FTP information is kept in the "uedit32.ini" file under "[FTP Account -]"
Each account begins with "[FTP Account - Dennise]" in this case Dennise is a server I FTP to.
Oh the "uedit32.ini" can be two places depending on how long you been using UE.
1) C:/Program Files/UltraEdit/ Old way before version 10.20
2) C:/Documents and Settings/signon_name/Application Data/IDMcomp/UltraEdit/ New way since version 10.20
Before reinstalling windows I had UE32 installed from version 10.00 to the current 12.something so I backed up the .ini file with all the FTP sites definitions.
After reinstalling win and UE32 12.10, I could not be able to retrieve my FTP sites in any way; I tried to copy/paste the section in the new .ini file but with no success...
Maybe this should be a feature request for a new version??? it could be very helpful to have a tool or something for migrating the FTP accounts.
