Hi thanks guys but this lines do not work on primo. I test multi Igo instalation on my device.
on igo8 i have this in sys txt. Content on memorystick - everything work! it reads automaticaly the content from memorystick.

[folders]
app="\Mounted Volume\IGO8"
data="\Mounted Volume\IGO8" ;custom,save
content="\Mounted Volume\IGO8\content"
sdcardpath="\MemoryStick"
on Igo amigo this in sys txt. its similar to igo8 Content on memorystick - everything work! it reads automaticaly the content from memorystick.

[folders]
app="\Mounted Volume\Amigo"
data="\Mounted Volume\Amigo" ;custom,save
content="\Mounted Volume\Amigo\content"
sdcardpath="\MemoryStick"
But on primo this is Not working! even when i put it so:
[folders]
app="\Mounted Volume\PRIMO"
data="\Mounted Volume\PRIMO" ;custom,save
content="\Mounted Volume\PRIMO\content"
sdcardpath="\MemoryStick"
map="\MemoryStick\IGO8\content\map"
I tried everything what i have found on net but nothing work.When i type the content folder for primo on memory stick and put this line in sys that it muss read lang an voices from internal memory it is not working.
lang="\Mounted Volume\PRIMO\content\lang
voice="\Mounted Volume\PRIMO\content\voice
Currently i have this but this is NOT a option for me:
[folders]
has_secondary_root=0
sdcardpath="\MemoryStick"
app="\Mounted Volume\PRIMO"
data="\Mounted Volume\PRIMO" ;custom,save
content="\MemoryStick\IGO8\content"
i have found on net this line in sys.txt
[folders]
secondary_root="IPAQ\NAV"
what make this line? i have not tested it yet (no time).I thin when i change the="IPAQ\NAV" with "IGO8" will it look on this folder?

thanks for answer
