File Filter

The file filter allows you to exclude specific files from a search operation.

Filter Type

Using the filter types Inclusive and Exclusive, you can define how the filter texts are applied during the search.

• Inclusive
  Only files that match an activated filter text will be considered during the search. For example, if you set the filter text *.ini, then only files with the extension .ini will be considered.
• Exclusive
  All files that match an activated filter text will be excluded from the search. For example, if you set the filter text *.ini, then all files with the extension .ini will be excluded from the search.

Filter List

The filter list contains all existing filter texts for files. Each filter text can be activated for the search operation using its checkbox. To add a new filter, click the File Filter button in the toolbar. A right-click on a filter in the list opens a context menu for editing or deleting a filter.

Filter Texts

The comparison with the filter text is always performed with the file name. If a filter text contains the character \\, then the comparison is performed with the complete file path. By using various wildcards such as * or ?, you have the option to filter multiple files with one filter text. Windows environment variables can also be used in the filter text. You can specify multiple file filters in a filter text by separating them with the character |.

Examples:

• *.txt
• temp.*
• *temp.txt
• temp??.*
• temp.00?
• %USERNAME%.txt
• *\Temp\*.tmp
• C:\Temp\*.ini
• C:\Temp\%Username%.*
• *.bmp|*.jpg|*.jpeg|*.png

Options

• Treat wildcards in filter as text
  With this option, wildcard characters in a filter text are treated as normal text.
• Consider case sensitivity of filters
  With this option, the case sensitivity is considered when comparing a file name with a filter text.

File Properties

• Ignore files with 0 bytes
  With this option, all files with a size of 0 bytes are excluded from the search.
• Exclude files by their size
  With this option, you can exclude files from the search based on their size.
• Exclude files by their date
  With this option, you can exclude files from the search based on their modification or creation date.
