Problems managing files

I have the same problem
I had 330 photos (500MB) in directory xxx
I selected these files, cut them and pasted in directory yyy
both directories are on the external SD card (FAT32)
moving files on the same partition should take less then second but it took few minutes
then alert appered saying that AirDroid can't move files on external SD card
but despite that files were moved
then I downloaded directory to my pc and found out that airdroid duplicated some of the files (416 files instead of 330)
sometimes files were empty (0 bytes) and sometimes fully duplicated

I use Airdroid for more then 2 years but I haven't use cut/paste feature on more then 5-10 files before

Phone: ASUS Zenfone 5 (A501CG)
ROM: Stock
Android: 4.4.2
Rooted: Yes
Using wifi and Firefox on Linux Ubuntu
SD card: 8GB (with almost no files)

Thanks for the feedback. You will look into this

I have now installed airdroid v2.1 and can confirm that the problem doesnt occur. I can cut and paste instantly without taking forever for the hard drive to physically copy and paste. It also removes the problem of duplicates being created
