You'll have to reveal a lot of detail. I get the feeling you don't like Windows, Android and how techy it all gets. I agree, it shouldn't be like that. This is where the customer votes count. (the returns counter.)
If you want to dive deeper, tell a lot more.
I have tried all night to copy files from my USB memory stick onto an internal sd card, and with no success
Have tried to look on the web but every thing I find is different from my apps
I have tried MY Files
and up load the appAstro File Manager
both find the files on the uSB memory stick but will not copy to the sd card in the tablet
Can someone help a damsel in distress or recommend a better app
