I am sorry if this question has been asked before.

Can Java program read a map file from SD Card? If yes, can it be several files?

thanks guys

If the device supports File Connection API (part of JSR 75) and the map files are stored in a directory the midlet has access to - yes (however as I do not exactly know what "map" files you mean, you have to be able to parse them too). If you are trying to read huge files, on some devices the midlet might run out of memory.

Please check the FileConnection example and document at

And to pick a little nit: No Nokia phone model supports SD cards. There's those that take miniSD and microSD, and there's MMC, RS-MMC, DV RS-MMC, too, but no actual full-size SD card.

In this case, the technically correct answer would be: No. No software - Java or otherwise - can read files from SD Cards on any Nokia device. ;)

There's also no CF card, SmartMedia or MemoryStick card support in Nokia devices today. :)

A more "generic" term would be to refer to these as just memory cards.

Once that's settled, Hartti's reply is the correct one; JSR-75 is the answer, if the phone model in question supports JSR-75 (depending on the device, restrictions may also apply on which directories/folders are visible to the program and which aren't).

Full-size SD cards are largely compatible with MMC, are they not? I think the 6230i, at least, should be able to read them. ;)

No. Full-size SD cards are thicker and have additional pins/connectors than MMC cards.

An SD card reader/device is compatible with MMC, but vice versa is not true (i.e., a device made for MMC cannot take/read/use SD cards; it won't even fit, if properly manufactured).

Uuups, my bad, I did not read the question carefully enough. Missed the "SD" part as non-relevant. Thanks Petri for your hawk eyes!
