What is a .DS_Store or ._ AppleDouble file?

.DS_Store files are created by OS X to store metadata about folders and files including viewing options, icon positions and color labels. ._ AppleDouble files are created by the OS X when an application adds resource data or metadata to a file on a disk whose format doesn't support resources or metadata.

Can BlueHarvest cause data loss?

Yes. Some applications rely on data stored in ._ AppleDouble files (for example legacy MacOS fonts or EPS files). These files will be made unusable if their ._ AppleDouble file is deleted. Always make sure you use BlueHarvest with files which don't rely on data in ._ AppleDouble files. If there are particular file types for which you don’t wish to have the AppleDouble file removed for, you can click the “Whitelist” button in the BlueHarvest preferences.

What items can BlueHarvest delete?

  • Files beginning with "._" (called AppleDouble files)
  • Files which match a UNIX wildcard string e.g "*.blah"
  • ".DS_Store" files
  • ".fseventsd" folders
  • ".Spotlight-V100" folders
  • ".TemporaryItems" folders
  • ".Trashes" folders
The last four items cannot be deleted from network servers.

When we connect to our NAS device using Windows or UNIX we see folders called “.AppleDouble”. Can BlueHarvest help?

No. The ".AppleDouble" folders are created by the NAS device not by OS X. They are also kept invisible to OS X by the NAS which sadly means BlueHarvest is unable to delete them. Please contact your NAS vendor for information on how to hide these files on all platforms.

Does BlueHarvest remove resources, metadata or DS_Store files from my startup or Mac disks?

BlueHarvest only removes resources and metadata from non Mac disks or servers. By default, BlueHarvest doesn't remove DS_Store files from Mac disks.

How can I see what BlueHarvest is deleting?

Open inside the /Applications/Utilities folder and click Console.log on the left. BlueHarvest will print a message whenever it deletes something.

What file systems has BlueHarvest been tested with?

BlueHarvest 4 has been tested with: AFP, HFS+, MacFUSE, MS-DOS (FAT32/FAT16/Bootcamp partitions), NFS, NTFS (Paragon,NTFS3G), ExFAT, SMB, WebDav and UFS. Unknown file systems are ignored by BlueHarvest.
BlueHarvest doesn’t support OpenAFS at this time. OpenAFS file systems are ignore by BlueHarvest. If you have a file system which you think is missing, use the contact form to let me know! Thanks.

Can I use BlueHarvest to clean my DropBox?

Sorry, no. It’s not yet possible to use BlueHarvest to clean a DropBox shared folder.

Can I use AppleScript to control BlueHarvest?

You can send an 'clean' AppleScript command to BlueHarvest to get it to clean a folder or volume with your current options. Example: tell application "BlueHarvest" to clean POSIX file "/Volumes/MyDisk/AFolder" The folder and all its sub folders will be cleaned.

What does BlueHarvest install?

Other than the application itself, BlueHarvest installs the following items:

(Startup Disk)/Library/LaunchDaemons/com.zeroonetwenty.BlueHarvestHelper.plist
(Startup Disk)/Library/PrivilegedHelperTools/com.zeroonetwenty.BlueHarvestHelper

These items are installed and removed when BlueHarvest is turned on/off respectively. They can safely be manually deleted.
