550 'filename.ext' cannot be listed

[bigstar]

This command is sent to determine if the file already exists on the FTP server.

It relates to the option in the File Transfer Rules dialog
[ ] Request file size/date prior to transfer

When this setting is checked FlashFXP will send the MLST (if supported) or the SIZE command to determine if the file exists.

Depending on your situation you can disable this feature to speed up FlashFXP.
If the FTP server has multiple users with access to the files then this setting can help prevent uploading over a file that someone in another FTP session might of uploaded after the directory listing was obtained.

Thank you for the quick Answers.

@MxxCon: Sorry but I don't know what the FEAT command is or where to find it or how to give it to Flashfxp.
My version of Flashfxp is the newest, so 4.2.5 build 1813.

@Bigstar: What you are writing could well be the case so I have disabled this option now.

Another question. A couple of years ago, when I uploaded files on a server where no files were present yet, during the upload, I could see the files appearing (not one by one but mostly a block of files because transfers go fast) on the server side window of the FTP program.

This is not the case anymore. Is there an option that I can see the files appearing again or a variable I can put in somewhere?
