Thanks for the screenshot of the WPD Info tool. From all the data gathered so far this looks like bug or data corruption of the MTP device: - Both WPD_OBJECT_SIZE and WPD_RESOURCE_ATTRIBUTE_TOTAL_SIZE of WPD_RESOURCE_DEFAULT report an expected file size of 843831 - However FFS reads 844085 bytes un...

Using FFS 7.6, under Win 10 Pro x64, whenever I attempt to run a sync from an MTP source, to any desitination, I get the following error (screenshot attached): > Cannot read file "mtp:\XXXXXXXXXX\Internal storage\Pictures\XXXXXXXX\XXXXXXXXXXX.jpg". > > Unexpected size of data stream. > Exp...
