It does, both for filename specifically (see below) and for total of path+filename. But recent versions of Windows have increased it to the point where real-life use is unlikely to hit the limit. However, "In the Windows API [for use by applications, as opposed to components of Windows itself], the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character." <https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry> I doubt that file save dialogs are be affected by that, since they're part of Windows, but maybe. Later in the same article, there is a procedure to remove that limitation in the Windows API, if you're in Windows 10 or 11. I hesitate to suggest that Barry try that procedure himself, because it involves editing the Windows Registry. However, anyone who's comfortable with Registry edits could easily follow the directions to do it for him. > If Barry (OP) has been repeatedly opening and working on backups and backups > of backups etc.., is it possible that repeated time-stamps have hit some sort > of string-length limit (either in Win, GC, Gnome-libs or whatever layer)?? > > Last time I was actively using MS for anything regularly, the filename length > limit was 8+3 ... so I'll defer to pretty much anyone's opinion on this! That limit was increased to 254 (or maybe 199) about 20 years ago, with the release of Windows XP. No blame to you for not knowing, if you don't use Windows. <https://stackoverflow.com/questions/265769/maximum-filename-length-in-ntfs-windows-xp-and-windows-vista> Stan Brown Tehachapi, CA, USA https://BrownMath.com _______________________________________________ gnucash-user mailing list gnucash-user@gnucash.org To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user ----- Please remember to CC this list on all your replies.
