Published by Nyau Wai Hoe - Updated on

If you’re using Windows 11 or Windows 10, you’ve probably come across different files and processes. Some are familiar, others, not so much. One of these is CoreSync.exe. It’s actually a part of Adobe Creative Cloud responsible for syncing your files across different devices (if you have multiple devices using Adobe products with the same account). But sometimes, it might cause errors like “Application Error” or “System Error“.

In this guide, we’ll talk about what CoreSync.exe is, if it’s something to worry about in terms of security, what errors it can cause, and how to turn it off or get rid of it if you need to.

What is Adobe Core Sync (CoreSync.exe)?

CoreSync.exe belongs to Adobe Creative Cloud and is made by Adobe Systems. When you see a file ending with .exe, it means it’s a program that can run on its own.

Adobe Creative Cloud gives you a bunch of apps and services for things like graphic design, video editing, and more. CoreSync.exe is key for making sure you can get to your Adobe files no matter where you are, as long as you’re online. It handles the syncing, so it’s pretty important for anyone using Adobe Creative Cloud.
