I would like to know if it is possible to write in a text file without overwriting its current contents and without creating or merging Lists of string etc. So lets say i run the program once and i write Hello , and when i run it again i write Everyone so the txt has now Hello Everyone. Moreover, does anyone know how to read only a specific block of line from a file, for example from , to , or from Dear to Best Regards etc. Thanks a lot in advance!!! I hope that my question is clear enough

Select the Components tab and right-click on the component name. Select Details; the Component Details dialog appears. Mark the checkbox option to "Never overwrite if keypath exists." In addition, make sure that the file is the keypath of the Component in the File Key Path field. Click OK.
You're overwriting the content of the file every time because you're using mode w to write the file, which re-writes the file from the beginning. If you simply want to append your data to the end of the file, you should use mode a like this: fptr=fopen("program.
fwrite() does not exactly overwrite by using fseek(). Instead, there are several cases: if the open permissions was 'r' then writing is an error.

To append text to a file you can use the methods File.AppendText or File.AppendAllText.
