Features in Virtual Folders
This topic provides information about specific features you can use to configure virtual folders in ActiveTransfer:
Encryption and Decryption Options for a Virtual Folder
You can define specific file-based encryption and decryption PGP keys for a virtual folder. When files are uploaded or downloaded to the virtual folder through the ActiveTransfer Server, ActiveTransfer encrypts or decrypts the files in the stream. Encrypted files are decrypted only if they are transferred back through ActiveTransfer using the private key or public key that was used to encrypt them.
The encryption and decryption settings are applicable only when a user connects to ActiveTransfer Server and performs an upload or download operation. ActiveTransfer does not use these keys when the virtual folder is used in an action. If you want to use the encryption and decryption keys in an action, create an encryption or decryption task in the action.
When encryption and decryption keys are configured at multiple levels (user, listener, and virtual folder), ActiveTransfer enforces the following order of preference:
1. Users
2. Virtual folders
3. Listeners
For example, if user A accesses port 10 and uploads a file in VFS MN, then ActiveTransfer checks if the encryption or decryption key is available for user A. If no key is available at the user level, then ActiveTransfer checks for the virtual folder settings for a key. If no key is present at the folder level, then ActiveTransfer checks the server level settings for the key.
User, Group, and Role Permission Propagation for a Folder
ActiveTransfer propagates user, role, or group permissions for virtual folders as follows:
If you grant user, role, or group permissions to a parent folder, the user will also have the same permissions to all subfolders.
If you grant a user, role, or group permissions to a subfolder, the user will automatically have the permission to traverse through the parent folders.
You can override the inherited permissions and specify a different set of permissions to a folder for a user, role, or group. These new permissions are then inherited by the subfolders within the folder.
Use of Special Characters in Search
ActiveTransfer allows you to use the following special characters in search strings.
Wildcard Search
Depending on whether you want a broad or narrow search results containing the search strings provided, you can either use an asterisk or question mark as wildcard characters.
*. The asterisk, along with other search characters, gives you all matches that include the search string characters.
Example: The search string *abc.txt gives these results:
kweihdabc.txt, abc.txt, 874abc.txt, 1abc.txt, aabc.txt, _abc.txt
?. The question mark, along with other search string characters, gives you only those matches that include one character in place of the question mark and the other search string characters.
Example: The search string ?abc.txt gives these results:
1abc.txt, aabc.txt, _abc.txt
Exact Match Search
For exact keyword searches, place the search string within single quotation marks.
Example: The search string 'abc.txt' returns only abc.txt as the search result.
