How do I resolve 'Error code -36' when copying a folder in Finder on Mac?

While copying data from desktop to a hard drive - there is constantly a message that the Finder can’t complete the operation because some data in can’t be read or written

Error code -36

If I do it copy each file seperately then there is no problem but if I copy the whole folder there is an issue

Cannot copy/paste folder, get Error Code -36 I cannot copy/paste a folder on my new iMac 24 running Ventura 13.2. I can move a folder from Documents to the Desktop; but if I do a Copy and Paste for the same folder, I always get an Error Code -36 message. This is true for any folder containing jpg, docx, xlxs, m4a, etc. files. It also happens when trying to copy to a flash drive. It also happens with an empty folder. I can copy/paste individual files with no problem; the problem only occurs with folders. I have worked with five different Apple tech people trying countless things over the last month; they have watched it happen. Nobody has come up with a solution or fix. I have a MacBook Air running the same software, and I am able to copy/paste on it. Any ideas?

error code -36 Dear community, I am aware that solutions to "error code -36" have been asked multiple times, but the behavior I see is different from what I could read so far, so I am opening this topic. Precise error: The Finder can’t complete the operation because some data in “” can’t be read or written. (Error code -36) just as a note: there is nothing between “” in the error. I am copying some (sub-sub) folders under my Documents to another location contained in Documents. No external drives involved. If I try to copy the folders containing files, "error code -36" appears. If I try to copy the files contained in the folders, no error. Multiple files, also no error. If I try to copy even an empty folder, the error appears. If I create a new empty folder and I try to copy it to the second location, the error appears. If I move the folders, no problem at all. Just for now I am creating new folders and sub-folders in the location I need and I am copying the files. Besides being this method "quite less practical" than Command+C Command+V... I would like to solve the issue. Never experienced this before. The only recent activity that come up to my mind is the update the OS to Monterey 12.5.1 a couple of days ago. So far I tried as solutions, as suggested here around, as solutions: . starting the Mac in Safe Mode -> same behavior . Run Dot_Clean command from Terminal Any help will be appreciated, Thank you!!

-36 Error is an I/O Error and is typically caused by a hardware failure of the drive.
