I have asked everyone I know about this but noone has a clue so I turn to the high-end segment of my network which has yet to fail me

I have some ascii files on a unix-box that are quite large (4GB total)that I need to transfer to my windows-server to be bulk-imported in to a database on a daily basis. I use basic dos-prompt ftp and when I transfer the ascii-files using ASC transfer mode everything works fine.

However, when I compress the files in tar-format I have to transfer usin BIN to be able to uncompress the file on the recieving end. When I uncompress the tar-file and open up the ascii-files they are "corrupted" in the same way as if I transferred them usin BIN mode directly without the compression.

Any clues on what I can do to work around this...?

untar the files using winzip. winzip has a feature that will convert unix ascii files to windows ascii formatted files. I think it is enabled by default, but if not check around in the preferences.

there are many other utilities that can convert unix ascii to windows, but I find winzip to be the easiest.

also, TAR doesn't really compress. it is just an archive that holds a bunch of files. you would normally combine TAR with GZIP to compress the archive.

a command like the following on your unix/linux environment should do the trick

tar cf - target | gzip -c > target.tgz

I pulled this example from http://www.tech-recipes.com/unix_tips64.html

Sorry for not getting back to you sooner but I have been in the mountains snowboarding since friday

The files are as you say archived using tar and compressed with gzip. I have not yet tried uncompressing with WinZip but I did try with the command line version of 7zip and this is when I got the problems. I'll try winzip and see what happens...thanx
