NSF Splitter Features for Lotus Notes Archives
What PCVITA splitter does with an oversized Lotus Notes database, grouped by task.
Loads NSF Files, Folders and Contacts
Add the files you need to divide in one step, protected or not.
Add One or Several NSF Files
Use Add File(s) to browse and select your NSF files in one go.
Add a Folder of NSF Files
Add Folder loads the NSF files stored in a folder, so you skip the file by file selection.
Password Protected and Encrypted Files
Large NSF databases split even when they are password protected or encrypted. Enter your Notes ID password when the tool asks.
Contacts From Names.nsf
Add a separate Names.nsf file and divide your Lotus Notes contacts database into smaller parts.
Archives and Offline Domino Files
Mail archives split like any other NSF file. Copy a Domino server file in offline mode to another location and add the copy.
Splits NSF Files by Size and by Folder
Set the part size yourself or give every folder its own NSF file.
Split by Size in Parts You Set
Enter the Split Size and the tool cuts the NSF file into parts of that size to reduce the file size.
MB or GB Unit
Choose MB for small parts or GB for larger ones in the same Split Size box.
Split by Folder
Folders get their own NSF files. Inbox folder gives inbox.nsf and Outbox folder gives outbox.nsf. Divide those files by size afterward if they are still large.
All Documents Option
Select All Documents to include emails from all folders in the output NSF file.
Splits NSF Files by Date and by Year
Cut a database along time lines and keep every period in its own file.
Split by Date Range
Enter a From date and a To date and the tool filters the NSF file to that range.
Calendar Date or Date Range
Select one date from the calendar or a date range, then click Add.
Added Date Range Table
Every range you add appears in the Added Date Range Table before you start the split.
Split by Year

Keeps Data Intact and Reports Every Split
Check the result on screen and in a report you can save.
Original Attributes and Metadata Kept
Emails keep their attributes and metadata, so file integrity stays the same before and after the split.
Source File Stays Undamaged
NSF Splitter divides your NSF file without damaging or corrupting the source file.
Live Status While the Split Goes
Watch the NSF file being divided while the job is in progress.
Record Count and Split Status
Both values show for every item when the split ends.
Report With Source User
View Report opens the export report in Excel with the splitting details including Source User.
See these options on your own NSF file. Free demo splits 15 items.
Why Large NSF Files Need Splitting
Three limits that HCL documents for Domino databases. PCVITA NSF splitter handles every one differently.
- 1
Databases Stop at a Size Ceiling
HCL states that databases at ODS 53 or higher reach 256 GB on Windows and UNIX. Below ODS 53 the limit is 64 GB. Admin quotas set a lower ceiling. PCVITA splitter divides a big file into parts at the size you set.
- 2
Archive Criteria Follow Age, Not Size
The HCL archive settings page lists Older than, Not accessed in more than, Not modified in more than and With expiration date older than. It lists no size trigger. PCVITA tool splits by size, date range, year range or folder.
- 3
Archiving Cleans the Mail File
HCL describes archiving as copying old documents to an archive database and then deleting or truncating the copies left in the mail file. NSF Splitter divides your NSF file without damaging the source file.
Prepare Before You Split an NSF File
Seven quick checks for a smooth job. Tick them off before you open the splitter.
- Install Lotus Notes on the machine. NSF Splitter needs a Lotus Notes installation to split NSF files.
- Copy Domino server files offline to another location and add the copy. Domino server stays offline during the split.
- Keep the Notes ID password ready. PCVITA tool asks for the case sensitive password before the split starts.
- Install Microsoft .NET Framework 4.5 or above on a Windows machine with 20 MB free disk space and 512 MB RAM.
- Open the splitter as administrator. Windows 10, 8.1, 8, 7 and Vista need Run as Administrator.
- Get a separate Names.nsf file if you want to divide contacts.
- Try the free demo on your own NSF file before you pay. Download the NSF Splitter Tool demo and split 15 items.

| Point | Domino Mail Archive | PCVITA Tool |
|---|---|---|
| What it does | Copies old documents into an archive database | Divides one NSF file into smaller NSF files |
| Criteria | Older than, not accessed, not modified or expiration date | Size, date range, year range or folder |
| Size based split | No size criteria on the HCL settings page | Size parts you set |
| Output | Archive database in an archive folder, name starts with a_ and ends with .NSF | Smaller NSF files in the folder you select |

| Result check | Not listed on the HCL page | Record Count, Split Status and an Excel report |

Archive facts come from Creating an archive criteria settings document (HCL Domino 9.0.1). Size facts come from Setting database size quotas (HCL Domino 11.0.1). Tool facts come from the Specifications and Features sections above.
NSF Size Limit Facts From HCL
- Databases at ODS 53 or higher reach 256 GB on Microsoft Windows and UNIX.
- Databases below ODS 53 stop at 64 GB.
- Database size quotas set the largest size a database can reach. Domino logs a message when a database would exceed its quota.
- Size warning thresholds add an early log message before the quota is hit.
- Split a big NSF file by size or date before it reaches those limits, then keep the smaller NSF files.
Open the Software Guide for the date and year screens that keep every part small.
