## Prompt when creating a new file in a network path check box

## Always Add to Recent Documents Folder check box

## Use uchardet to detect file encodings when the Detect All option is set check box

When the Detect All option is used to open files, EmEditor will use uchardet (C++ fork of Mozilla Charset Detectors) to detect file encoding.

## Open US-ASCII as System Default Encoding check box

If the detected file encoding was US-ASCII, EmEditor will open the file as the system default encoding.

## Always Show Detect All Result check box

Always displays the Detect All Result dialog box when the Detect All check box is selected when opening a file, or when the Reload Detect All command is selected. However, if UTF-16 with signature, UTF-16 without signature or UTF-8 with signature is detected, the file will be loaded immediately without displaying the dialog box.

## Show only when Multiple Encodings Detected check box

Displays the Detect All Result dialog box only if multiple encodings are detected when the Detect All check box is selected when opening a file, or when the Reload Detect All command is selected.

## Show Detect All Result also during Find in Files check box

## Avoid Printer Access check box

Avoids access to a printer. If this is checked, when EmEditor is launched, even if the Show Page Numbers check box is checked, page numbers will not be displayed until the Print command or the Print Preview command is selected. This option is recommended if the printer access is slow.

## Displays Large File Controller when a large file is opened check box

If this is checked, EmEditor automatically displays the Large File Controller when it opens a large file (larger than the size specified in Minimum File Size to Open Asynchronously text box in the Advanced page of the Customize dialog box).

If this is checked, EmEditor will display a prompt dialog box if EmEditor loads only a portion of a file specified in the From (default) and To (default) text boxes.

## Prompt when default Open Filter exists check box

If this is checked, EmEditor will display a prompt dialog box if the Open Filter exists. The Open Filter can be set in the Large File Controller.

If this is checked, EmEditor will display a prompt dialog box if a Unicode (UTF-16) file size is an odd number in bytes.

## Enable file mapping when saving a large file check box

If this is checked, EmEditor will enable file mapping when saving a very large file if possible.

## Monitor files only while EmEditor is active check box

If this is checked, EmEditor will monitor files only while EmEditor is active.

## Verify files immediately after opening check box

When this option is selected, the newly opened file is saved as a temporary file, and its size and SHA256 hash value are compared to the original.

## Display verification results only if there is a failure check box

If you select this option along with the Verify files immediately after opening check box, the verification results will only be shown if there's a failure.
