Look - I'm a Mac user, forced to use Windows. I have a great Mac tool called Pathfinder. Well, it doesn't work on windows, so I found DO, and thought this was the windows version of Pathfinder. I bought two full copies for all of my computers.
I've been using it for 6 months. Most times I ignore it's performance, but lately, it's gotten to be flat out unusable. I can't stand it! I've Literally spent the last 20 minutes waiting for the app to "respond" so I could close a tab.
Sure, I open tons of tabs... yes, I'm opening remote windows shares, yes, they are over a VPN... so, am I pushing it hard??? Yep.
But, I don't expect it to just "freeze" for many minutes at a time. I don't expect to sit there starting at a DO "wait cursor", then open the dumb old windows file manager, and navigate to the same folder, and have it load in "a few seconds", only to stare at the DO wait cursor for 15 seconds longer. This last bit -- that is UNACCEPTABLE. The stupid free file manager should not perform 10x better than the fancy paid tool!!! If it does, then why would I ever recommend the paid tool!!
Okay, I'm pissed -- as you can see. Now, frankly, I want to be WRONG I want someone to tell me I'm using it wrong and all of these issues are my foolishness... I will be wrong all day, if I can just figure out how to make this work.
If not, what is another "windows" file manager that has some decent (i.e. dual pane, multi-tab) capabilities.
Shares over VPNs can be so slow that they're barely functional in any software. It's made worse the more information you are displaying, since that can result in more round-trips to the server to request the information for each file/folder, and each round-trip can take 5 seconds (from logs we've looked at in the past) instead of a few milliseconds as on a normal local drive or network share over a typical LAN.
You can speed things up a bit by:
Turn off the folder tree.
Turn off columns which show anything other than Name, Size, Date.
Turn on Preferences / Folders / Folder Display / Show generic icons for... Network Drives.
Use Preferences / File Displays / Border / Display as a static header, for a simplified path bar.
Less likely to be needed, unless you've customised things a lot: If you've set up any complex labels/filters that check file content or metadata, turn them off or add rules to stop them from looking at things on the involved servers.
That may make things less bad, but you'll probably still find them slow, because network shares over a typical VPN are inherently slow, and the protocol Windows uses for them just wasn't designed for that scenario. You'll find them slow in File Explorer as well, although it does less so they won't be as slow as a default Opus setup.
I believe what hes asking for is the UI to remain responsive while a network share / folder is loading. That way a user can still perform some operations, like closing a tab, that would not require access to the data currently being loaded. I'm going to take an educated guess and say that's something complicated to do though.
You can usually open a new window to do other tasks, at least. It's unusual for the whole program to be blocked, rather than just a window.
We have made improvements to this and try to make things not hang the UI while waiting for filesystem requests, but it's easier said than done, and network shares over a high-latency VPN are never going to be a pleasant experience in general, in Opus or anything else.
