Disappearing files

Using my Nexus 7 I can connect and upload files no problem.

When I use the quick upload function this also works and I can see and play the files on my device. After I close airdroid and shut down the source PC the files no longer appear to be on my device...


I thought I had maybe accidentally deleted the upload folder on my Nexus but this has happened twice now. Standard file upload to a designated folder appears to leave the files permanently. Any clues?

same problem here. after uploading files they suddenly disappear. i have to upload them again. very annoying. :/
