Uploading Map Files ???

[marsorder]

Hello

Could some on advise me on what the protocol is for uploading map files is?

1. Which files from which SPMMBT folders are required

2. What file number should I use. For example map number 150? Will that overright some ones current 150?

3. Should I Zip the file?

4. Can I attach a word document to the upload?

Any help would be most appreciated.

Thank you
