The goal of this document is to outline the technical considerations for supported features in Web Access.
This document has been updated for version 10.1.
Items in a Directory
To provide optimal performance, Nasuni recommends keeping directories under 10,000 items. Depending on the workload, folder listings of 10,000 items should take no more than 20-30 seconds.
Web Access does support folders with up to 128,000 items. For folders containing more than 128,000 items, data might still be returned, up to a maximum of 256,000 items. Any items beyond this limit would not be included in the response.
File and Folder Name Length
File and folder names can be up to 255 bytes long.
Note: This limit is in bytes, not characters. Some characters (like those in UTF-8) might use more than one byte, so the actual number of characters might be less.
Path Length
The maximum length of a path, composed of multiple segments of up to 255 bytes each, is 4000 bytes. The path does not include the share's name.
Valid or Invalid Characters in Folder/File/Paths
Web Access does not allow for the creation of files and folders with special characters in the name such as: ?, <, >, \, :, *, |, ".
If a file or folder name (created outside of Web Access) contains one of these characters, Web Access renders it as a tofu character .
Unicode characters are supported for files and folders, including emojis.
Upload File Size Limits
File uploads are limited to 35 GiB (Gibibytes).
Zip Downloads
Zip file size limits
Multi-file or folder downloads are not available if the uncompressed size would exceed 2 GiB (Gibibytes).
Zip number of files limit
There is a limit of 2000 files in any zip download.
Preview Limitations
Preview File Size Limit
There is a maximum pre-viewable file size limit of 250 MB (Megabytes).
Preview Conversion Timeout Wait
For non-PDF document files, there is a 25 second timeout when waiting for the file conversions to PDF, which is required when previewing such files.
Supported Previewable File Types
The following file types are supported:
Images
Images with the following extensions are supported: jpg, jpeg, gif, bmp, png, svg.
Note: Images with tiff, tif extensions are supported on Safari.
Video
Videos with the following extensions are supported: mp4, m4v, mov, webm.
Note that if the browser doesn’t support the codec used to encode the video it won’t be able to be played natively.

Document
PDF documents (pdf extension) are previewed inline within the browser.
Other document formats are converted to PDF files for previewing: : txt, rtf, doc, docx, dot, dotx, ppt, pptx, pot, potx, xls, xlsx, xlt, xltx, csv, odg, ods, odp, odt, ott, otp, ots, otg. If the conversion takes longer than 25 seconds to appear, a message appears offering you the option of downloading the file.
Documents must be under 250 MB to be previewed.
Shared Item Limits
There are two license levels for Web Access
Basic - Available to all customers
Advanced - Requires a license.
Number of Shared Items
With a Basic license, each user can create at most one shared link per folder or file.
An Advanced license supports up to 250 shared links per folder or file for each user.
Number of Recipients of Email-Shared Items Limit
A default limit of 100 email recipients is imposed for shared links sent via email.
Number of Shared Items Displayed on the Your Shared Items Screen Limit
Up to 10000 shared items are displayed on the Your Shared Items screen (for each user).
OTP Generation Lock Time
A cool-off limit of 30 seconds is in place for how frequently a One Time Password can be requested by a shared link recipient.
