Question: Why does DS_Store prevent copying?

After installing ML this last week I can nolonger copy to another drive. It keeps saying DS_Store already exists. I have searched for these files and can't find them. What a PITA. What's going on with ML anyway?

Answer:
Answer:

What specific error message do you get when it fails? The absence or presence of a .DS_Store file should make no difference... you should be able to overwrite them as you desire. The error message is important for determining what's going on.


One possibility would be a permissions issue. On the external drive, do you have it set to ignore ownership? Select the drive and choose File -> Get Info.

Try checking that box if it isn't already checked.


Also, how are you doing the copy? Be specific. Are you copying a single folder, groups of folders, contents of a folder, etc? Are you copying in the Finder or using some other app?

.DS_Store files are invisible files used to manage folder-specific settings. If you try to copy a .DS_Store file into a folder that already contains one, you will be asked whether or not to replace the existing file. How are you doing the copying, and what is the specific message you are seeing? Are you being prevented from replacing the existing file, or just asked if you want to?

I simply copy folders of projects to another drive. Some files make it, some don't. I have erased as many DS_Stores I can find that are not hidden but why should I ever have to deal with this at all?


The message when it fails is DS_Store already exists in this location.

It does not ask me. It blocks the transfer.

If they are hidden, they shouldn't be copying. Are you displaying hidden files on those folders? A .DS_Store inside a folder will be copied with the folder, but if you are just copying a folder, then it won't be replacing anything and shouldn't cause a problem.


Are you merging the folders, as opposed to just copying?


How is the external drive formatted?

The drive I'm transfering from is internal 1 tera. The one I'm going to is a drive that does have a system on it but it's a Snow Leopard sys.


I'm copting a file folder with 10 file folders of music projects.


I'll try and select the ownership ignor button if it's there.

Hey, Thomas,


I faced same problem, but, I can't find the box of "ignore the ownership on this volume" on my MacPro, I am using OS X 10.8.2 running on MacPro with 15" retina display, simplified Chinese version. Can you help to provide some hints? thanks.

That check box will never appear on the drive you are starting up to. It would be impossible for OS X / UNIX to operate correctly on an unmanaged drive. You can only turn it off for other drives.

Hi, Kurt,


Thank you for your reply.


I attached two external harddrives by USB to my computer (running on OS X 10.8.2), and I want to copy many files in a folder from a drive to another, but failed for it keeps saying DS_Store already exists.


It doesn't work no matter the target drive is formatted as exFAT or FAT32 or Mac OS format. (the source files are located in an external harddrive formatted as exFAT)


Is there any way that I can copy huge volume of files from one external harddrive to another external harddrive? thanks.

It should work without ever mentioning the .DS_Store file. Since it's normally hidden, you can't select it. Therefore, it can't be part of the files you're copying to the other drive. Is the following true?


You can actually see the file .DS_Store in the folder you're copying from. In which case, you should see it on any drive, and in any folder, along with other hidden files and folders which shouldn't be visible.

Kurt,


I removed all those .DS_Store files and copy again, it works. I think this may caused by I was using Mac OS, Windows, and "Windows under virtual machine" to access that external harddrive, different kinds of hidden files created by different systems may create problems. Thank you.

"Windows under virtual machine" to access that external harddrive

From Windows you would have that problem. OS X / UNIX hides any file that starts with a period. Windows doesn't give a hoot about the leading period and just considers it part of the file name, so you will see them in Windows.


Bit of a guess, but when you try to copy them from Windows, the permissions of the .DS_Store files are likely preventing you from overwriting, or copying them to the external.

I'm having this problem too!
Both when I try to copy files to an external drive, AND when I try and copy documents and folders onto another location on my mac's INTERNAL drive ! Weird.

I hope somebody can help, this is frustrating.

I started another thread about this issue a while ago, and still nobody has been able to offer an effective solution which does not involve a certain risk of me losing my data !
