Using windows 10 to sync (mirror) with a galaxy note 4 running Android 5.0.1 .MTP mode using file content compare.

When I have an unchanged .txt file and trying to sync I get the following message when it's "updating attributes".

Cannot write modification time of "mtp:\SAMSUNG-SM-N910V\Card\Asopkin\my data\12 word data\readme.txt".
IPortableDeviceProperties::SetValues failed for WPD_OBJECT_DATE_MODIFIED.
HRESULT: 0x80070032, The request is not supported.

Seems to transfer .txt files correctly only gives error on unmodified file during syncronization step.

A lot of MTP devices simply do not support setting the modification time, thous the error. When copying a new file to such an MTP device the operation seems to have succeeded, but in fact the modification time was also not set. (=>This is a silent failure and can be considered a bug of the MTP device). Practically speaking it is best to ignore these errors since there is nothing that can be done about them.
