I put the Mac system on a 128G SSD SSD, the results found that my User name folder has more than 20 g of unknown files, but also show that I would like to save some space on the SSD, I would like to use these potentially useful files to my 250G mechanical hard drive.
Enter "Go to Folder" via Shift+command+g [~/library/application support], go to this hidden folder, a sub-folder to look over, Found the culprit is a folder called Mobliesync itunes Backup iphone, and then started to move on.
Backing up iphone files is still useful in case of white apples. You need to build a soft connection to transfer. Then I made a difficult order to build a soft connection, and it was strange that the basics were too weak.
First copy the backup folder under this Mobilesync folder to my mechanical hard drive, the address I copied is the Mobilesync folder of the Macintosh HD hard disk, and if you copy a different folder, you need to specify your path in the following command.
Then delete/users/your user name/Library/Application Support/mobilesync under the backup folder
After opening the terminal, enter the following command:
"Ln-s/volumes/macintosh\ hd/mobilesync/backup/users/your username/library/application\ support/mobilesync/backup"
Use this command to soft-connect the original backup to the address on the new mechanical hard drive. The ln-s command means that the format is "the address of the Ln-s source folder link" where the source folder is the actual storage of the data, the linked address is just a shortcut, but is synchronized with the changes to the source folder, and almost no disk space is consumed.
I have encountered two difficulties in this:
1, with the CD Application Support command to enter the folder to view the time always remind me that the folder does not exist, through Baidu only to find the original folder name with a blank folder when you need to add a "\" in front of the space, so a command becomes "CD application\ Support "This way of writing, the Ln-s command of the folder is also the expression of this method.
2, the other disk's letter how to express. Unlike the C and D drives in Windows, the Mac is displaying all of the hard drives in the/volumes folder, so "/volumes/macintosh\ HD" represents a mechanical hard drive that I call Macintosh HD.
OK, so that's the end of the transfer, emptying the Recycle Bin, SSD on the empty space of more than 20 g, the joy.
Thanks to the following various answers provided by Baidu to provide me with a solution, but also ashamed of their lack of technical knowledge, so that the resolution of the great God to apply to their own computer on the different folders on the crime, so can not divert, and to know the command of the grammar and expression norms.
