For some time I've been using the UD facility to store .pdf copies of the Jeppesen charts for my home field and primary diversion. This has worked fine on a Lenovo tablet with the relevant folders stored in the (Android > Data > aero.skydemon.skydemonandroid > Files). folder.
However I cannot get anything to appear in my Huawei back up tablet. Putting the files in the same place doesn't work. Putting them in as separate pages doesn't help.
I've uninstalled and reinstalled SD. I've cleaned the system cache and cleared all stored documents twice. The only thing I can note is that being a 16gb drive it's now down to its last few hundred megabytes of memory so might be straining to cope. Also, that the Lenovo installation includes a 'cache' folder that the Huawei doesn't have.
Not really an SD problem of course, but I wondered if anyone has solved anything similar on other products.
Thanks.
