Support and Feedback / Re: Increase RAM/resources available to Multi Commander

« Last post by Mathias (Author) on June 16, 2026, 22:38:13 »

It a bit unspecific. so hard to say why you see that. Most work that require CPU are run in background threads.  not sure what pauses you mean, I have not notice anything like that. There should not be anything that cause pause.. Often when things like that happen it is because MC wait for some call from Windows. or external 3rdparty software like security software or other software that hook themself into other processes. that hijack calls from MC to windows.

No. There would be no point in MC to allocate more memory then it needs. MC it will cache and reuse memory it already have got.

Support and Feedback / Increase RAM/resources available to Multi Commander

« Last post by whiskytechfred on June 16, 2026, 22:19:31 »

Hello,
I really enjoy using MC because of all it's configurations and amazing UI.  However, it often "pauses" or "redraws" the UI.  I won't say hang as I don't get any warnings or hung interface, it's just that either the interface doesn't register mouse commands (pauses) or the UI redraws several times in a row.
I have a fairly high end machine, Ryzen 9 9950x3d with 192Gb RAM, plugged on ethernet at 10gbps and paired with ab AMD RX7900XT so I was wondering if there's a parameter that I can set to allocate more RAM or a higher priority to MC (and if doing that would help with these issues).  On the docs/troubleshooting-hang page from the MC website it's written that
Cache settings: Optimize for your system
Memory limits: Configure for available RAM
but I can't find these settings in the configuration pages.
I used to work with FreeCommander and I don't recall having such issues in that app.
Thanks in advance for any hints you may be able to provide,
Fred

Support and Feedback / Re: Troubleshooting Custom Icon Deletion When Adding New Extensions Custom File Type

« Last post by total_annihilation00 on June 15, 2026, 09:26:05 »

Adding extension again will remove the icon override for that icon
 BUT only in the memory. it actually does not save the IconOverride.xml files.

But since you are modifying the icons override before starting. it will recreate that file.

So until fixed, Restart before adding more icons to override.

Thank you Mathias, you're the best !

I can't reproduce that

I add a override icon for PDF
restart
Add a run/open for PDF so it opening PDF
Save
restart

Both works.

Might be in what order things are done that trigger some bug? So instead of me trying to figure out exactly what combination of order of things, Can you give me steps to reproduce it since you can reproduce it ? The order you are doing things to trigger it.
Having a step by step list on how to reproduce it will make it easier to figure out why it is happening

It's easy, make an Icon Override (custom Icon). then make a File Extension for it in Launchers (Run/ Open), then modify it a 2nd time by adding an extension: the custom Icon Override will disappear ! The trick is the second time you add another extension to the Launchers Extension List (re-modifying it, not the 1st time), it causes the deletion of the Icon Override !!

What I'am trying to say is after you make a PDF extension in launcher it will work, but if you were to add *.azw3 or any other extension a *Second* time and click Save to update it, the Icon Override gets deleted !! The 1st time it doesn't cause issues, but it won't let you add a 2nd extension without breaking the Icon Override for PDF.

Do this and you will see:
I add a override icon for PDF
restart
Add a run/open for PDF so it opening PDF (launcher will look like: "*.PDF")
Save
restart
Now Add a 2nd extension alongside the PDF (call it anything let's say *.azw3) and click Save: the Icon Override for PDF disappears !!! (launcher will look like: "*.PDF *.azw3")
Check Icon Override (will be missing) This happens for every entry of Icons and their Launcher Extensions not just PDF. Worst part is you will lose all re-modified extensions for the Icon Overrides listed in Launcher Extensions. So if I had Icon Overrides for "*.PDF *.EPUB *.MOBI" those will *all* get deleted when you hit Save a *Second* time.

Please Mathias, this is a nasty bug, I need it fixed badly. I won't take your time unless it's important !

Why does the Icon Override get deleted when I modify an existing File Extension in launcher (Run/ Open) ? This is clearly a bug ! I'am unable to use custom Icons and then change the extension of a Launcher Run/ Open because of this flaw ! Can you please fix this ASAP ? I need to customize some Launchers and Icon Overrides but the the Icon overrides are being deleted…

« Last post by ncnnnn on June 13, 2026, 04:09:25 »

I clicked the refresh button on the file list, which is on the right. The problem is, I first clicked a node in the folder tree, and then immediately clicked the refresh button on the file list. Then it refreshed the folder tree and collapsed several expanded folder nodes, only keeping the current one.
