file updating in mtp device, freeze & crash

[alaskaita]

Synch of the new files between folder in c:\ and another folder in a device with mtp access, works very fine.
Synch freeze instead if the file is not new but it has to be updated in mtp device.
FFS ver. 8.4 or 8.7 or 8.8;
PC c:\: win7 64 bit
mtp device: Samsung Galaxy S7

Does it make a difference if you turn off Menu->Tools->Options: Fail-safe file copy?

[alaskaita]

no way. no synchronization of files that already exist, but to be updated in the folder on device mtp

What if you delete the target file manually via FFS's main dialog?

[alaskaita]

Manually deleting the first file on the mtp device side via FFS's main dialog is successful but manually deleting the second file, FFS hang up and freeze.
