Unity Collab CopyFile failed Error Solution

Hello everyone, today I am going to tell you about a new problem solution. Today's error is "[Collab]CopyFile failed:"

This error occurs when, even though we have deleted a file via Unity, Unity cannot detect this and throws an error when we try to upload the project to Collab. The solution to the error is quite simple.

We empty our recycle bin and then do "Assets > Reimport All". Once all assets are reimported, we get rid of the problem.

If you continue to get the error despite this process, you can comment below or if you solve the problem using a different method, you can write your solution so others can benefit. Have a nice day.
