Wondering if someone can help!
Trying to back up my iPhone 5c through iTunes on my desktop computer but i get an error message about "not having enough free space on my computer - try removing files and deleting recycle bin".
I have done this but it hasn't made a difference (recycle bin is empty and iPhone has 11gb free space, computer has 280gb free space). I tried resetting iPhone, turning computer on/off & the same message still occurs.
Both my husbands iPhone & our iPad will back up no problems running same software.
I've tried backing up through iCloud but I get the same storage error message....makes me think it's a setting on my phone?

iPhone software is 9.3.4 and iTunes is 12.3.2 - i am aware of the new ios 10 which i don't want to download as we have very limited download limits.
Have tried apple support website but for this error I must phone them & pay support, trying to avoid that if I can.
Any suggestions?
