From: drodrig on 12 Aug 2010 07:49 A python script I use to backup files on a Windows 2003 server occasionally fails to retrieve the size of a file with a question mark in the name. The exception I get is "OSError #123 The filename, directory name, or volume label syntax is incorrect". I realize that technically a question mark in the name of a file on Windows is illegal, but nevertheless these files exist on the file system. It seems that they are created by Office 2007 Word, for the most part. The line that fails is: os.path.getsize(source) Where source is the full path to the file with the question mark in it's name. Any idea how to retrieve the file's size? Also, I imagine that after I overcome this hurdle, I'll need help finding a way to copy the file (assuming copy2() doesn't work). I've tried escaping the question mark ("\\?"). Same result. Although I could use the Windows "dir" command, parsing the results to find the size of the file then use the Windows "copy" command, I'd rather stay away from this type of solution. Any help is appreciated!

I'm not aware of any way to get a question mark into a file name; even using the file namespace prefix \\?\ doesn't allow it as far as I can tell. Where are you seeing the question mark? Is it possible it's a placeholder for an unprintable character rather than an actual question mark? TJG

If "?" is a placeholder for an unprintable character you can try view real file name in IDLE: import glob print glob.glob(u'e:/full/path/to/file?') In path to file you must instead question use wild "?". Will be printed all like files. ----------------------------- Under Windows I too have similar problem: windows sometimes (from any programs - e.g. Firefox) save files with wrong names, but later do not manipulate with it. |
