Author Topic: IDEA: Drag and drop folder icon replacer (Read 52,671 times)

Rockets · « **on:** July 17, 2016, 10:56 PM »

First, a little bit of theory. What happens when a person sets a custom icon for a folder in Windows 7?
1. Attributes of a Folder change to Read-only (of the folder, NOT content!).
2. A hidden system file desktop.ini created inside that folder, which contains a link to the icon.

Possible app:
1. drag n drop folder
2. drag n drop icon
3. icon is copied to the folder, desktop.ini is created. ini and ico set hidden

desktop.ini content:
[.ShellClassInfo]
IconResource=mynewshinyicon.ico,0

or

[.ShellClassInfo]
IconIndex=0
iconfile=mynewshinyicon.ico

If I'm not mistaken, it's not the read-only attribute that's important; it's the System attribute that is necessary.

I can easily adapt my "MT Icon" Coding Snack for this.

Rockets · « **Reply #2 on:** July 17, 2016, 11:22 PM »

That was a fast reply, I added "hidden" to 3.

Rockets · « **Reply #3 on:** July 17, 2016, 11:39 PM »

I tried MT Icon. I like it, could u also modify it to change icon for all subfolders? Regardless empty or not. Like adding * to allowed filenames.

You were right:
The desktop.ini should have the attribute of system, and the folder containing it also needs to have the attribute of system for it to have an effect.

I can whip an app up like this if you still interested.

Cool idea! I guess you could also make an option where the ico file would also be copied to the folder, thus making it a "portable" folder.

I have this almost ready to go. Just took some slight modifications to an app I had already written.

Well, he'll have a choice! I'm just about to upload my app.

Drag/drop a folder and icon and press Go!

it seems just what I need, is it possible to keep .ico file name? And make autoclose optional, please.
If I drag and drop the first time, everything is OK. If I drag and drop the same folder 2nd time, it doesn't work. Browse works.

Some icon changer apps write IconResource and not IconFile.
If there are both IconResource and IconFile in desktop.ini, IconFile is ignored.
It would be better to replace
IconIndex=0
iconfile=mynewshinyicon.ico
with
IconResource=mynewshinyicon.ico,0

Please add * (include all folders, empty and not) option to "MT Icon". c.gingerich's FolderIconDrop works well!

c.gingerich · « **Reply #11 on:** July 18, 2016, 07:12 PM »

Update to 1.1

Added icon index option
Optional auto-close
Optional auto-clear

Added icon index option

it still uses:
IconFile=XXX.ico
IconIndex=0
can you replace these 2 lines with:
IconResource=XXX.ico,0
?

.ico file is not hidden anymore, desktop.ini is.

If I add folder where I already changed icon with FID, drag n drop still broken for this folder.

c.gingerich · « **Reply #13 on:** July 18, 2016, 08:22 PM »

Fixed the folder drag/drop bug and the hidden icon. I added xxxx.ico,0 for the resource but also left IconResource=0 as that is what Win 10 uses. if I use xxxx.ico,0 on my system it doesn't work. Can anyone else confirm that?

confirmed, win 10 home. It seems I have to reedit all my desktop.ini files if I upgrade my main PC to Win 10. I am on Win 7 now.

I added xxxx.ico

don't see it
can you make it optional what to use?

One more problem, how can we refresh icons cache in Win 7 and 10? Rebuild Shell Icon Cache doesn't work for me

confirmed

unconfirmed. IconResource is working under win 10. What permissions does your app set?I will try to understand why.

PS: Windows 10 doesn't refresh icon folder everytime. I will try to find any solution.
Found this:

Use a shell function that will notify all running Explorer windows to use the updated desktop.ini. This API is exposed in VBScript via Shell.Application.NameSpace("folder\").MoveHere:

Code

@echo off
for /r %%I in (*.ico) do (
    attrib -h -s -r "%temp%\desktop.ini" >nul
    (
        echo [.ShellClassInfo]
        echo IconResource="%%~nxI",0
    )>"%temp%\desktop.ini"
    attrib +h +s "%temp%\desktop.ini"
    (
        echo set shell = CreateObject^("Shell.Application"^)
        echo set folder = shell.NameSpace^("%%~dpI"^)
        echo folder.MoveHere "%temp%\desktop.ini", 4+16+1024
    )>"%temp%\updateIcon.vbs"
    cscript //nologo //b "%temp%\updateIcon.vbs"
)
pause

P.S. I forgot most of VB so whoever remembers it may rewrite the entire code in VBS (embedded).

How can I run this code?

Apologies for the delay; here's my offering: FolderIconTool

Rockets · « **Reply #18 on:** July 18, 2016, 10:36 PM »

I tried under Win 7 and 10 to change folder icon with right click-properties-customize-change icon

Windows writes in both cases IconResource=XXX.ico,0, so we can delete
IconFile=XXX.ico
IconIndex=0
completely. It is not needed at all.

Does it really matter if it's there or not?

FolderIconTool

If it is not hard for you, please replace
IconFile=XXX.ico
IconIndex=0
with
IconResource=XXX.ico,0

Quote from: skwire on July 18, 2016, 10:38 PM

Does it really matter

IconResource=XXX.ico,0 has more priority, if desktop.ini already has it, IconFile will be ignored.

Please re-download and see if this version works as you desire.

if this version

It seems perfect now. The last problem is not so important:
we have to say windows explorer to refresh folder's icon. If a folder already had an icon, it takes forever to see the new one.

PS: c.gingerich's app uses the whole window for drag n drop and automatically detects where ico and folder should go, so it is more convinient on a touchscreen.

It's always really fun to see threads like this.

And it's my duty to remind everyone reading these threads to consider sending a little donation to the coders to say thanks (skwire and c.gingerich in this case); just click on the yellow dollar signs under their names.

c.gingerich · « **Reply #24 on:** July 18, 2016, 11:29 PM »

I'll update mine tomorrow and see if I can build in rebuilding the icon cache.

@mouser thanks!
