What Is the File Extension ACD?by Lisa Henshall
The file extension ACD is associated with files created with two different programs. One is ACID Project file, the program most commonly associated with this file extension. The second is RSLogix 5000, a program used to create and maintain Rockwell Automation Logix platforms.
Opening .ACD Files
If your Windows-based PC or Mac is unable to open .ACD files, you may not have the appropriate program installed or you may have file extension-related registry errors. Registry errors can be fixed manually or via a registry cleaner. Visit download.com to find a free or inexpensive cleaner.
Sony ACID Pro is an audio production program. These files generally contain audio tracks, loops or other files used within a project, such as sound effects, volume and pan adjustments.
About RSLogix 5000
RSLogix 5000 is used to work with other Rockwell Automation Logix platforms, and includes information and instructions about controllers and processors. ControlLogix, CompactLogix, FlexLogix, SoftLogix5800 and DriveLogix systems are part of this group.
Where to Find Them
Some electronics or computer stores will have copies, as will many university and college bookstores. To purchase online, go to www.rockwellautomation.com for RSLogix 5000 or www.sonycreativesoftware.com for ACID.
Open Odd Extensions
Several tricks exist to look at files with mystery or odd extensions. Windows users can press "Shift," then right-click on the .ACD file. Mac users can click the file, then press "CmdI." On both systems, you can then look for "Open with" in the pop-up menu and choose a program from the list.
If you need to open just one file or if you prefer to test a program before purchasing it, you can try a free trial. For RSLogix 5000, visit rockwellautomation.com to download a 30-day trial of the software. ACID trials are available at sonycreativesoftware.com.
