Improved Speed by Multi-threading

EmEditor v15.1 has greatly improved the execution speed of Find, Replace All, Filter, Undo Replace All, and Select All Occurrences commands. When dealing with large files (more than 10,000 lines), these commands run as multi-threads. EmEditor can also be customized to show the execution time for many tasks.

Extract Columns

This version added the Extract Columns command, which allows you to extract specified columns in the CSV document and create a new document.

Per-User Install

The new version allows you to perform a per-user install. A per-user install will not display User Account Control (UAC) prompts on Windows 7 or later. The per-user install is possible by selecting the Only for me radio button on the Installation Type dialog during the install. If a quiet install is made inside the Command Prompt, add the “MSIINSTALLPERUSER=1” option. The Installation Type cannot be changed during updates. All the shortcut settings can be changed now even in the per-user install.
