Delete lines in files (text files)

[Björnke von Gierke]

You should be able to read the file one chunk at a time. For example:

on mouseUp
   answer file "the huge file"
   if it <> "" and the result = "" then
     put it into theFilePath
   end if
   open file theFilePath for read
   repeat until the result = "eof"
     read from file theFilePath until return
     put it into theCurrentLine
     --do stuff here with theCurrentLine
     --but don't keep the data completely in memory!!!
   end repeat
   close file theFilePath
end mouseUp


Adjust as needed
