    Default Sygic map update differences, apk vs downloader

    Why are the TA folders I download directly from Sygic server larger than the ones I download with Sygic Map Downloaders - Coded by MrDude.
    example .. bel.ta 2019.09 209 MB (219,625,392 bytes) 12 files .. Coded by MrDude download
    bel.ta 2019.09 213 MB (223,444,583 bytes) 15 files from Sygic server update

    I noticed earlier that when it is downloaded from the application, checksum files are present (.crc). You are free to delete all of them.
    I haven't downloaded this way soon, maybe there are some more differences

    Edit:
    just tested for my country. One extra file is downloaded via win software > nhs
    It is possible that there are more differences for other countries.

    This has been discussed much earlier, I can't remember what the role of this file is

    What are the three extra files that it downloaded (apart from crc which is just a checksum to make sure the map downloaded properly).

    Here is a screen shot

    As pointed out by Boki_Srb the nhs file is extra with the DL

    I repeat
    This is a known situation, since a very long time...Some other tools were used then.
    Why ... well, we just don't have an answer to that question.
    That is, the real question is why the apk does not download that file.

    It's not a big deal - I suppose you could just delete it (nhs file), if it's an issue. The thing is that it's not doing any harm. CRC files are unimportant, these are just a checksum to make sure that some files were downloaded properly - they are maybe useful if you are resuming a map download from within the app. We could always just generate these ourselves if we wanted, but they don't serve much purpose so it's kind of pointless to worry about these to be honest.

    You don't have to explain to me, colleague

    I always delete crc files. And it’s just a matter of curiosity as to why the software doesn’t download nhs file.
    As I mentioned, I don't know its role.

    Otherwise, i use 2dc files (buildings) from osm maps. Richer contents.

    OSM + TA?

    A very interesting mix :-)

    Did you check if this arrangement produces 'Richer contents' with NT maps as well?

    And very efficient :d
    I haven't used NT maps, but it's not a problem for me to try, I'll try a little later and publish the result.

    But, if it has anything to do with it, with older classic downloaders, OSM maps are downloaded and placed in the same folder as TA maps.

    Edit:

    Much better situation, at least in my neighborhood...

    @Boki_Srb

    Thanks for the idea and the test you did.

    Although it's better than nothing but, the result is a bit problematic with my area because, its OSM maps are updated to 2018.12 and NT maps to 2020.06.

    P-S: With NT 2dc, in my region, there are no buildings at all!
