Just started using UC for Linux and cannot seem to get the hang of it. I was an extensive Windows UC user but there seems to be a difference. Simply put, I just wish to compare files on two different storage devices – my working stuff and and my backup media. I have reviewed the power tips and I really just need to get to the first level – just get it working. I am trying to do a folder to folder compare. 

Also following the YouTube videos do not apply to my Unix UC. 

Appreciate any "booting" guidelines. 

Thank you.

I use UltraCompare just on Windows.

But to be able to post a reply, I installed UltraCompare for Linux 21.00.0.18 (the Ubuntu 18.04 DEB package) with sudo dpkg -i ucx_21.00.0.18_amd64.deb in a virtual Linux machine with Debian 10 (Buster).

This Debian 10 virtual machine has /etc/apt/sources.list with the lines:
There were missing dependencies for libjpeg8 and poppler-utils.
 
I needed to do following for that reason before I could install ucx_21.00.0.18_amd64.deb:

1. Install multiarch-support 2.28-10 with sudo apt-get install multiarch-support (required by libjpeg8)
2. Download libjpeg8_8d1-2_amd64.deb and install libjpeg8_8d1-2 with sudo dpkg -i libjpeg8_8d1-2_amd64.deb
3. Install poppler-utils 0.71.0-5 with sudo apt-get install poppler-utils

Then I could start UltraCompare on the virtual Linux machine and I could see first:

Initial window of ucx 21.00.0.18

It should be easy to start a folder comparison with that window as there must be just clicked the Folder button to get:

Folder compare window in ucx 21.00.0.18

There must be just selected a folder for the left side and another one for the right side with drag and drop or with using the two open folder buttons. UltraCompare for Linux executed the folder comparison automatically after selecting the right folder. There could be clicked on the green arrow button (play button) in the middle if the comparison is not automatically done.

Clicking in menu Session on the menu item Session Properties… opens the Session Properties window for the active comparison tab where it is possible to change the properties (options) for the folder comparison (or whatever comparison is done in active tab) and run the comparison again on clicking on button OK and Run at bottom left of the dialog window.

There is docked by default on right side the Legend & Filters view which is shown on clicking with the mouse pointer on its tab. This view explains the items used to mark equal or different files and folders.

It is of course possible that a different comparison like a text file comparison was done before. But clicking in menu Mode on the menu item Folder Compare or pressing Ctrl+K changes the compare mode from text file to folder compare.

Switch compare mode from text to folder compare in ucx 21.00.0.18

Thank you for all the effort; I sincerely appreciate it!

I am running native Linux Mint 2x.xx something and the stock installs done with purchased packages worked peachy keen dandy. It was a case of "gross ignorance" that prompted my cry of desperation. 

I too have been a long time user of UltraCompare in the Windows environment. Thank you for the extraordinary effort and your answer. I appreciate it. In the interim, I had discerned this through plunging ahead and banging into obstacles. But I have nearly mastered it. Of course, like UEX, there are some differences and idiosyncrasies. Somewhat like UC for Windows, it takes a while of experimenting.   

Before closing out, I would comment that I took the time (and will continue to reread) your forum rules comment and understand your efforts there. I applaud your putting together -- through this forum -- an increasingly comprehensive collection of FAQs and Power Tips (and possibly tutorials).

I recently left the Windows world because of the absolutely horrid W11 and turned to Linux which, to date, has been a thing of joy and discovery. The one thing that was missing was UltraEdit (and UltraCompare). I was/am a software developer since the late 60s and coincident with my experience with Windows 3.1 was my introduction to 16-bit UE.* It and subsequent versions have been the main tool in my chest since then. A sad to however, UE and UC under Wine is a clumsy affair. Consequently, the upgrade to UEX and UCX.

But there seems to be a difference in what my UE for Windows (and UC for Windows) and what the Linux versions offer. So it seems that I have a learning curve ahead of me and, in reading your post It occurs to me that my questions or discoveries worded to adhere to your guideline would benefit your effort. 

At the moment, I am heading back to really read the FAQs and Power Tips to extrapolate all I can before I post another silly question as the one above. 

Kindest regards!
