The number of actions that can be undone via the Edit > Undo-Redo commands.
A very high undo level causes greater memory usage if some very large copy/paste operations are performed.
The drag-and-drop operation is treated as a two-step action so the minimum undo level is 2.
Valid range: <2, 100>
Default: 20

The number of processor cores that GS-Base is allowed to use when updating calculated fields (Tools > Update All Calculated Fields) and when filtering records (excluding full-text searches in memo fields).
Valid range: <1, 100>
Default: 2

Specifies the maximum numbers of records a single table can contain. For each running instance GS-Base initially allocates
"maximum numbers of records" * 4 bytes.
If your databases don't contain large numbers of records, you can choose some small limit to save memory.
This setting doesn't affect the database file format. After increasing the limit, any existing database can be expanded further up to the new limit. Available values:

• 64 K (65,536)
• 1 M (1,048,576)
• 12 K (12,582,912 default)
• 32 M (33,554,432)
• 64 M (67,108,864)
• 128 M (134,217,728)
• 256 M (268,435,456)

If a given database/files contains more records than the current GS-Base limit allows, a respective warning message is displayed.

Specifies the default filter type for text fields. This filter type will be initially set in the Search dialog box.
Default: Regular Expression

Specifies a function that will be used by each new or existing pivot table that doesn't have any data field defined.
The default count function results in counting all subsequent values of the specified row field(s).
Default: Count

Specifies the period of (user) inactivity after which GS-Base will automatically save the open database (if it's modified).
Default: Never

Specifies the period of (user) inactivity after which GS-Base will automatically close the open database. Modified databases are saved before closing.
Default: Never

Specifies whether (and how) to scroll the current table cell after you finish editing and press Enter.
Default: No action

Specifies the default file extension (either *.zip or *.gsb). GS-Base uses that extension when creating and saving new databases/files. Existing files are handled the same way, regardless of their extensions and the changes of that parameter.

Choosing the *.gsb extension enables you to register it in the Windows registry and open databases double-clicking them. The only disadvantage is that you can't view the zip contents using File Manager until you rename it to a *.zip file.
You can register the *.gsb file type in Windows and associate it with GS-Base using the Settings > Register GS-Base *.gsb File Type command. The corresponding Settings > Unregister... command removes all registry entries created during the registration.
Note: To use those commands you must start GS-Base as an administrator (e.g. right-click the GS-Base desktop shortcut and choose the "Run As Administrator" command).

Choosing the *.zip extension enables you to use File Manager to view/edit/browse text tables contained in a given database. In general, it might be helpful only if you're planning to perform some additional text (pre-)processing of these tables with external software or if you're planning to drag-and-drop text files/tables e.g. to quickly create some initial collections of tables manually, without GS-Base.
The disadvantage is that if a database contains a large number of inserted objects/images/memos, Windows will considerably slow down when indexing such zip files. Also, you can't open *.zip files in GS-Base double-clicking such files.

Default: *.zip

Specifies the folder displayed in the Open File dialog box when you open it for the first time (after launching GS-Base).
Default: Empty

If you insert some link *.lnk files into Images/Files fields and later change the location of the target objects that the links are connected to, you can "overwrite" such broken links globally specifying that path.
Default: Empty

Specifies the list of file types (stored in Images/Files fields) that will be saved in the database zip file without compression. The list should contain file types that contain already compressed data. This can improve loading/saving times without worsening the overall compression factor.
Enter the extensions in the *.ext1;*.ext2;... form.
Default: *.png;*.jpg;*.gif;*.pdf;*.zip;*.ods

If you manually drag-and-drop any files to a given database zip file, GS-Base will detect such files and show the list of them.
If the option is off, GS-Base will silently load and save back such unused files.
Default: On

If this option is checked, GS-Base will be displaying a progress dialog box when opening or saving all files. The progress dialog box contains information about the opening/saving process and enables your to cancel it at any time.
Default: On

If this option is checked, after opening a text, xBase or html file GS-Base will resize (used) columns to fit the widths to the field/column contents.
Selecting this option will slow down opening very large files. To speed up this resizing procedure, increase the Number of CPUs value.
Default: Off

If this option is checked, after opening a text, xBase or html file GS-Base will resize (used) rows to fit the heights to the multiline field/column contents. Checking this option is useful only if some field data may contain new-line characters (CR/LF). If Auto-fit column widths is not selected, this option is disabled.
Selecting this option will slow down opening very large files. To speed up this resizing procedure, increase the Number of CPUs value.
Default: Off

Specifies the opacity of all dialog boxes displayed by GS-Base. Decreasing this value means making the windows more transparent.
Valid range: <10, 100>
Default: 100% (no transparency)

Specifies the default font name. The font specified here will be used by database tables, forms, binary edit windows and pivot tables.
Default: Arial

Check this option to use the date-time picker control instead of the plain edit control.
This options applies to text fields that are formatted using one of the standard Date styles (not custom style patterns) and that don't use the drop-down list functionality.
Default: On

If this option is unchecked, trying to edit (e.g. by pressing Enter, double-clicking or pressing any character/number key) a Long Text or Images/Files field will open the LongText or Images/Files view pane to enable users to view/edit the contents.

If this option is checked, trying to edit a Long Text or Images/Files field will open an application associated with a given file/contents type. Choosing the "Save" command in that application will automatically update the data in GS-Base.
Depending on how that edit action is initiated, the following additional functionality is supported:

• pressing a digit key opens either the text or the n-th (1...9) object for editing
• pressing a letter key prints either the text or the n-th (a...z) object

Default: Off

If this option is unchecked, the table/form fields related to the Long Text and Images/Files fields will be displaying text containing the number of files, the total size and the last modification date/time. (If the Images/Files contains some shortcuts to external files, only the number of files is displayed as the label.)

If this option is checked, the table/form fields related to the Long Text and Images/Files fields will be displaying the contained images or file icons with optional labels containing (similarly optional) file names, sizes and the last modification dates/times.

Default: Off

Specifies whether images and files (icons) in tables/forms should be displayed along with their general file information which includes the file name, size and the last modification date/time.
Default: On

Specifies whether images and files (icons) in tables/forms should be displayed as thumbnails of the specified size.
Default: Off

Text entered in the Long Text fields is saved in the plain UTF-8 *.txt text format rather than in the rich text *.rtf format.
Using plain text may noticeably reduce memory usage if there is a very large number of Long Text entries in the database zip file.
Changing this option affect newly entered or edited data only. Older entries remain in the previous format until they are edited.
Default: Off

Text displayed in the Long Text fields is wrapped according to the width of the view pane.
Default: On

By default, after loading LongText fields the beginning of the text displayed.
If you check this option, the text cursor will be automatically positioned at the bottom of the text.
Default: Off

Specifies whether images and files (icons) in Images/Files fields should be displayed along with their general file information which includes the file name, size and the last modification date.
Default: On

Specifies whether images and files (icons) in Images/Files fields should be displayed as thumbnails of the specified size.
Default: Off
