Have you ever tried to lose weight? We have successfully lost weight in L7, and hope more friends can share their better methods.

First of all, let's be clear about the principle of determining that files can be deleted:

1, according to the attributes of the file. If the file attribute is archive (X0020) or has no attribute (X0000), then we can safely delete it. Because this kind of files will be automatically deleted after the "comprehensive cleaning" operation of the mobile phone, and will be automatically generated after normal use.

2. Delete unnecessary function files. We seldom use some functions in L7, or it is impossible to use them under the present conditions, so we should delete some files related to this function, but keep the files with the minimum size to maintain the normal work of this function.

3. Delete personalized ringtones, wallpapers and standby images. According to personal preference, delete such large memory users appropriately.

note:

Be sure to back up the file before deleting it. Because it is impossible for us to have a comprehensive and in-depth understanding of all L7 files, unexpected problems may occur after slimming, so it is very important to restore the original files. At present, the commonly used backup software, such as Flashbackup, seems to be unable to apply to L7. So you can copy the original file deleted by L7 to the local computer through P2KCommander, and record its attributes for recovery.

Specific files that can be deleted:

A\*。 Gif (note: *. Gif refers to all files with the extension of gif, the same below. )

A\*。 Css (the above two categories can be carefully deleted, and some functions are unknown, but at least I found no problems after deleting them)

A\*。 temporary file

A\*。 database file

And all files with the attribute of X0000 (x is defined according to the file source, such as 7 means copying through USB cable).

(This file will be automatically generated after deletion. )

a\mobile\audio\MyToneDB.db

A\mobile\audio\TempToneDB.db (The above two database files are set to save the ringtone list in the ringtone list and the user's ringtone. After cleaning the ringtone file in the folder c\mobile\audio, there will be an error in the ringtone list, and the deleted ringtone still exists. Therefore, it is necessary to delete the last two files or do a "general cleaning" operation after all cleaning is completed, in order to automatically generate the correct ringtone list. )

The files under a\mobile\certs are security certificate files of programs such as java, and it is not recommended to delete them.

It is recommended not to manually clean the files in the folder a\mobile\kjava, which records the authorization files of java programs (program files are under c\mobile\kjava), and the corresponding java programs can be uninstalled in the mobile phone.

You can delete all files in the folder a\mobile\mib\pcf.

*。 Txt files under a\mobile\mms are strongly recommended not to be deleted, and cannot be edited after mms is deleted.

A \ mobile phone \ setting saves the setting file in the mobile phone, and it will be automatically generated after deletion. It is recommended to delete.

In a mobile system, shutter 1(~5). Amr is shutter sound. Some slimming tutorials suggest deleting it, but after I try to delete it, the deleted sound will not be automatically cleared from the shutter sound list, so deleting it is not recommended. Count_down_5.amr and count_down_ 10.amr are the countdown tones for taking pictures (corresponding to 5 seconds and 10 seconds respectively), so you can consider deleting one of them. Wvim _ Yan Wen _ Yahoo and wvim _ Yan Wen recorded the characters corresponding to Yan Wen in instant messaging software, which can be opened and viewed in Notepad. If the characters in c\mobile\picture are considered for deletion, then both files can be deleted here. Other files not mentioned are not recommended to be deleted.

a \ mobile \ wvim \ wvim _ alert _ im _ AOL . mid

a \ mobile \ wvim \ wvim _ alert _ im _ ICQ . wav

A \ mobile \ wvim \ wvim _ alert _ im _ yahoo.wav can be completely deleted (the above three files correspond to the alarm sounds of three instant messaging software respectively. L7 can't recognize WAV format sound files at all).

It is recommended to save it only in the root directory of drive C.

phone book _ create _ new _ 30x 30 _ c . gif

phone book _ mailing _ list _ 30x 30 _ c . gif

phonebook_no_image_30x30_c.gif

phone book _ sim _ entry _ 30x 30 _ c . gif

Phonebook_loading_30x30_c.gif (the above picture will appear in the address book).

j2me 15x 15icon.png

J2ME15x15icon _ vscl.png (the picture above shows the default icon for java programs).

It is recommended to save it under c\mobile\audio.

AlertFile00 1.mid

AlertFile064.mid (the above two mid files correspond to prompt tone and standard tone respectively).

Besides Start~up.mp3, it is best to keep at least three original *.mp3 files, because if there are less than three, the hidden file Start~up.mp3 will appear in the ringtone list.

The folder c\mobile\kjava contains java program files, which can be deleted by uninstalling the corresponding programs in the mobile phone.

C\mobile\btprint is related to Bluetooth printing, and there is no problem after deletion.

C\mobile\mms\mmstemplate is a multimedia information template, and it is strongly recommended to keep one, otherwise the multimedia information template will not be used.

It is recommended to save it under c\mobile\picture.

Speed.jpg

Teamwiner.gif (the above two files are the default wallpaper and screen saver pictures of mobile phones)

C \ mobile \ picture \ WP _ moto _176x220 _ c.jpg (Moto theme contains the wallpaper of the lower panel file in location c\mobile\skin\MOTO, so it is recommended to keep it).

Other *. Gif can be deleted as much as possible. The jpg file at the beginning of wp is the wallpaper of the corresponding panel, and the picture should be emptied after deleting the panel.

The folder c\mobile\skin is a mobile phone panel file. When deleting, be sure to select the panel folder to delete, and then delete it. Do not enter a specific panel directory and delete individual files (*. Skin and *. Dat) one by one. Because a folder with empty contents will not be displayed in P2KCommander, when there are no panel files in the panel folder, the folder is invisible and cannot be deleted directly, so the deleted panel items will remain in the mobile phone.

In addition, it is strongly recommended to keep the MOTO panel.

It is recommended to delete all video files in the c\mobile\video folder. If you think it is valuable, you can copy it to TF card.

Finally, perform main reset and main clear. At this point, the main cleaning work has been basically completed.
