Folder navigation & file selection

The structure of the files is similar to that of a normal file system. There is a tree of folders where the files are located. Clicking on a folder opens its contents.

To select files and folders, just click on the checkbox to the left of the file or folder. If you want to select more than one file or folder at a time, you can click the first checkbox, then hold down the SHIFT key and click the last one. All files and folders from the first to the last will be selected. To save time, you don't have to click on a checkbox. Just put the cursor on the row with a file or folder and press SPACE, and the file or folder will be selected as if you clicked on a checkbox.

There are also buttons to quickly select/deselect all files in the directory, as well as to invert the selection. Above there is a choice of file sorting type.

You can also select files and folders by text search in the name (filter). For example, you can select all files or folders with ".jpg" (pictures) in their names. You can add frequently used filters to the panel for quick use as buttons. Then you don't need to enter the text for the filter every time, but just click the button with the desired text.

To prevent accidental selection of files (to avoid possible unintentional deletion), you can lock a folder so that it cannot be selected. To do this, just click on the folder image so that it becomes green. In this case the folder itself cannot be selected, but if you open its contents, you can select files and folders inside it.

If you click again, the folder becomes yellow, with a lock on it. This means that not only the folder itself but also any file or folder inside it cannot be selected.

If you click one more time, the folder returns to normal mode, becomes yellow, and you can select it and all its contents.
