For example, if you set this to 51,200 KB (which is a good threshold for most), UltraEdit will not use temporary files when you open a file that is more than 51,200 KB (50 MB). The threshold will set a limit for using temporary files on files that are over the specified amount. We recommend that you set a threshold for the temp file setting for files above a certain size (specified in KB). Important note: This does mean you are directly editing the original file so any changes will be permanent. Enable the option to ' Open file without a temp file.' This setting may be accessed in Advanced » Settings » File handling » Temporary files. By disabling temp file creation on load, UltraEdit will not first copy the file to your temp directory. Copying the file can cause the initial loading to be very slow, especially with huge multi-gigabyte files.

However, when opening the file with a temporary file, UltraEdit must first create a copy of the file in your temporary directory. As UltraEdit uses 64-Bit handling for the file it has no real limit on file size, and does not use excessive RAM for editing. This is probably the most important tweak you can make to improve performance when opening very large files.Īs mentioned above, UltraEdit is a disk based editor, which means it only loads small portions of the file into memory.
