I have noticed that the internal storage of my tablet is filling up even though I have tried to link as many of the apps as possible to the SD card using Link2sd. I did a quick search for duplicates using Search Duplicate File(Super). What I found was that 1117 files where duplicated in both the /mnt/internal_sd/ and /mnt/external_sd directories. Any idea why this has happened, and how I can free up this space?

I have searched both paths and none of them are symbolic links to the other. These are actual duplicates of the files.

I also did a listing using adb shell of both the /mnt/internal_sd/... and /mnt/external_sd/... paths and they both show up as no symlink. So as I understand the data must be duplicated. Unless someone can prove me wrong. A screenshot of Link2sd properties of the app is below this.

Link2sd iplayer link properties. 720MB is supposed to be linked to external_sd but shows up as duplicated in the listing above:

This app may make new apk files like backup from apps or something like this , you can use another link to sd apps that arnot make new apk files.

    What's the point of having an app that duplicates data that is supposed to save space? Find it hard to believe. – Jacques MALAPRADE Jan 30 '16 at 22:55

LINK2SD makes symbolic links, one file would just be a pointer to the real one. If you go to a terminal prompt and cd to that directory and do a "ls -alF" command, you will see one of these files is a zero size link, the other the actual file. This is how LINK2SD works.

  • I amended the question to include a listing as you said. I see no zero size link anywhere on the path. I used and example path for which I know there is supposed to be data on the internal and external sd partitions. – Jacques MALAPRADE Jan 31 '16 at 11:17
