OPEN FILE window too small. How to change default

Since installing Big Sur, all my "open file" windows come up too small. I need to see a little more of my favorites and saved folders list.

Is there a way to change this default size...no I don't mean drag the corners each time.

Below is perfect example when looking for a library to open in FCP.

You can try >System Preferences>General make changes

If that does not do it— change display resolution

>System Preferences>Display

or

See >System Preferences>Accessibility

You can file a bug report here—Apple Feedback http://www.apple.com/feedback

You have to increase the size off the overall Open window a bit before you an increase the width of the sidebar:

However, the resize isn't remembered and it has to be done every time. Tell Apple what missing features you'd like restored or new features added to the system via Feedback - macOS - Apple.  

That was a standalone demo of how the NSOpenPanel should look. It has nothing to do with your daily applications that were compiled with the Apple AppKit library that uses the NSPanel => NSOpenPanel/NSSavePanel classes whose size settings are borked. As I said, Apple will have to issue a fix for this in an update to macOS 11. The sooner the better.

No. Apple must provide a future update of Big Sur to fix this goof on their part. Until they do that, you have to rubber-band the Open dialogs every time, because the controlling application will not remember the resize. The Favorites panel can be interactively resized with the same caveat.

The following AppleScript/Objective-C script shows the programmatic usage of an NSOpenPanel that applications use to open that dialog. In this case, and unlike Apple, I have set the correct frame size for a normal window.

Press control+command+R to run the following code after it has been copied, and pasted into the Script Editor.

use framework "AppKit"
use framework "Foundation"
use framework "OSAKit"
use AppleScript version "2.4" -- Yosemite or later
use scripting additions


property NSThread : a reference to current application's NSThread
property NSString : a reference to current application's NSString
property NSURL : a reference to current application's NSURL
property NSArray : a reference to current application's NSArray
property NSOpenPanel : a reference to current application's NSOpenPanel

property HFS : "HFS"
property POSIX : "POSIX"
property default_location : "~/Desktop"
property file_types : {"com.adobe.pdf"}

if not (current application's NSThread's isMainThread()) as boolean then
	display alert "This script must be run from the main thread using cntrl+cmd+R." buttons {"Cancel"} as critical
	error number -128
end if

# choose POSIX, or HFS for returned file format
set openstuff to files_folders(HFS, default_location)
display dialog openstuff with title "Selected Stuff"
return

on files_folders(afmt, this_location)
	
	set this_location to POSIX path of this_location
	set this_location to ((NSString's stringWithString:this_location)'s stringByStandardizingPath()) as text
	
	set z to NSURL's URLWithString:this_location
	set these_types to current application's NSArray's array()
	
	set oPanel to NSOpenPanel's openPanel()
	tell oPanel
		its setFloatingPanel:true -- over the top of all other windows
		its setDirectoryURL:z
		its setFrame:(current application's NSMakeRect(0, 0, 830, 580)) display:yes
		its setTitle:"Open"
		its setMessage:"Select additional file(s) and/or folder(s) with ⌘"
		its setPrompt:"Open"
		
		its setAllowsMultipleSelection:true
		-- its setAllowedFileTypes:types
		its setAllowedContentTypes:these_types
		its setCanChooseFiles:true
		its setCanChooseDirectories:true
		its setTreatsFilePackagesAsDirectories:false
	end tell
	
	set returnCode to oPanel's runModal()
	if returnCode is (current application's NSFileHandlingPanelCancelButton) then
		error number -128
	end if
	-- set the POSIXpaths to (oPanel's |URL|()'s valueForKey:"path") as list
	if afmt is "HFS" then
		set the HFSpaths to oPanel's URLs's valueForKey:"_osa_hfsPath"
		set txtStr to HFSpaths's componentsJoinedByString:return
	else if afmt is "POSIX" then
		set txtStr to ((oPanel's filenames)'s componentsJoinedByString:return) as text
	else
		-- neither is not an option, force user cancel
		error number -128
	end if
	return txtStr as text
end files_folders

You copy and paste that entire code into Apple's Script Editor. The control+command+R compiles and runs it to produce an Open file panel. Tested on macOS 11.1.
