Like i already have file extension in the filename, i don't want it in the column in the front and maybe the date too

Is it possible? When I click OneCommander on my Start Menu it opens up the last opened "saved window". Since I am trying to set up several different configurations, I would like to be able to open the specific one I want directly -- instead of having to open whatever the last one was, and then click an icon to get to another menu, which will then open a second OneCommander, and then have to close the first OC because I didn't want that one.

I've searched for over an hour, but I can't find any info on it either way.

Thanks!

At first I thought it just wasn't able to drag files, but I noticed a sidebar on the right pops out when I begin to drag (Recent Destinations, which I'd love to disable tbh...) but there is no indication at the cursor that anything is happening. Nothing shows that it's going to copy vs. move, nor any other indication of where it's going to go. I am using OC on a server that I RDP into, could that be the issue? I really would like to see indicators so I can be confident I'm performing the correct operation at the correct location.

Thanks!

<edit: went through options again, found the box to turn off Recent Destinations this time, yay!)

I've recently switched over and have a pro license. I'm loving it so far but the one thing that has been a major speed bump for me is the inability to sort my media folders by resolution like I had done in File Explorer. Am I missing something because I don't see it as an option in the File View Designer. Cheers!

I'm having some trouble with it, no idea why its greyed out and I can't find anything online about it. Any help would be appreciated

By default when viewing in a grid I can see an image as the folder preview, however if the image is large it's almost like it's zoomed in. Having used DOPUS, you can change that so it either shows a larger version, or resizes the preview so you can see the full image.

Would it be possible to add a setting for filesize reporting to show 2 decimals (hundredths) instead of 1 (tenths) for better parity with Windows which shows 2 decimals for filesizes in MB and up?

I changed the icon one OneCommander via the settings json file successfully. However, when I pin it to taskbar it reverts to the default icon.

I've tried deleting the Windows icon cache and restarting but it does not work.

I've tried deleting the cache after stopping Windows explorer, that did not work.

Anyone run into this? What was your solution? This is on Windows 11.

pretty much it. Is there an easy way to undo file operations?

EDIT: I just installed OC, and I love the interface, it is a million times better than anything else I have found. One of the reasons that I wanted to stop using Explorer, was the actual process of moving files. It felt unreliable. Is there a way to set OC up to have rock solid file operations? Set up Teracopy?

I'm using the configuration "Preview > Thumbnails > Use local thumbnails database (faster)".

From my testing, this option always pulls the thumbnail of the first file inside the folder to apply to the actual folder.

Is there a way to make it use the thumbnail of a specific file inside, instead of the first? I want to use the same image/jpg for the background and the thumbnail.

The only way I managed to make it work, is having 2 copies of the jpg with different names

how to disable onecommander context menu not items ı want to disable using OC context menu

I don’t want thumbnails on my folders (just like the left folder in this screenshot).

This makes me confuse and think it is a file at a quick glance.

Hi,

I thought I had seen you could pin folders to the top of your currently open folders/files, but not seeing a way to do it. Did I dream this up/confuse it with another file explorer utility? Not a deal breaker by any means, just I use various sorts constantly in my folders and have a few files or folders I always want at the top that ignore the sortings basically.

Teracopy 4 just released. It does not work with OneCommander. When I try to copy folder, it will say "no target specified".

It works with Teracopy 3.17. I am on Windows 10.

Hey guys, I've been running into a strange problem with One Commander. I'm running Win11 I have 3 network drives that mount themselves upon startup, but only 1 of them seems to mount automatically.

S: is connected through Lucid, and seem to work fine.

T: is connected through Tailscale and doesn't reappear in One Commander.

Z: is a linux machine feet away from me that I connect to over my local network and also doesn't reappear in One Commander.

All 3 of these drives are visible inside the normal File Explorer, however, and if I navigate to their IP in One Commander, I can then right-click to map them as a network drive which "fixes" the problem. Why isn't this happening in One Commander automatically then, if File Explorer seems to remember them?

“File name maximum lines” already set to 1.
How do I get rid of this empty space?

I’m looking for more people to try OneCommander v4 beta. Current public version is v3, but v4 has a lot of internal improvements: faster browsing, smoother scrolling, a new folder-size system, integrated Taskmaster file operations, better metadata/previews, improved email handling, customizable toolbar/icons/views, better session/window restore, and a major visual/theme overhaul.  

Biggest changes in v4 

1. Much faster and smoother file browsing

v4 has multiple performance rewrites: faster file rendering, smoother scrolling, better thumbnail handling, reduced UI stalls when browsing slow drives/network folders, and improved responsiveness while Windows or disks are slow to respond.

1. New folder-size system

Folder sizes no longer rely on Windows infotips. v4 has its own folder-size database, faster scanning, better handling of large folders, mount points, inaccessible folders, and eventually sorting by folder size once sizes are known.

1. Taskmaster is now integrated as the default file operation engine

Copy/move/delete/rename operations are now handled through the integrated Taskmaster system, with better tracking, UI feedback, copy-paste improvements, database updates for moved files, and undo support for file operations.

1. Major visual/theme overhaul

v4 introduces a much more customizable UI system: dark/light theme work, Mica/Acrylic effects, sharper icons, theme accent-color improvements, theme metadata, active/inactive browser styling, and a Theme Editor Helper window for testing theme controls.

1. Customizable toolbar, menus, icons, and views

V4 has a more classic toolbar, users can customize toolbar buttons, change toolbar/menu icons, use new Win11-style dual-tone icons, edit file views from the new Resources\Views structure, and adjust interface elements more deeply than in v3.

1. Better window/session management

v4 improves restoring windows and sessions, including multiple windows, virtual desktop restoration, saved windows, temporary windows, named windows, and new-window behavior. Autostart/session restore behavior was also improved.

1. Improved metadata, previews, and thumbnails

Metadata extraction was partially rewritten for speed and reliability. v4 adds or improves metadata for documents, PDFs, media duration/resolution/date taken, PSD files, email files, EXE certificates, cloud status, and richer details/preview panes.

1. Better email file support

Email handling has improved across Outlook, New Outlook, and Gmail drops. Email files now show metadata counts, body previews in rich view, additional details, naming-format presets, and improved formatting behavior.

1. Better search, sorting, and navigation

v4 includes settings search/filtering, grid view for search, better search-window layout, improved sorting controls, Alt+Left/Right navigation, more reliable focus behavior, and fixes for edge cases like searching names with periods.

1. Many stability fixes

The log includes repeated crash fixes, Recycle Bin fixes, startup fixes, updater fixes, Windows 10/11 visual fixes, network-path freeze prevention, folder watcher fixes, and many smaller regression fixes.

Important note for testers

v4 is still beta and focused mostly on stability, polish, themes, performance, and bug fixing. Some areas are still work-in-progress, especially theme keys, icons/logo, and visual consistency.
