Note: I need this for unit testing the glob(file name pattern matching) functionality on a temporary directory containing temporary files rather than using the actual file system. 回答1: You can use open() with whatever file name you need. e.g. open(name, 'w') Open Or import os import tempfile print 'Building a file name yourself:

问题 I have an application written in Python that's writing large amounts of data to the %TEMP% folder. Oddly, every once and awhile, it dies, returning IOError: [Errno 28] No space left on device . The drive has plenty of free space, %TEMP% is not its own partition, I'm an administrator, and the system has no quotas. Does Windows artificially put some types of limits on the data in %TEMP% ? If not, any ideas on what could be causing this issue? EDIT : Following discussions below, I clarified the

问题 I want to create a temporary file in POSIX shell ( /bin/sh ). I found out that mktemp(1) doens't exist on my AIX box, and according to How portable is mktemp(1)?, it isn't that portable and/or secure anyway.

问题 Using MinGW 7.3.0 on Windows, Hunspell can't load the dictionary files from locations that have non-ASCII characters because of Windows limitations. I've tried everything[1] and I'm now resorting to copying the file to a path without ASCII characters before giving it to Hunspell. What is a good location to copy it to? [1] Windows requires wchar_t support for std::iostream.open() to work right, which MinGW does not implement std::filesystem can solve this, but only available in GCC 8 Hunspell

问题 Where should a windows application store cache data and temporary file data ? I understand that System.Windows.Forms.Application.StartupPath + @"\" + "Cache"; is not a good idea since the program is going to probably be installed in Program Files\MyProgram\ for all users and users may not have access to writing to that folder. 回答1: Use this: System.IO.Path.GetTempPath(); Closely related issue: How to get temporary folder for current user 来源： https://stackoverflow.com/questions/5420234/where
