General options

The following options are available after choosing tools/options/general menu command (the obvious ones are not presented here):

General

Activate Drag&Drop Safety Guard. It accidental dropping files or directories happened to you, then activating this options may be useful - if the Drag&Drop operation lasted suspiciously shortly - ACB will ask you if this was not an accident and if you want to continue.
Deactivate Drag&Drop at all. It appears that sometimes certain Users don't want Drag&Drop at all, so it can be turned off.
Always open with workspace. First create one, then select it here if you want.
Don't generate statistics. ACB tries to remember mostly visited folders, which is then usable when you start typing in the address bar. If, for some reason, you don't want that, you may select this option, ACB will not gather statistics and will delete existing statistics' file. This will deactivate suggestion tool and Other Locations (part of Quick Access Bar).

Make objects bold if newest ones or exists in favorites. Did you notice that certain files and directories are made bold in the list? If you don't like that, turn it off.
Run conversion when image dropped. Well, first of all - if you will drag&drop an image to ACB (or copy an image and paste to the ACB), then ACB will create an image file, representing this image. However, it will ask you about the conversion details, turn it off if you do not want this. If you do it, then the image will be saved as bmp (windows bitmap).
Font. Here you can specify default font used in the files' list. To specify a color dependable on the files' extension, use Tools/Queries Management menu command.
Menus and selecting/right mouse button. Here you can define an action after pressing right mouse button, if you prefer an "old" way - use it to select files. Then to show context menu, use right-left click, or shift+click.
Menus and selecting/primary menu. Specify menu which should appear as the primary, the alternative you can get by using right-left click, or shift+click.
One icon click. If you want ACB to distinguish between clicking the file\folder name and the icon. If this option is set, then clicking the icon is equal to double click.
