Re: Regular Expression Searching Too Slow In Some Large Text Files I've just experienced this problem doing a Replace All.
I have a csv file (not yet saved) with 164000 rows in it. I did a Replace All changing \n with ,\n (added a column to the end of the data row). A popup appeared with a check box 'Accelerate by Discarding Undo Information' which I ticked. The action took minutes to complete !!! Previous versions used to run significantly quicker. The 'Additional Lines to Search for Regular Expressions' is set to 0. I ran the Replace All again with the same criteria and it took just as long. I ran a third Replace All changing ,, to , and the process took less than a second. The problem would seem to be related to regular expressions. Is there any way of disabling the undo during a Replace permanently ? |
