Select Open Folder from the Project menu to open all files or files of a certain type from a particular folder.
You can type in the path to the folder containing the files you want to open into the drop-down list at the top. If you have recently opened files from this folder, you can select it from the drop-down list. EditPad Pro remembers the last 16 folders. Another way to select the folder is to browse for it using the folder tree. The drop-down list and folder tree are automatically kept in sync.
Mark the option "recurse through subfolders" if you also want to open files contained in subfolders of the folder you selected.
If you want to open all files in the folder (and optionally its subfolders), select the "all files" option. If you want to open only files from a certain type, you can select "files of type" and pick one of the file types from the drop-down list. The list will contain all the file types you defined in Configure File Types. This will open all files that match the file type's file mask.
To open files matching another list of extensions, select "file mask" and type in the list of extensions or file masks, separated by semicolons, into the "file mask" drop-down list. You can also select a recently used file mask from the drop-down list.
If you choose the "regular expression" option, then the regular expression must find a (partial) match in the name of a file for it to be included in the search. This regex is used to filter files by their names only. If you want to search through the contents of the files, use the Find on Disk command in the Search menu instead of the Open Folder command.
Tick "create new project" to open the files into a new, untitled project. This is the same as using Project|New Project before using Project|Open Folder.
Tick "open the files" to make EditPad Pro actually open all of the files. If you turn this off, then "add files to the project" is automatically turned on, and EditPad Pro adds the files to the project without opening them. The files will show up in the Files Panel as closed files. Since only managed projects can contain closed files, turning off "open the files" automatically changes the current or the new project that the files are added into a managed project.
Tick "add the files to the project" to add the files to the project. If you turn this off, then "open the files" is automatically turned on, and the files will be opened as outside files, without adding them to the project. Since only managed projects can have files open that aren't part of the project, turning off "add the files to the project" automatically changes the current or the new project that the files are opened into a managed project.
The Open Folder item has a submenu that lists recently opened folders. Each time you use Project|Open Folder, the opened folder is added to top of this submenu. Though the menu shows only the folder's path, all the settings from the Open Folder window are remembered by the menu. Select Maintain List in the submenu to see the settings used for each folder. When you select one of the remembered folders, EditPad Pro opens the files contained by that folder, using the same file mask and other options as you last used for that folder. If you have opened files from this folder more than once, the folder will appear only once in the Reopen Folder menu, with the most recently used settings.
"Remove Obsolete Folders" removes all folders that no longer exist from the Open Folders submenu. EditPad Pro does not check whether the folders still contain any files matching the file mask. EditPad Pro only checks whether the folders themselves still exist. "Remove All Folders" clears the Open Folders submenu.
