Does SolFS allow path lengths greater than 260 chars?

I read this (https://www.eldos.com/cbfs/articles/7769.php) relating to CBFS but I want to know if SolFS allows path lengths greater than 260 chars?

Take for example a specialist software system that examines images of a disk, where there will be some file paths whose combined name and path are greater than 260 chars. Within the speciliast software all is OK but when the user chooses to export some of these files, it uses the Windows API CreateFileW to export such files (up to 32K long) to the users disk and bypass the 260 limit. But that user then cannot move those exported files normally afterwards, to say another NTFS drive, using Windows Explorer.

I'd like to consider the possibility of using SolFS to allow users to create and mount a SolFS drive, and then they would use their own specialist software as referred to above to export the files from the image to that SolFS mounted drive. The drive could then be unmounted, copied to another drive and passed to someone else, who would use the same utility (that I plan to make) to mount the virtual drive on their own system.

Or is SolFS bound to the same 260 limits?

The SolFS engine has no restrictions for file name length at all, nor 260 characters nor 32K. Such very long filenames may be handled a bit slower because additional disk space is used and additional I/O operations are required. So, App edition of SolFS handles filenames without any restrictions. OS edition and CBFS may have some restrictions.

In the case of SolFS OS edition (Windows) it supports up to 32767 characters in the path. But it is Windows restriction. For details see https://msdn.microsoft.com/en-us/libra...85%29.aspx (the section "Maximum Path Length Limitation").
