Filter invalid characters from filename

[invasion13]

Hi,
with filezilla 3.0 , when i want to ftp from my pvr(KISS DP558) a file named
AUX - Mar 11-09-2007 20_30_21.vob
In my pc folder it appears as "30" (without extension) with a size of 0ko,
and filezilla says the transfert has been successful!
this problem doesnt occur with filezilla 2.2.32
with the same settings(pasv mode and ascii file "auto")
best regards

Please set debug level to 3 in settings dialog and enable raw directory listing. Restart FileZilla and attempt to download the file. Next post the complete contents of the message log here. Please do not leave out parts of the log or otherwise obfuscate the log in any way.

[Tim Kosse]

Actually two problems:
a) Server (or client) behind firewall which blocks the transfers
b) Client needs to filter out invalid characters from filenames, like :

[Alexander Schuch]

Taken from now closed:
[ 1213540 ] Creating illegal filenames

"I would be nice if FileZilla could translate or remove such characters, without miscreating them like this, or like most other file transfer software seem to do; just fail silently and not bother to create the misnamed file at all."

[Alexander Schuch]

Taken from now closed:
[ 587170 ] Convert illegal filename characters

"Rename files, converting characters that would be illegal on the destination host to acceptable characters.

As an example, when transferring a file whose name contains ":" (colon) from unix to a PC running Windows NT, FileZilla truncates the filename just prior to the colon and writes no bytes. It also claims in the status window that the transfer was successful.

Simply converting all such illegal characters to "_" (underscore) would be ok, since that is what some other FTP clients do. If you want to go a step beyond that, you might allow the user to specify the character to use or even allow a mapping table."

[invasion13]

Hi,
i didnt have these worries(and have to rename the files) with filezilla 2.2.32
before and a ftp transfert with "AUX - Mar 11-09-2007 20_30_21.vob"
is successful with version 2.2.32.(i have both the 3.0 and 2.2.32).
regards

[Alexander Schuch]

Taken from now deleted item, which explains the current behaviour of FileZilla 3:
[ 1798271 ] Colons in file names not replaced

"Reproduce: Have four files named '4:30.jpg' through '4:33.jpg', and try transferring them to a Windows machine. The result will be a single empty file with name '4'."

[Alexander Schuch]

Taken from now closed (applies to FileZilla 2):
[ 1656701 ] Colon in directory name not replaced

Make sure invalid characters get replaced in filename *and* in directory name.

[invasion13]

Hi,
i am sorry,
i have understood that ":" isnt allowed in a file name or directory
but why it's working with filezilla 2.2.32:
It is replacing the ":" with "_" that, without any action from my side?
(and so ftp transfert is successful)
Is it a default setting ?
And so why filezilla 3 isnt able to do the same?
regards

[patpowerman2]

The problem with the special characters (like : ) in filenames still appears!

Could you please have a look at that? It prevents to transfer recorded movies to my PC...

[underground78]

I can confirm that the problem is not solved on FileZilla 3, when I download a file named for example "aaaa:bbbb.txt", the file I get is named "bbbb.txt" (but isn't corrupted) ...

[Gerhard Olsson]

Still in 3.1.6 on Vista (Swedish)
Similar bug in FireFox extension FireFTP:
​https://www.mozdev.org/bugs/show_bug.cgi?id=20348

Note: Handled in ftp clients built in to FF/IE

There is some handling for colon, but only fr the first one...

[Gerhard Olsson]

Still in 3.2.0-rc2 on Vista (Swedish)

[underground78]

This bug is still on 3.2.3-rc1 : if you try downloading a file named "aaaa:bbbb.txt", you get a file named "aaaa" with a size of 0Ko ... :s

[CrazyGolem]

The bug is still not resolved on 3.2.4 (2009-04-21).
Downloading files over SFTP, FileZilla does not filter illegal Win32 folder names (e.g.: "blablabla..." that contains trailing dots). It results in a folder that is not accessible by Windows (but still accessible and renamable on others OS like Ubuntu, and when renamed, it becomes accessible in Windows).

FileZilla seems to manage correctly (i.e: trailing dots are removed) folders with only one ending dot in name, or empty folders with more ending dots.

FileZilla can access such folders when downloading (it downloads all files correctly, can add files in it, and so on) but accessing it from the explorer pane of FileZilla doesn't work.

It is a limitation of Windows, not of the file system (in this case NTFS) : ​http://support.microsoft.com/kb/320081/en-us (see Cause 6)

FileZilla on Windows should filter such filenames, or refuse to download them, since Windows Explorer can't manage such files or folders.

Hi!
This posting is only about files having a colon (:) in their names!

The Bug is still there in 3.2.4.1 (tested on Win XP Pro SP3, NTFS). But technically speaking this is NOT a bug of Filezilla but an unexpected behaviour, confusing users.

The cause is not a limitation of Windows or NTFS - it's a feature! This feature is called "alternate data streams" (ADS) and is widely used on Windows.

How to reproduce:
I created a file called AAA:nothing.txt (size 63 kb) on the ftp server (linux). Downloaded it using Filezilla onto a drive formatted with NTFS. Download completes and the file is shown on the LOCAL directory listing with the name AAA:nothing.txt. After refreshing the directory listing in Filezilla the file name is shown only as AAA (just like in Windows Explorer).
Using the command line tool "streams" from Microsoft/Sysinternals you can see this:
D:\>streams A*

Streams v1.56 - Enumerate alternate NTFS data streams
Copyright (C) 1999-2007 Mark Russinovich
Sysinternals - www.sysinternals.com

D:\AAA:

:nothing.txt:$DATA 63000

The file AAA was created with the alternate data stream called "nothing.txt" with the correct file size+data.

Here some links onto this topic:

Hopefully this helps with improving Filezilla :>

Filtering of invalid characters will be implemented in the next version.
