ok i see now, thanks.

Yes, a list of opened files is kept in memory.

Hmm, ok maybe i remembered the notepad++ ftp plugin. Then it is the only choice to use it by "keep remote directory up to date" as i understand.

and also i am curious about this,
Winscp is downloading the opened files to temp folder and only remember them while software is working. Then after winscp closed, downloaded files are already in temp folder but it doesnt remember them. So does winscp write opened files's names to Ram or another config file while working.

Indeed WinSCP does not remember old files downloaded anyhow.

And it never did.

I am using notepad++ with winscp.
I connect to ftp with winscp and edit files in notepad++. It is ok. After closing both of the softwares, winscp doesnt delete old files, I can see notepad++ after reopening the software, it is ok too. But when i edit this old files, winscp doesnt remember to upload edited files. Only way is to reopen these files with winscp.

i changed temporary directory. And append remote path , append session name, keep temproray copies, options checked. I opened both software with run as admin selection in windows.

i use windows 10.

i know there is "keep remote directoru up to date" command but isnt it possible to remember sessions after closing wincsp.

Before i can do it normally but ş dont know why it doesnt work now.
