Please suppose I have a text file with size 2 gigabytes.
In this text file I can see many duplicated rows.
I need to remove rows NOT containing the number 2713, and then to remove duplicated rows.
The duplicates can be removed with UltraEdit, but how can I remove, using UltraEdit, the rows NOT containing the number 2713?
And how can I proceed, if I want to remove max 10000 rows at a time, NOT containing the number 2713?
Thank you in advance for your kind cooperation.
