I use the app for work and have a lot of custom pdf's forms that I use and wish to keep. There is plenty of space left on the ipad (8gb+) yet I am constantly getting this pop up to the point I am having to delete documents which I dont really want to do. Is there a maximum storage capacity ? If there is which it mush have for me to be getting these, would it make any difference if I was to save some in the cloud ? Or is there an easy way of moving all items to One Drive or Dropbox ?? Any help would be most appreciated.
Would you check the storage on your iPad?
You can transfer your PDF documents to a desktop/laptop computer and delete some PDF documents from your iPad to free up storage.
It's always good to make backup copies of your PDF documents so that you will not lose them accidentally.
Alternatively, you can store your PDF documents in Adobe Document Cloud (free cloud storage) instead of storing them locally on your iPad.
