The free evaluation version lets you try all the features of FolderMill — hot folder–based document conversion and printing software.

Latest release – Version 5.5 (18 September, 2025)

• New supported formats: MD (Markdown, .md), NUMBERS (Apple Numbers, .numbers)
• Convert to Image Action: Ability to preserve CMYK color space when converting PDF to TIFF/JPEG
• Email as a Source: New Enhanced filtering option that handles emails with greater precision. It applies FolderMill’s built-in email filters (such as To:, From:, Subject:, etc.), instead of relying only on the mail server’s filters which may fail to work in some scenarios
• New error handling option if FTP or Email become inaccessible (Hot Folder's Advanced settings → Error handler) allowing to stop Hot Folder processing (Stop rule)
• Fixed a bug with IMAP protocol: previously, attachments sometimes weren't properly detected
• Improved Send to Email Action: Added new option to set BCC (Blind Carbon Copy)
• Print placeholder instead of attachment by file mask: It is now possible to choose which types of file attachments that match a specific file mask must be replaced by a placeholder
• Wait until printer queue is empty: Resumes printing only when the printer queue is empty — for more reliable printer settings recovery
• Consider missing print page range as error: Set FolderMill to not flag an incorrect (non-existent) or missing page range as an error
• Consider missing attachments to print as error: Optionally flag or ignore the absence of file attachments as an error (if Print attachments: Print only attachments is selected)
• New ability to export Hot Folder settings as Flat rule file (*.flat-rule) allows editing "rule" files manually — empowering advanced users and developers
• New Cover Page Designer with real-time preview panel and refined functionality
• New cover page templates
• Added new interval units (hours, days) besides seconds for Rescan period on the Control Panel interface with for optimized Source monitoring
• Added new OCR languages: Chinese Traditional and Arabic
• Backup of data (saving Hot Folders and their settings) is now performed every time during any re-installation of FolderMill, regardless of the program's version
• Ability to move or insert Actions anywhere in the Action Set — cut/copy/paste Actions anywhere in the Set using left or right mouse button for convenience (previously this was only possible via deleting Actions and appending them to the end of the Action Set) 
• Resolved issues with P7M format handling where signatures caused artifacts on the output PDF 
• Improved Filter by color Action: New setting Every page in document has to match the filter criteria, avoiding false positives on single-page files. This prevents an issue when even one-page files always met the conditions which wasn't correct
• Convert to PDF Action: PDF standards (Regular, PDF/A, Password-Protected) are now more easily accessible; it is now on the Action's common settings window
• Convert to PDF Action: New setting to Remove unused objects (enabled by default) allowing to keep or discard some unnecessary objects; by default, it optimizes files by discarding unnecessary elements
• Upload to FTP Action: Fixed an error when handling subfolders in FTP
• Upload to HTTP Action: Added ability to use macros, such as {SrcFileName} (source file name)
• New how-to article: "How to Use Cover Pages to Separate Printed Documents"
• New how-to article: "How to Preserve CMYK Color Space when Converting a PDF to JPEG-CMYK or TIFF-CMYK"
• Information about printer types has been added to the log: network or local
• Information about the number of printed pages has been added to the log
• Error handling mode: if at least one root chain ends with an error, this is now considered an error in the log (new status "Job incomplete")
• If Error handling mode: Stop rule on any error is enabled and an error occurs, the Hot Folder icon will display an error status, with a tooltip showing the most recent file that failed
