1. Clean directly with the "garbage cleaning" function of iTools. Connect the device, and enter the advanced function "Clean up the garbage" of iTools. ITools will automatically clean up the excess garbage in the system and wait patiently for completion.

If you are still worried that the cleaning is not clean, you may wish to thoroughly check the system and manually find the cleaning.

2. Directory/user/media/application archive/software compressed packages that can be safely deleted and have deletion errors.

3./user/user/media/publicstage can find redundant application files that failed to install.

If you want more memory, there is another way. Open LibraryCaches in the document management application of iTools, and delete the records in the Caches folder (named Cache.db).

The files in PS: documents are user files. Deleting is not recommended. But deleting some pictures and access records can also clean up the memory.

5. If your ipad mini escaped from prison, you have also used other tools such as 9 1cydia, 9 1 assistant, all of which are manually installed in the/private/var/stash/applications folder. The folder name here is clear at a glance. Find the software junk you want and delete it directly. The premise is that you deleted it once on the iPad mini, 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.

6. Enter the iTools file system, jailbreak the system -/tmp, and delete the newly discovered files that failed to synchronize or delete iTunes, as well as the folders named after the type of install_greenmile.XXXXXX.
