.ACS3 File Extension
What is an ACS3 file?
An ACS3 file is a skin file used by version 3 of AIMP, a Windows music player. It contains a skin that can be applied to the player's interface. ACS3 files include layout information for panels, containers, border colors, text colors, and fonts.
To add a skin to your AIMP player, place the ACS3 file in the C:\Program Files\AIMP3\Skins directory. Then go to Skins in the AIMP application, select your skin, and click Apply.
NOTE: The ACS3 file replaced the .ACS2 file with version 3 of AIMP. The ACS2 file can still be opened by version 3 of AIMP.
