Graeme,
Thanks for the info but my problem is with getting information from the SD card not writing to it. I have already got information on writing to the SD card on tablets with the newer android system. The problem I have is with a particular tablet make that seems to have made the storage path different than that of the standard system.

In an earlier post you said " MSP is set to send files to /storage/emulated/0/Android/data/com.zubersoft.mobilesheetspro/files."  To me it would seem that you are not writing the files to the external card, this command indicates they are going to the internal storage area - which would explain a lot of things, or at  least the fact that you can't load all of your charts for lack of internal space.*

* I just had a quick look at the specs for this tablet. It has 32 Gb of internal memory, so I am really surprised you seem to be running out of space. What sort of charts are you loading?

Could I ask you to at least try the procedure I outlined and see if it hellps at all. Until you can get your charts on the external card, you will never get it to work as you want.

If Mike is right and it proves impossible to access the external card in any way (which would seem a very strange thing) then I'd take it back to the place you bought it from and tell them it is unfit for purpose!  Ask them to change it for a model that does do what everyone would expect of a tablet.
