Open the program from the Windows menu. Then drag the folder you want to customize onto it, or right-click a folder in Explorer and select CustomFolder.

In the top panel, click the Personal icon panel button to open it. It shows the icons you have already added. To add new ones, simply drag them onto the panel.

Z and X — switch to the previous/next icon style.
C — change the color palette.
V — rotate the icon.
Space — toggle color selection between primary and secondary.
F — open/close the Folders Panel.
T — change the theme.

There are 4 ways to select colors:
— From the color wheel
— From the palette
— From saved personal colors
— Entering the RGB values manually

When the primary color is active, any color you pick is saved as the primary; the same applies for the secondary color.

Open the icon panel and click the desired icon — it will be applied to the working folder.

Open the icon panel and drag the folder whose icon was customized with CustomFolder onto the panel. The icon will be added to your personal collection — click it to apply that design to the working folder.

Drag a JPG image onto the icon previewer — it will be applied as the icon's background.

Music folders are folders that contain a folder.jpg file inside — Windows partially displays this image on the folder. Dragging the folder onto CustomFolder automatically loads the album cover as the icon preview. Click Apply to save the custom icon.

Move the mouse over one of the personal color slots and scroll the mouse wheel to save the current color to it. To delete a saved color, right-click the slot.

Open the Emblems Panel (button 4) or the Floating Emblems Panel (button 5). In the emblems panel, select an emblem and a position, then click Add. In the floating emblems panel, select an emblem and drag it to the desired position, then click Add.

Open the emblems or floating emblems panel and drag a PNG image onto it — it will be added to your collection immediately.

Emblems must be 85×85 pixels for fixed-position use (up to 9 per icon). For floating emblems, 128×128 pixels is recommended, with a maximum of 160×160 pixels.

Standard-size emblems are shown normally. Larger emblems appear at the same display size but with a gray background and a white dot in the top-right corner. When used as a fixed emblem, they are added to the icon at their actual (larger) size.

Click the Folder Panel button to open a panel where you can drag all the folders you want to apply the same design to.

You can remove folders one by one or click Delete to clear the entire list. Once the design is ready, click Apply in the folder panel to apply it to all listed folders.

This happens when you select an emblem and position in the emblems panel — it shows in the preview — but it is not fixed to the design until you click Add.

Press the T key on the main screen (the emblems and icon panels should be closed). CustomFolder has 8 themes to cycle through.

Click the Color scheme button in the toolbar.

Select the target folder first (see question 1), then click the Default Icon button to restore the standard Windows folder icon.

Use CustomFolder in portable mode. This can be enabled from the Configuration Panel.

Open the Settings Panel and enable the Rounded edges option.

Click the Open Gallery button. It opens a page showing all user-created icons, icons from your personal collection, and your emblems collection.

Click the same button used to open the panel, or click the close icon on the panel itself.

Open the Personal icons panel or the Emblems panel, then right-click the icon or emblem you want to delete. You will be asked to confirm the deletion.

If the dialog has focus, press Esc. You can also click anywhere on the main window body to close it.

Some Windows updates have caused custom folder icons not to display when the folder is on a network drive. You can find instructions on how to fix this problem here.

This is generally solved by rebuilding the Windows icon cache. You can find instructions on how to do it here.

The following steps describe a scenario with two computers (A and B), both using OneDrive.

Computer A
On your local OneDrive, select the folder and apply a design with CustomFolder. Then right-click a free area of the CustomFolder window, select Synchronized folders, and drag your folder into the panel. Share the folder with the user on Computer B — it will upload to OneDrive.

Computer B
The user opens OneDrive online, clicks Shared, finds the folder, right-clicks and selects Add shortcut to My files. OneDrive will download the folder to the PC. Open CustomFolder and add the folder in Synchronized folders as described above.
