Hello A-D-T,

I am sorry but when EmEditor opens a large file using a temporary file (larger than specified size in the Advanced tab of Customize dialog box), it becomes slow when it needs to add or remove lines. If possible, you can increase this size so that it can be a little larger than the size of the file you are trying to open.

Please let me know if you have further questions.
Thank you,
