Changing A File Extension

ehm.. you kinda missed a part of this thread |gridley|

http://gnuwin32.sourceforge.net/packages/file.htm

posted by HTRegz after cgkanchi allready attached (an older version of) the app in a previous post..

Indeed I missed it, thanks for pointing me too it.

Tedob1,
I tried what you suggested with the uuencode. Apparantly our servers strip .uue and .txt files. I tried it both ways. Here's a sample of what I got emailed back to me.

Code:

---

Content violation found in email message.
From:
To:
File(s): tshirt-folding.mpeg

Matching filename: *tshirt*folding*.mp*

---

that was for the .uue file, this is what i got for the .txt file i sent

Code:

---

Content violation found in email message.
From:
To:
File(s): mastercard.txt

Matching filename: mastercard*.*

---

These were just test files, to see if i could get through. I guess the best way, at least on my end, is to send with no extension and tell them what to change it to.

just a thought, will some servers allow files to be transfered without an extention... purely for the fact it could be anything??

If it had no extenstion, it would be an useless file !

i think you should read the post above mine copyright... and i ask again, will you be able to transfer if you removed the file extention and left it blank.... on the fact it could be any file...??

Not completely sure why, but if I change a .zip file to .txt file and email it to somebody. Our Groupwise email server does something to the file that corrupts it. I usually just change the .zip's to .jpg or .gif without any problems though.

so, what you are saying is that just about any binary and script on my tux box is useless ??

when u send attached files that can read by smtp "scan" engine as text, such as a .txt file the process its diferent from a image file. Maybe the scan engine corrupts the file trying to "scan" it.

btw if u send to zip file as a .txt, you deserve that it is destroyed... :)

So the point is, to answer the original question:
Yes, files can get corrupted when you change the extension. Make sure to use an extension that email scanners won't mess with and still let through. (if your intension of changing the extension is to get through the email scanners)
