At /Nintendo 3DS/<SomeID>/<SomeID>/extdata/<ExtdataIDHigh> on SD is directories for each title.(ExtdataIDHigh seems to be always 00000000) Some titles have Quota.dat stored in these directories, not all titles use it. The dirname for these directories is the ExtdataIDLow. Then there's a sub-directory 00000000, which contains the actual extdata. Size and number of files in this dir varies per title.

Regular apps can only mount SD/NAND extdata using the same extdataID which is stored in the [[CXI]] exheader. Therefore, regular apps which have the exheader extdataID set to zero can't use extdata. System apps can mount arbitrary extdata.

This restriction doesn't apply for NAND extdataIDs with bitmask 0x48000 set. System apps can mount arbitrary extdata.
