High RAM usage - ARM64 Surface Pro 11

[Razorback2000]

Hi there.  Memory usage is very high on MS SurfacePro 11 (ARM64). 

OC version is 3.108.0.0.

I saw an old thread from 2024 that mentioned this but it hasn't been resolved.

thanks.

I have not tested it on any of the ARM64 machines but the program itself it shouldn't leak memory. This is likely one of system thumbnail/preview handlers. 

Due to way of these work, they get loaded into the calling process (OC) and then whatever memory they don't clear, become the bloat contributed to calling process (OC).

That is hard to find, but with something like  https://www.nirsoft.net/utils/shexview.html you could disable some handlers, or notice which filetypes you preview or view thumbnails from. Most likely some picture viewer you have has replaced system image preview/codec.

There is an ARM version now (portable only; run from a new folder)
https://onecommander.com/OneCommander0.0.44.0.zip
It needs .NET10
I only tested if briefly on first SurfaceProX SQ1 and it reported as running as ARM64
