As the UKHO FTP site has now been retired, we have made the files that were previously available under the UKHOPublic login on the retired UKHO FTP site available on the File Share Service (https://fss.admiralty.co.uk/).
Please note that new users of the File Share Service will need to register to use the site - a user guide for the File Share Service can be found here: https://customerportal.admiralty.co.uk/knowledgebase/article/KBA-03255/en-us
Below is a guide to how the files are organised on the File Share Service.
Files are available to download for 28 days unless stated otherwise.
AVCS & AIO files

Below is a guide to how the files are organised on the File Share Service.
Files are available to download for 28 days unless stated otherwise.
AVCS & AIO files
The following AVCS files are available on the File Share Service:
- AVCS DVDs 1 and 2 (ISO format)
- AVCS Weekly Exchange Set (zip file format)
- AVCS Update CD (zip file format)
- AIO Update DVD (ISO and zip file format)
We also make a Weekly Exchange Set available for AIO on the File Share Service only. It is named, for example, AIO_S63_Wk39_23_Only.zip.
ADP files
Update Files
The ISO file version of the ADP Update DVD (for example, ADP_WK39_23.iso) is available on the File Share Service on a weekly basis. This ISO contains updates for both ADP and AENP.
Also available is the ADP Update zip file (for example, ADP_WK39_23.zip) which only contains update data for ADP. A search for ADP will return the latest ADP Update files.
Software files
The ADP software installation files for the two most recent versions of ADP are available to download from the File Share Service as either an ISO or a zip file.
A search for Software will return these files.
AENP
Update Files
All e-NP PDF files are available on the File Share Service. When an e-NP has a new edition, the previous edition will be removed at the same time as we make the new PDF available so there is only ever one version of each e-NP available. You can search for the specific e-NP you want by entering, for example, e-NP66A.
The UCFI file (e.g. UCFI2023090.zip) will be available as it is currently on the FTP site each week.
The files that are available in the e-NP\Updates folder on the FTP site are available as a zip file named UCFCYYYYWW.zip e.g. UCFC202339.zip.
Software files
The software files for e-NP Reader v1.3 and v1.4 are available as zip files on the FSS. A search for software will return these files.
ARCS files
Base CDs
Each ARCS Base CD (1-11) is available in both an ISO file and a zip file format. As new versions of the Base CDs are issued, the previous version will be removed at the same time as we make the new file available so there is only ever one version of each Base CD available.
Update CDs
ARCS Updates CDs are available in both an ISO file and a zip file format.
