File.Move to SD card

[Guest]

Ahg..
A feature in my application allows the user to move files (program resources) from one folder to another (with the idea of allowing the user to store the resources in a SD card if so desired
This code works with out a problem when transferring files from one folder in the device to any other folder on the device. However, the same code fails when transferring files to a folder in the SD card
All I get is an IOException and no other revealing information (even using System.SR
It only happens with a few files towards the end of the process and not necessarily the same files
Note that I am transferring a large number of files 192 for example.
It feel like something is going on that does not like the fact that I am transferring so many files, some sort of caching

I use File.Move( ... ) to transfer the files

Is there something I can close or reset to prevent this from happening

Note, no I am not going over the size limit of the SD card. The SD card holds 64MB and all the files add up to 7 MB

Thanks

My understanding is that SD, CF, etc. uses FAT for their file system. FAT
does have a limitation on the number of files that can be stored in the
root directory. Could this be the issue you are encountering?

Thank you so very much. That is precisely the problem we where having! We added a folder to the root directory and everything works fine now
Outstanding catch. Thank you very much
