Sync files with phone via MTP(?)

[AZJIO]

I had an old direct USB phone and used my file sync software. There was no need to copy all the files, but only the changed ones, it was fast. When buying a new phone, which had advantages in Internet speed and page display, I had to give up synchronization and other minor little things. Now I again have a desire to understand, since the explorer sees the size and date of the file, but the request for this data is much slower. This is not critical, since overwriting all files will take more time than reading this data. But the problem is how do I make a request for files if the device does not have a drive letter. Do I need to use WinAPI and \\.\PhysicalDrive1?

I tried FreeFileSync, it performed synchronization without any problems in the form in which I needed, that is, comparison only by file size, type "mirror", that is, it repeats what is on the computer and outputs logs quite well about what has been done.

RSBasic created an MTP module long ago, maybe this helps: http://forums.purebasic.com/german/view ... hp?t=31465

Thanks at you two for the subject and the link
That works fine here with my old phone NOTE2
I don't know this MDP protocol and it's possible to communicate with Phone without ADB

But, i have not understand something, the DLL are compiled with the Github source code "Bassman2/MediaDevices" or i can found the last version already compiled elsewhere ?

there the sources are written in C, but compiled as a dll so that there is access in any programming language. thanks for the finished module, I wanted to answer later so that I could have a recursive example of searching for files and make my own help file. I had to save the code in utf8, then it worked, because there was a problem of the Russian language in the name of the root folder.

Thanks for your explanation

Your recursive research works perfect here
Thanks a lot AZJIO for your sharing and this very nice and useful subject

Phone-MTP
While testing the examples, I ran into 3 problems:
1. File date always returns 0
2. GetMTPFriendlyName() returns an empty string.
3. The author added 3 functions (CreateMTPDirectory, DeleteMTPDirectory, DeleteMTPFile), which are not in the example.
4. Some GetMTPDeviceID-GetMTPPnPDeviceID, MTPEntryName-GetMTPDescription-GetMTPModel functions return the same values. But perhaps it depends on the device, on what values ​​the manufacturer has entered there.
