Predefine Open/Save window size?

mikolajek · 04 Dec 2016

For years I've been using DirectFolders to get a predefined size of almost all dialog windows, especially Open/Save ones, but not only. It was also capable of enforcing the predefined file list presentation which I enjoyed.

What I've been observing though is that DirectFolders is less and less effective in Windows 10. Of course one thing is that the program is apparently no longer developed but the other - I believe - is that Windows' internals have been changed and it no longer supports the way dialog windows are generated.

Regardless, are you aware of any app / trick that would make it possible to set the fixed window size? I know that many applications do remember window sizes (at least for a while), but this "memory" is not that reliable I'd like it to be.

Hi, I don't know of a program, but this registry key
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\CIDSizeMRU
holds values 1 per program whose "common item dialogue" box (open/save box is old terminology, strictly speaking) size has been changed. For example, this value represents Firefox as you can see.

So I suppose if you wished to set all to default, you would delete all these values.
You'd need to test that carefully.

Conversely you might be able to work out a way to set the size for particular programs.

==================
Increasing the dimensions by 25% (using FileBox Extender) suggest these parameters change:

Here's the whole registry change which occurred when I made that change:
