Difference between an absolute and a relative path:
- Source folder: C:\
  absolute path: C:\Windows\System32
  relative path: \Windows\System32
- Source folder: C:\Windows
  absolute path: C:\Windows\System32
  relative path: \System32

Filter Actions

Exclude

All files and folders matching a filter are excluded from the copy operation. Example: If you specify the filter *.ini, all files with the .ini extension are filtered, i.e. excluded from the copy operation.

Include

Only files matching a filter are included in the copy operation. Example: If you specify the filter text *.ini only files with the .ini extension are processed during a copy operation. All other files are filtered (= excluded) from the copy operation.

Filter Types

Text (Wildcards)

This filter type allows you to use wildcards in the filter text. For example, the filter text *.exe filters all files with the .exe extension. The filter can be compared with one of the following properties:

File Name
File Path (Absolute)
File Path (Relative)
Folder Name
Folder Path (Absolute)
Folder Path (Relative)

Text

With this filter type, wildcard characters in the filter text are ignored and treated like normal text. For example, the filter text data#1 filters all files or folders named data#1. If you enable the Partial Match option, the filter text only needs to be partially present in a file or folder name. For example, the filter text data#1 filters all files and folders that contain the text data#1 in their name, such as the name 2025_data#1_backup. The filter text can be compared with one of the following properties:

File Name
File Path (Absolute)
File Path (Relative)
Folder Name
Folder Path (Absolute)
Folder Path (Relative)

RegEx

With this filter type you can use regular expressions at the filter text. The filter can be compared with one of the following properties:

File Name
File Path (Absolute)
File Path (Relative)
Folder Name
Folder Path (Absolute)
Folder Path (Relative)

1. Folder Level: C:\Data
2. Folder Level: C:\Data\Backup

Examples when using the filter action Exclude:

With the filter text 1,3 for files, all files in the folder C:\Data and C:\Data\Backup\Windows are excluded from the copy process.
With the filter text 1 for folder, all folders including their contents are excluded in the source folder C:\Data and only the files from the 1st folder level are copied.

Example when using the filter action Include:

With the filter text 2 for files only files from the folder C:\Data\Backup are copied. All files from the 1st & 3rd folder level are excluded from the copying process.

All activated source and target folders, including the 1st folder level, are read in and displayed in 2 opposing tree structures, as in a copy preview. When reading the subfolders, all activated folder filters from the filter list are applied and excluded subfolders are displayed with a filter symbol. Source and target folders that could not be found are displayed with a gray folder icon.
