아이폰에서 두대의 PC에서 음악수동관리

아래내용을 따라 해도안되시는 분은
그냥 처음동기화 시킨 PC 의 설정파일을 덮어씌우시면 됩니다.

다만 집 pc / 회사 pc 설정(폴더등등)이 틀리기 때문에 다시 잡아주어야 하는 부분도 있습니다. 
그리고 응용프로그램도 다 없어져 버리네요
저는 다 수동관리하니깐 상관없는데 참고하세요

설치된 아이툰스 폴더에 가면 저렇게 파일이 있습니다.

또다른 음악수동관리를 하고싶은 컴퓨터에 위의 설정파일을 덮어 씌웁니다.



아래는 두대의 pc의 키값을 똑같이 만들어서 동기화 하게하는 방법입니다.

How to sync an iPhone with two (or more) Computers

Backup Your Library

On the machine you want to sync with, backup "iTunes Music Library.xml" and "iTunes Music Library" (Tunes Music Library.itl on PC) to a safe location. These are the files you will be modifying.

1) Find your iTunes Library ID

On the machine your iPhone currently syncs with, open "iTunes Music Library.xml" with a text editor and find the entry between the <string></string> tags, after "Library Persistent ID". In the example below this is 8B6C633F7DACB74B. Copy this entry exactly to a piece of paper, email, temporary file etc. You can then close this file.

2) Change your Library ID

iTunes stores your library information in two places. An XML file and a binary file. You now need to change the ID in both so they match your other library.

Make sure iTunes is not running.

On the machine you want to sync with open "iTunes Music Library.xml" in a text editor. Again, find the entry between the <string></string> tags after "Library Persistent ID" and copy this entry exactly. This time you can use the clipboard if you wish.

When you have a copy, replace this entry with the one you copied in part 1. Make sure you do not change anything else, and the length of the entry is 16 characters/digits. Save this file and close it.

In the Hex Editor, open "iTunes Music Library" (Tunes Music Library.itl on PC).

Select "Find and Replace" from the Edit menu. Make sure "Hex" matching is selected (not ASCII). In "Find" enter the ID you took a note of in Part 1. In Replace, enter the ID you copied at the start of Part 2. Choose Replace All, there should be one match.

Save this file and close it.

Success!

Start iTunes on the machine you wish to sync with and plug in your iPhone. When you select "Manually manage music and videos" you will no longer be prompted to erase your data, nor will the files on your iPhone be grayed out
