| Manual mode properties |
- User can use the [Print screen] key to capture the full desktop screen.
- User can use the [Alt]+[Print screen] keys to capture the active window only.
- User can activate the process by clicking the "Begin" button: TGrab will now check the system for a newly caught image every second.
- User can activate the process by clicking the "Hide" button: TGrab will now also check the system for a newly caught image every second, but will operate while fully hidden from the desktop. (TGrab can now only be closed from Windows Program Manager - no novices, please - or by a reboot).

| Supported image formats |
- Bitmap ".bmp" format - Windows Device Independent Bitmap.
Recommended image format for business use - maximum image quality, but a larger image filesize. Recommended format, if max. quality is required.
- JPEG ".jpg / .jpeg" format - Joint Photographic Experts Group.
Very good image format, optimized for photography, with an adjustable "image quality / file size" ratio (see the "Preferences" dialog). This is actually TGrab's default format, with a preferred "compression / image quality" ratio of "80" (where a ratio of "100" is the max. image quality, resulting in min. compression). Recommended format for overall images. Filesize is very efficient, when compared with the other supported formats.
- Windows ".wmf" format - Windows Metafile.
A Metafile is a collection of structures that store a picture in a device-independent format and was designed for the Windows V3.x operating system. The Metafile format is useful to transfer images between applications that do not have other options available, but is not the best choice for image storage.
- Windows ".emf" format - Windows Enhanced Metafile.
An Enhanced Metafile is used in applications meant for the Windows95 (and later) operating systems and is an improved version of the ".wmf" Metafile (see above).

| General settings properties |
- Holds image storage path, filetype and basis filename. Use the "Select" button to select a preferred folder. In the now available selection dialog, you can also enter the preferred filename and filetype.
(Note: By default, this filename will be expanded with a sequentially incrementing number, during the session. The procedure overwrites existing filenames without warning, to avoid unwanted interruptions in the capturing process. You will want to provide a new basis filename per session. The option to insert the number can be switched off in the preferences settings - then TGrab will create only a single file, that will get updated on each capture).
If no path is indicated, the images are stored in the same folder as TGrab.
