We have a website hosted on a VPS, with thousands of largish images, which I have been maintaining with Interarchy via a directory mirror from my desktop. Recently I've encountered a problem when trying to delete image files from the server with Interarchy 10.0.5 ftp client. Selected files are not deleted and Interarchy gives a server error 550 message for each file. Up until now this has worked fine so I'm wondering if the problem could be some kind of server access blocking. Since the directory was mirrored with Interarchy, it's possible Interarchy itself is preventing deletion because I am working in this case from a simple directory listing. VPS support deleted the files for me, but I'd like to know why this is happening. BTW, just remembered that the problem first manifested when I tried to run a mirror and it quit with a case mismatch error on a misnamed file which needed to be deleted. I had deleted prior from my source directory. File had been misnamed but was close to (starting characters identical) the correctly named file in source. If this is the reason it would be a bug in Interarchy so I think another explanation is likely. Any insights appreciated. P S- Would also appreciate recommendations for alternate (preferably free) ftp client, which support told me to try.
