removed, you can restore it from the Cleanup Complete screen, or put the file back from the Trash.

Note: files cannot be restored if you have changed the default settings and selected Remove permanently in Removal preferences.

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

If Gemini 2 is closed before you process the scan results, they are automatically saved and will be immediately available when you re-open the application.

 

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

Yes, you can select them all at once by using Command-Click, and then drag-and-drop them to  Gemini 2. Note that although Gemini’s scanning is fast and efficient, the more folders you select to scan, the more time it will take to scan them.

Q:
Can I scan removable media?
A:

Yes. You can either drag-and-drop them to Gemini 2, or select them in a new Finder window that will appear after you click the “+” button. However, you need to make sure that you have read and write access to the volume you’re scanning.

Q:
Can I scan network volumes?
A:

Yes. You can either drag-and-drop them to Gemini 2, or select them in a new Finder window that will appear after you click the “+” button. However, you need to make sure that you have read and write access to the volume you’re scanning. Also, please bear in mind that these volumes have no Trash, so the items will be removed permanently, unless you select Move to folder in Gemini’s Removal preferences.

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:
Does Gemini 2 work with my Photos and iTunes apps?
A:

Yes. If you have files in your Photos/iTunes, Gemini 2 will scan them for duplicates. Be aware that in order to find duplicate files in your iTunes and Photos libraries, Gemini 2 will need to launch iTunes and Photos. Please allow Gemini to open them and select Always Open, when prompted. 

Although Gemini 2 can scan files and folders from Photos, it cannot move these files to the Trash, so it organizes them into a folder called “Gemini Duplicates” instead. You can manually move these files to the Trash after the scan has been completed. For more details, please refer to our Knowledge Base Article here.

Q:
Can Gemini 2 replace removed files with hardlinks?
A:

Gemini 2 can replace files with hardlinks if you set this as a preference in Gemini 2 preferences. Go to Gemini 2 > Preferences > Removal and mark the Replace files with hardlinks checkbox. This will make Gemini 2 replace duplicate files with hardlinks instead of moving them to the Trash. To read more about this feature, please refer to our Gemini 2 Knowledge Base Article.

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

Gemini 2 requires OS X 10.10 or newer and around 65 MB of free space. If upgrades to OS X Yosemite or El Capitan are not available for your Mac, check out Gemini Classic instead. It will help you clean up duplicate files, as it has been designed for earlier Macs and works on systems starting from OS X 10.7.

Q:
What is the pie chart on the left of Gemini’s scan results window for?
A:

The pie chart shows which categories of duplicates take up space on your Mac. You can click on parts of the pie chart to filter the duplicates and (if needed) quickly locate and delete the most space-consuming files.

 

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. Still Gemini 2 will warn you about that on the Cleanup Complete window.

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 the duplicate files from Photos app get placed in a folder titled “Gemini Duplicates” inside that app?
A:

This happens because other applications are not permitted to remove any files from Photos. So, instead of moving the duplicate files from Photos to the Trash, Gemini 2 will organize these duplicate files in a folder in the app itself and title it “Gemini Duplicates.” You can then review the files and decide what to do with them. To get more details on that, please check our Knowledge Base Article here.

Q:
I have cleaned all duplicates in the folder, but after a rescan, Gemini 2 shows new duplicates. Why?
A:

Gemini 2 has a limitation on the number of duplicates that are shown on the duplicate list. It is designed this way to prevent you from getting lost in dozens of small duplicates that require time to be examined. If the number of found duplicates exceeds the acceptable limit, Gemini 2 will show only the largest duplicates that were found.

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

When you clean duplicates with Gemini, the app moves them to the Trash. This allows you to restore the files in case you accidentally delete something. So, until you empty the Trash, these files will still occupy space on your drive. If you are certain that you don’t need the deleted files, just empty your Trash and the free space on your drive will be increased.
