Cisco 2802 access point image upgrade

[CarrefourIT]

Hi, After i've downloaded cisco mobility express image ( Release 8.10.185.0) when i have opened the file to take image copy to add it in the tftp command with (Bin) extension i could not find it as shown in the attached images

I don't understand the question, these are almost all .bin files
only you need to modify the options in your explorer settings to disable   "hide extensions for known file types" 
explorer -> view - > options -> view -> hide.....

what i mean is what path should i type here in the xxxx
ap-type mobility-express tftp:1.1.1.1/xxxx

[pieterh]

the image names shown are the images that the AP2800 by default supports as ME client ap
you need the corresponding image for your access point

for an 2800 it will be:

• ap3g3 - 2800/3800/4800/1560/IW6300/ESW6300 series (AP-COS)

what does the TFTP server show?
If you're using windows did you disable the firewall or allow the TFTP server?

The file names are correct.  No file extensions.  Exactly as they need to be because that is what the AP will request when it needs to download.

The apname_decoder.inc file includes the mapping of image name to AP type:
/*AP Models and their Associated Image Names*/
AP1850(ap1g4)
AP1830(ap1g4)
AP4800(ap3g3)
AP3800(ap3g3)
AP2800(ap3g3)
AP1560(ap3g3)
IW6300(ap3g3)
ESW6300(ap3g3)
AP1815i(ap1g5)
AP1815w(ap1g5)
AP1815m(ap1g5)
AP1540(ap1g5)
AP1840(ap1g5)
