File name length in Windows 7

What is the max length of the drive+folders+fileName in Windows 7??
Experimentally I get 219 characters but answers on the web seem to indcate the older 250-260 length. If mine are too long I get a popup window saying "XXX could not be found. Check the spelling of the file name, and verify that the file location is correct"
(where XXX is the full name). This message is even wierd as I just double clicked on the file itself - in this case an XLS file.

For the detail information regarding the limitation, please refer:

  • File Name Length

    Hi All,
    While down loading .csv file, i can get my file name length dynamicallly upto 157 bytes but not getting more than that.
    I have a requirement to download very long file name. Can any one please suggest me a good solution?.
    My code is
    response.setContentType(contentType);
                        response.setCharacterEncoding("WINDOWS-932");
                        response.setHeader("Content-Disposition",
                                  "attachment; filename="
                                            + URLEncoder.encode(fileName, "UTF-8"));-vignesh

    It seems there is no restrictions in filename's maxlength.
    However, if you check the section 2.3 of this link
    [http://www.faqs.org/rfcs/rfc2183.html|http://www.faqs.org/rfcs/rfc2183.html]
    It says:
    It is important that the receiving MUA not blindly use the suggested
    filename.  The suggested filename SHOULD be checked
    (and possibly changed) to see that it conforms to local filesystem conventions,
    does not overwrite an existing file, and does not present a security problem
    (see Security Considerations below).I tried to test filename's maxlength with different browsers and found that results differ with browsers.
    The HTTP response header nevertheless contained the full filename.
    Above all, IMO avoiding long filename is the best solution.

  • File name length causing problems

    I want to use my iPod suffle as a data transfer device as well as a MP3 player and am havign real problems copying folders onto it from my iBook or my desktop G4. Is it the file name lengths that are the pprblem (that's certainly the error message I get sometimes). Or the volume of data that I am trying to copy in one hit (400MB-worth)?

  • My Logic file name length changed

    For some reason, Logic started limiting my file name lengths to 31 characters.  This was never an issue before.  I could always use much longer names.  About a week ago, for no apparent reason, it started limiting the length and truncating the names to only 31 characters. Anyone know if this is a bug or is there a setting somewhere that i don't know about.   I'm on OSX 10.6.8.  There is no problem with creating long file names outside of Logic 9.0.0

    This has always been so in Logic. It never suddenly "started"...
    But it was fixed in version 9.1.0, which came out
    almost three years ago
    and is a free update for every LP 9 owner...
    You really should update, there's no reason not to. If you're on a PPC (G4 or G5), you can only go to 9.0.2 (still worth it), if on an Intel Mac (2006 and later), you can go to 9.1.8; this will improve things for you, and also end the 31 charachter limit, which was an atavism.

  • FM for get a PC File Name in a window

    Hi
    Does somebody can help me, i need to call a FM wich shows a window for enter a PC File Name (with F4 browse for windows).
    I do not refer to FM 'F4_FILENAME'  wich we use when we have a file_name field in screen and we use when user press F4 ; instead i need to call a window with the file_name field for the user enters the file name.
    Doe somebody knows some FM wich i can use ?
    Regards
    Frank

    Hi everybody
    I'm going to try to explain; i refer this:
    I have a report wich is generated of course after the user fills the selection screen with the data desaired.  In this report list i have a button wich make some process;  when the user press that button, i need appears a popu window asking for a file name.
    That is, i do not refer to FM wich calls the browse window for select a file name  (like F4_FILENAME), instead i refer to some FM wich calls a popup window asking for the file name for user can write the file name in the input field, and that input field has the F4 help for users can select the file name instead to write it.
    I hope i explained well.
    I search with 'filename' and 'file_name' in SE37 but there are a lot of FM's  and i really don't find the right FM, does somebody knows a FM wich i can use ?
    Thanks a lot.

    Run this short script

    set texte to ""
    repeat with n in theNames
    --set n to n as text
    set texte to texte & n & return
    repeat with i from 1 to count of n
    set texte to texte & (ASCII number of character i of n) & " , "

    if exists file rapport of p2d then delete file rapport of p2d
    set theRapport to (make new file at p2d with properties {name:rapport})
    end tell
    write texte to (theRapport as alias) starting at 1
    navigate to the folder whose list seems curious.
    You will get a file named "the characters.txt" on the desktop.
    It will show the code of every character embedded in fileNames.
    My guess is that there are some control characters which aren't treated the same by the open dialog and by the Finder.

  • I keep getting this message "A dublicate file name was specified Windows"

    I've tried everything, this has been going on for months, and now I really need help.
    I just bought an album on itunes, had to send it to myself as a gift, to make it work. It did, but now I can't download it, because I keep getting this error: "A dublicate file name was specified".
    I'm using windows 7.
    I really hope someone can help me. The support wasn't very helpful....

    Hmm, I'm most familiar with that message in the context of syncing devices when it usual means a problem with the iPod Photo Cache. Any chance of a screenshot of the error message? What exactly do you do before it appears?
    Also try this post from b noir, he seems to know most about quirkly iTunes for Windows installs. It may be we need to track down another of his posts that covers how to completely remove iTunes and all other traces of Apple software before reinstalling.

  • Export File Names from Finder Window...

    I want to export all the file names in a finder window to a file that I can use in Excel (txt, csv, etc.). Can I do this directly from the finder window somehow?

    The answer just above is excellent.
    One additional point which might assist when importing into a spreadsheet.
    If you use a simple naming convention which I developed about 6 years ago for exactly this purpose, you can sort on various features of documents, etc.
    The name of each file is:
    International date,originator,receiver,subject
    This structure looks like this:
    2008-09-12,dwc,you,naming files for spreadsheet use
    THis allows for automatic date sorting or date structuring of files chronologically
    It allows one to know who or what was the source of the document
    It allows one to know to whom it was sent
    and it allows a brief subject with keywords
    More important, because commas are used to separate the fields, they can
    be used as delimiters when importing the text file into a spreadsheet, thus allowing far greater sorting capabilities.
    Best wishes,

  • What is the file name crdb_jdbc.dll(Windows) equivalent to Linux?

    Hi,
    What is the equivalent file name of crdb_jdbc.dll for linux connection info for database?

    It's crdb_jdbc.dll.
    Within the connection info, the name of the DLL specifies the connectivity driver type, that just so happens to correspond to the specific DLL file for that driver for Crystal Reports C++ engine on Windows. For other deployments and engines (such as CRJ), it gets the right one if you specify crdb_jdbc.dll.

  • File Name and Path Length Limitations

    Hi guys,
    We are migrating our Novell NSS Linus File server to Window File server 2008 R2, we do have many directories and files, so of the file names length quite long, is there any tools can be used to identify these files?
    thx

    So you want to validate the file name length in the Novell server? 
    If so, I think it is better to post this question in the Novell forum.

  • Sorting string like windows file name sorting

    Hi everybody, I have a simple question.
    I was trying to sort some file name in java
    Let say we have a list of string which are :
    1.txt
    a.txt
    2.txt
    11.txt
    a(1).txt
    a(11).txt
    a(2).txt
    If i convert those strings as file names, and sort it by file name in the windows explorer the result is
    1.txt
    2.txt
    11.txt
    a(1).txt
    a(2).txt
    a(11).txt
    a.txt
    But if i enter those strings into an Arraylist and use Arrays.sort or Collections.sort, the result is
    1.txt
    11.txt
    2.txt
    a(1).txt
    a(11).txt
    a(2).txt
    a.txt
    Is there a way to achieve the string sort similar to windows rather than aplhabetically like the default sort of Arrays/Collection.
    I have done some searching but only found problem regarding to different language character sorting which can be achieved using Collator but this was not my case. Has anybody encounter this issue ?
    Any help is greatly appreciated

  • Invalid File Name Errors when syncing to Ipod

    Ever since an update last fall I have been getting Invalid file name errors when I try to sync my ipod. A window would pop up saying "Windows could not copy 'SONGNAME' to the iPod 'IPODNAME' because an unkown error occurred (-37)." I would press OK and another window would immediately pop up that would say, "Attempting to copy to the disk 'IPODNAME' failed. the file name is invalid or too long."
    The windows would keep popping up countless times until the sync would just seem to time out and stop.
    The problem songs would have no problem playing in iTunes.
    Prior to the update this did not happen. No new songs were added around this time and nothing was changed to my file directory structure. I was too busy to troubleshoot this problem at the time and hoped that another update would fix it. Well, here I am many months and updates later and still no fix. After fiddling with iTunes and resetting my Ipod multiple times (goodbye saved angry bird games)I have found out that:
    1. By writing down the file name when the error windows pop up I can get a partial list of the problem file names. I could not get a complete list of the problem files because the sync would time out before a full list could be compiled (the list appears to be in the hundreds).
    2. If I changed the name of the file by adding OR deleting one character, remapping the song in itunes, the song would then sync properly.
    3. If I changed the name of the file, remapped the location of the file within iTunes, changed the name of the file BACK to the original name that iTunes supposedly had a problem with, and then remapped the location of the song within iTunes, the song would then sync properly
    4. If I moved the song to a different directory without changing the file name, remapped the song within iTunes, the song would sync properly.
    5. If I moved the song to a different directory without changing the file name, remapped the song within iTunes, moved the file BACK to the original directory, remapped the song again, the song would sync properly.
    6. If I renamed the file and then named it back to the original file name WITHOUT remapping the file location in iTunes, the song would still not sync properly
    7. If I moved the file into a different directory and then back again without remapping the file location, the song would still not sync properly.
    8. Changing or deleting the tags has no effect at all.
    9. File name lengths are already under 200 characters and there are no special characters used.
    So, to sum up, I have found out a way to fix the issue. The problem is, that there are hundreds of songs that appear to be affected and renaming or moving every single one individually and then remapping is extremely inefficient and ignores the cause of the problem. I also did not want to delete the itunes library and then add all of the songs back in because I have many custom playlists that I have spent hours creating and I do not want to delete them.
    Is there a better way to fix the problem? Especially if someone knows the root cause?

    I got a procmon log file and examined it. I have the file and I could also provide you with that or screenshots of it.
    There is nothing unusual about it. I can see entires in which CR has successfully opened the report and has cached in a c:\windows\temp.
    However there is one or two non-successful entries that may be related, especially that examining the stack trace brings us to a call to get_ProductLocaleID():
    - A call to read reg entry HKU\S-1-5-20\Software\Business Objects\Suite 12.0\Crystal Reports\Locale fails with NAME NOT FOUND.
    - immediately after that and from the same process (w3wp.ex) there is a call to open directory "c:\" which is logged as ACCESS DENIED.
    Any subsequent unsuccessful calls seem to be results of exception handling in the debug code.
    Does this point to any setup issues with CR? We always run the redistributable x86 runtime when installing it.

  • File name punctuation WILL cause MP3 and DVD burn errors – workaround?

    OK, I’ve seen TONS of questions about problems burning MP3 format CDs and DVD. I’ve been having this problem for quite a while and today I just got ****** off enough to do some deep research. I seek to share my finding and suggestions for work arounds.
    THE PROBLEM
    iTunes can burn regular CDs since the song file name is not actually put on the CD. The CD or DVD burner work for burning audio discs and with other applications. All the burn preferences are set correctly and have been validated. But when you attempt to burn an MP3 CD or DVD (for backup, transfer or for player that play MP3 discs), iTunes may do the following:
    Checking media (iTunes will ask: “You have inserted a DVD. Are you sure you want to create a Data DVD? answer yes, it’s a blank DVD disc in a working DVD burner)
    Checking playlist
    Burning disc… initializing
    "The attempt to burn a disc failed. An unknown error occurred (xxxx).”
    THE CAUSE
    Many times the error is due to song, album or artist names with unacceptable punctuation in them. iTunes does not tell you why and the error message and Google searches and Apple support/discussion forum details are sketchy… but in most cases its “illegal” punctuation in the song name, artist or album. I isolated at lest the apostrophe ‘ there are probably other illegal name punctuations too.
    The cause my be explained by Apple following ISO or Joliet file name specifications or file name length specifications for CD or DVD discs. But since this appears to be undocumented (to the iTunes user) there is a need to understand the restrictions to allow error free disc burning.
    THE CHALLENGE
    Even if the playlist name does not have punctuation, if ANY playlist song name/artist/album does, the DVD burn will fail. Removing the offending songs from the playlists results in a successful burn but hey, I WANT those other songs too!
    POSSIBLE WORK AROUNDS
    Changing actual song file name – even if you change the name in iTunes (Get Info, Info, change name, artist, album) the actual song file names are not updated and continue to have the punctuation error resulting in a burn failure.
    It appears that the actual file name needs to be changed. This can be a challenge. If you change only the file name you need to add modified file back into iTunes and the old file link is now broken. This is a bigger problem if that song file is in multiple playlists (the old ones are broken and the new one needs to be substituted). This is a REAL problem if you have 2,800 songs with an ‘ in them (like I do).
    LETS WORK TOGETHER AND SHARE RESULTS
    I’ve seen many, many unanswered questions about iTunes CD and DVD burning problems that will likely be solved if we can collectively develop and document a workaround. So, here is
    THE QUESTION
    What is the best way to rename (or retag) MP3 song files to eliminate punctuation and update iTunes and playlists so these songs can be burned to CD or DVD without violating the undocumented illegal punctuation restriction? The work around may differ for OS X vs Windows users so help on both would be appreciated.
    Thank you all in advance for your help!

    been searching myself to create my own cdg for use in universal karaoke players. Kjams appears to offer the most hope for all I want to do. although there's something new now called Aria which promises to do a bunch of stuff for 79 $. Otherwise, all that I want to do as listed by the original poster, would cost me Kjams lite, plus the burn plug in is extra, plus I'd need the kjams producer as I would be building a cdg by adding the synced lyrics to something I've removed the vocal from, on Audacity program. if I go with Kjams, those 3 softwares, it will cost me 150, while I'm so jealous all those PC karaoke singers have free software for karaoke they can download.
    I've been buying my cdg discs at 1.99 a pop, but they don't have special songs I want to perform. Aria for Mac might just do it all but I don't need the "scratch" sound they are pushing. that makes me steer away from the software.
    experimenting with the Imac 10.6 idvd movie quicktime might work. I made a few cdg but have not tried them in the club karaoke machine yet. I added the lyrics to tuneprompter which is a free software that lets you add and sync the lyrics to the music with the spacebar. thats fun. but it's all in experimental thing so far. I know Kjams does not let you add lyrics and sync them yourself. you are supposed to import cdg to kjams that are already available and pay for them. in this case I want to find my own special tunes. good luck to you. there's one other thing but it's expensive. buying software which turns your mac into a windows platform by partiioning it and you start up in one or the other. that's also about 100-150 software.
