1, the most common case: iTunes synced video and audio files are lost.
Analysis reason: Due to USB interface and other reasons, iTunes synchronization sometimes fails, and video and audio files will suddenly disappear. Sometimes synchronization will come back, sometimes it won't. At this time, in terms of capacity, the video and audio capacity of iTunes will decrease, and correspondingly, other capacities will increase. Our aim is to find those lost files and delete them.
Cleaning method:
/private/var/mobile/media/iTunes _ control/music directory for storing multimedia files (such as MP3 and MP4) uploaded by iTunes. The files have not been modified, but their names have been modified. You can download it directly to your computer and read it. Folders that all start with "f", such as F 1 1, F20, etc. Step: delete the folder starting with f → restart the machine → cancel multimedia synchronization → synchronize again.
2.iTunes failed to sync photos.
Analysis reason: For unknown reasons, iTunes will not be able to synchronize pictures and photos. At this time, the pictures and photos originally stored in the iPhone5 can't be found. In fact, the files exist. The photo file is in the/private/var/mobile/media/photos/thumbs folder of iPhone5. If you have pictures in your PC and don't want to keep them in iPhone5, you can directly delete all the files in your thumb and the photo database files at the same level as your thumb. If you still need these pictures, but the PC doesn't have them, then you can only copy the ithmb files in the Thumbs folder to the PC and decompress them with Format Factory software (Factory.exe searched many download links in google).
Cleaning method:
Find the directory/private/var/mobile/media/photos/thumbs, delete the folder starting with f → restart the machine → cancel multimedia synchronization → synchronize again.
3. Installed programs cannot be cleanly deleted.
Reason for analysis: The official installation is of course the ipa file of iTunes, the third-party installation programs such as Cydia (including deb), and the App is directly copied and pasted. Although iTunes, Cydia, etc. You can delete it through your own program, and sometimes it is not clean. The most common method is to install different versions of the same program with these programs. Sometimes you will find that everything can be installed, but there is only one iPhone5, and you forget how many times you installed it. What versions are there? In this way, there is more and more garbage in iPhone5. In this case, you can only enter the corresponding folder and open it for search.
Cleaning method:
① ipa is installed in the/private/var/mobile/applications folder, and the installation date can roughly determine where the software is.
② Cydia, 9 1 assistant, is manually installed in the folder/private/var/stash/applications, and the folder name here is clear at a glance. Find the software you also want and delete it directly. The premise is that you deleted it once on the iPhone5, but it was not completely deleted, that is, you found a piece of software that you have deleted in these folders, but you still have its folder.
(3) Files/directories of/users/media/applications can be safely deleted, including software compressed packages with errors deleted.
(4)/tmp newly discovered files that iTunes failed to synchronize or delete, and folders named after the type of install_greenmile. XXXXXX, delete.
⑤/user/media/publicstage 6.14 Redundant file path of iTunes installation failure.
4. The files in the file management software have not been cleanly deleted or left in the recycle bin (actually not deleted).
Analysis of reasons: such as Mobilestudio file management software. You can delete, copy and paste and change the name in Mobilestudio. But Mobilestudio has a recycle bin, and all the deleted files are in the recycle bin. If you don't empty the recycle bin, the files will still be in it. Of course, other production capacity will not be released. Another example is the famous iFile, which does not open the recycle bin by default. If you open the Recycle Bin, you may forget which files you deleted.
Cleaning method:
Find the recycle bin folder of the file management software and delete the files in the recycle bin.
5. The software manually installed by 5.Cydia and App is included in other capacities. If you install all the software through these programs, there is no need to make a fuss that others will be so huge, and the garbage is there. Delete what you don't want
①/private/var/mobile/library/netdragon/applications is the path of residual junk files after the installation of 9 1 program failed. Only failed installers can be deleted. If the folder is deleted, the program cannot be opened.
②/private/var/cache/apt/archives/partial cydia will delete the downloaded content irregularly, and the download of Cydia can be resumed at the breakpoint. If you reinstall it, you may continue to download it. If you start from scratch, the parts that have not been downloaded will be automatically deleted. If you don't want deb files, you can delete them directly if you haven't downloaded them.
③/var/mobile/media/application archives When the second computer starts iTunes synchronization, if the computer does not have the software on the iPhone, it will prompt whether to transfer the software to the current computer. This temporary ZIP-format APP software was generated in this directory. If it is available, please feel free to delete it!
6. E-mail attachments are also in other rooms. If you have undeleted email attachments or downloaded email attachments, you can delete them to make room.
7. ipa and deb downloaded by 7.safari. If you installed the Safari download plug-in, do you remember to clear the downloaded files?
The virtual memory in the 8.var/vm directory was previously installed. If there is, delete it.
9, var/mobile/library/caches/directory, if there is a virtual file at the beginning of Proswitcher, delete it (never delete all files in this directory directly, otherwise all your programs will become other, and backup is useless! Never! )
10, the most common file copied by yourself is the font file. For example, there is a dictionary library that FY has copied 230M, which is located in the dictionary unique directory. Itunes shows 3.47G applications, while iFile is 3.7 1G directory for viewing applications, which is just a dictionary library. Delete it yourself.
Note: a, pay attention to backup files before operation, just in case.
B. After i-FunBox is directly deleted in steps ① and ②, the machine must be turned off and restarted (cancellation is invalid), otherwise pictures, music and videos cannot be played synchronously and normally. Because deleting directly in i-FunBox will not update the iTunes library. Some children's boots synchronization problems can be solved by restarting the machine. I emphasize here!
C "other" cannot be completely removed. The newly brushed machine "Other" will take up 200MB. After i-FunBox directly deletes the media folder, it will "temporarily" delete "Other", but this is an illusion. After restarting the machine and synchronizing again, "Other" will come back.
D "Other" will not affect the stability and use of your machine at all. They just take up some space. Hundreds of megabytes are normal. A few g's can check the above items. Those who like to toss can follow the methods listed above and try to simplify "others".
