How to fix "The Finder can’t complete the operation because some data in “filename” can’t be read or written. (Error code -36)"

The "cannot be read or written" error code (-36) is a file system error that occurs when an attempt is made to read from or write to a file that cannot be accessed. This can happen for a number of reasons, including but not limited to:

• The file is corrupt or damaged.

• The file is in use by another program.

• The file is not compatible with the operating system.

• The file is not properly formatted.

This error can be frustrating because it can prevent you from accessing important files. However, there are a few things you can try to fix the problem.

• Restart your computer. This will close any programs that are using the file and may allow you to access it.

• Try accessing the file from a different program. If the file can be opened in another program, it is not corrupt.

• Check the file format. Make sure the file is saved in a format that is compatible with your operating system.

• Update your software. Outdated software can sometimes cause problems with reading or writing files.

If you are still unable to access the file, you may need to contact the software manufacturer or your IT department for help.
