Complicated find and replace txtpad how to???

[actroid]

Hi i try to manage 5400 txt with md5 encypted file like this

file1: data.txt
user11:Il7RClgIkRuM
user111:ILvZ1NpSYlIs
user2:I53bn0K9a4Dk
user22:IJX8JuIXcZ0Y
user3:IxdocDri8HB.
user33:Is34.EMN0yrY
etc

file2:data1.txt
ILvZ1NpSYlIs:found1 ( this example from user11)
Is34.EMN0yrY:found2 ( this example from user33)
*** this file contain only successfull md5 encypted

how to make txtpad replace "Il7RClgIkRuM" in data.txt with "ILvZ1NpSYlIs:found1" from data1.txt

result from data.txt will be like this:
user11:Il7RClgIkRuM
user111:ILvZ1NpSYlIs:found1
user2:I53bn0K9a4Dk
user22:IJX8JuIXcZ0Y
user3:IxdocDri8HB.
user33:Is34.EMN0yrY:found2

I dont have any idea how to bulk replace from data1.txt to data.txt,
i do it one by one before . is it possible used txtpad to filter this?

TQ very much..
