- TMP files can store various sorts of data. Regularly TMP files are simply renamed files of different types. That is the reason it is regularly difficult to open TMP file without realizing what precisely is inside it. How to open Tmp file. TMP files are erased by the working system when they are not being used any more.
- Find out which app created the file; Right-click on the TMP file; Open with on the menu; Pick the corresponding app for this TMP file Temporary files can always be opened by using a notepad; however, it is based on the file type, temporary files may not be human-readable. Step1:-Right-click the.tmp file you want to open. Step2:-Select “Open.”.

Source code:Lib/tempfile.py
This module creates temporary files and directories. It works on allsupported platforms.
TemporaryFile
, NamedTemporaryFile
,TemporaryDirectory
, and SpooledTemporaryFile
are high-levelinterfaces which provide automatic cleanup and can be used ascontext managers. mkstemp()
andmkdtemp()
are lower-level functions which require manual cleanup.All the user-callable functions and constructors take additional arguments whichallow direct control over the location and name of temporary files anddirectories. Files names used by this module include a string ofrandom characters which allows those files to be securely created inshared temporary directories.To maintain backward compatibility, the argument order is somewhat odd; itis recommended to use keyword arguments for clarity.

The module defines the following user-callable items:
tempfile.
TemporaryFile
(mode='w+b', buffering=None, encoding=None, newline=None, suffix=None, prefix=None, dir=None, *, errors=None)¶Return a file-like object that can be used as a temporary storage area.The file is created securely, using the same rules as
mkstemp()
. It will be destroyed as soonas it is closed (including an implicit close when the object is garbagecollected). Under Unix, the directory entry for the file is either not created at all or is removedimmediately after the file is created. Other platforms do not supportthis; your code should not rely on a temporary file created using thisfunction having or not having a visible name in the file system.The resulting object can be used as a context manager (seeExamples). On completion of the context ordestruction of the file object the temporary file will be removedfrom the filesystem.
The mode parameter defaults to
'w+b'
so that the file created canbe read and written without being closed. Binary mode is used so that itbehaves consistently on all platforms without regard for the data that isstored. buffering, encoding, errors and newline are interpreted as foropen()
.The dir, prefix and suffix parameters have the same meaning anddefaults as with
mkstemp()
.The returned object is a true file object on POSIX platforms. On otherplatforms, it is a file-like object whose
file
attribute is theunderlying true file object.The
os.O_TMPFILE
flag is used if it is available and works(Linux-specific, requires Linux kernel 3.11 or later).Raises an auditing event
tempfile.mkstemp
with argument fullpath
.Changed in version 3.5: The
os.O_TMPFILE
flag is now used if available.tempfile.
NamedTemporaryFile
(mode='w+b', buffering=None, encoding=None, newline=None, suffix=None, prefix=None, dir=None, delete=True, *, errors=None)¶This function operates exactly as
TemporaryFile()
does, except thatthe file is guaranteed to have a visible name in the file system (onUnix, the directory entry is not unlinked). That name can be retrievedfrom the name
attribute of the returnedfile-like object. Whether the name can beused to open the file a second time, while the named temporary file isstill open, varies across platforms (it can be so used on Unix; it cannoton Windows NT or later). If delete is true (the default), the file isdeleted as soon as it is closed.The returned object is always a file-like object whose file
attribute is the underlying true file object. This file-like object canbe used in a with
statement, just like a normal file.Raises an auditing event
tempfile.mkstemp
with argument fullpath
.Changed in version 3.8: Added errors parameter.
tempfile.
SpooledTemporaryFile
(max_size=0, mode='w+b', buffering=None, encoding=None, newline=None, suffix=None, prefix=None, dir=None, *, errors=None)¶This function operates exactly as
TemporaryFile()
does, except thatdata is spooled in memory until the file size exceeds max_size, oruntil the file’s fileno()
method is called, at which point thecontents are written to disk and operation proceeds as withTemporaryFile()
.The resulting file has one additional method,
rollover()
, whichcauses the file to roll over to an on-disk file regardless of its size.The returned object is a file-like object whose
_file
attributeis either an io.BytesIO
or io.TextIOWrapper
object(depending on whether binary or text mode was specified) or a true fileobject, depending on whether rollover()
has been called. Thisfile-like object can be used in a with
statement, just likea normal file.Changed in version 3.3: the truncate method now accepts a
size
argument.tempfile.
TemporaryDirectory
(suffix=None, prefix=None, dir=None)¶This function securely creates a temporary directory using the same rules as
mkdtemp()
.The resulting object can be used as a context manager (seeExamples). On completion of the context or destructionof the temporary directory object the newly created temporary directoryand all its contents are removed from the filesystem.Opening Tmp Files Excel
The directory name can be retrieved from the
name
attribute of thereturned object. When the returned object is used as a context manager, thename
will be assigned to the target of the as
clause inthe with
statement, if there is one.The directory can be explicitly cleaned up by calling the
cleanup()
method.Raises an auditing event
tempfile.mkdtemp
with argument fullpath
.New in version 3.2.
tempfile.
mkstemp
(suffix=None, prefix=None, dir=None, text=False)¶Creates a temporary file in the most secure manner possible. There areno race conditions in the file’s creation, assuming that the platformproperly implements the
os.O_EXCL
flag for os.open()
. Thefile is readable and writable only by the creating user ID. If theplatform uses permission bits to indicate whether a file is executable,the file is executable by no one. The file descriptor is not inheritedby child processes.Unlike
TemporaryFile()
, the user of mkstemp()
is responsiblefor deleting the temporary file when done with it.If suffix is not
None
, the file name will end with that suffix,otherwise there will be no suffix. mkstemp()
does not put a dotbetween the file name and the suffix; if you need one, put it at thebeginning of suffix.If prefix is not
None
, the file name will begin with that prefix;otherwise, a default prefix is used. The default is the return value ofgettempprefix()
or gettempprefixb()
, as appropriate.If dir is not
None
, the file will be created in that directory;otherwise, a default directory is used. The default directory is chosenfrom a platform-dependent list, but the user of the application cancontrol the directory location by setting the TMPDIR, TEMP or TMPenvironment variables. There is thus no guarantee that the generatedfilename will have any nice properties, such as not requiring quotingwhen passed to external commands via os.popen()
.If any of suffix, prefix, and dir are not
None
, they must be the same type.If they are bytes, the returned name will be bytes instead of str.If you want to force a bytes return value with otherwise default behavior,pass suffix=b'
.App To Open Tmp Files
If text is specified and true, the file is opened in text mode.Otherwise, (the default) the file is opened in binary mode.
mkstemp()
returns a tuple containing an OS-level handle to an openfile (as would be returned by os.open()
) and the absolute pathnameof that file, in that order.Raises an auditing event
tempfile.mkstemp
with argument fullpath
.Changed in version 3.5: suffix, prefix, and dir may now be supplied in bytes in order toobtain a bytes return value. Prior to this, only str was allowed.suffix and prefix now accept and default to
None
to causean appropriate default value to be used.Changed in version 3.6: The dir parameter now accepts a path-like object.
tempfile.
mkdtemp
(suffix=None, prefix=None, dir=None)¶Creates a temporary directory in the most secure manner possible. Thereare no race conditions in the directory’s creation. The directory isreadable, writable, and searchable only by the creating user ID.
The user of
mkdtemp()
is responsible for deleting the temporarydirectory and its contents when done with it.Software download sites. The prefix, suffix, and dir arguments are the same as for
mkstemp()
.mkdtemp()
returns the absolute pathname of the new directory.Raises an auditing event

tempfile.
gettempdir
()¶Return the name of the directory used for temporary files. Thisdefines the default value for the dir argument to all functionsin this module.
Python searches a standard list of directories to find one whichthe calling user can create files in. The list is:
- The directory named by the
TMPDIR
environment variable. - The directory named by the
TEMP
environment variable. - The directory named by the
TMP
environment variable. - A platform-specific location:
- On Windows, the directories
C:TEMP
,C:TMP
,TEMP
, andTMP
, in that order. - On all other platforms, the directories
/tmp
,/var/tmp
, and/usr/tmp
, in that order.
- As a last resort, the current working directory.
The result of this search is cached, see the description of
tempdir
below.tempfile.
gettempdirb
()¶Same as
gettempdir()
but the return value is in bytes.tempfile.
gettempprefix
()¶Return the filename prefix used to create temporary files. This does notcontain the directory component.
tempfile.
gettempprefixb
()¶Same as
gettempprefix()
but the return value is in bytes.New in version 3.5.
The module uses a global variable to store the name of the directoryused for temporary files returned by
gettempdir()
. It can beset directly to override the selection process, but this is discouraged.All functions in this module take a dir argument which can be usedto specify the directory and this is the recommended approach.tempfile.
tempdir
¶Opening Tmp Files In Word
When set to a value other than
None
, this variable defines thedefault value for the dir argument to the functions defined in thismodule.Opening Tmp Files
If
tempdir
is None
(the default) at any call to any of the abovefunctions except gettempprefix()
it is initialized following thealgorithm described in gettempdir()
.Examples¶
Here are some examples of typical usage of the
tempfile
module:Deprecated functions and variables¶
A historical way to create temporary files was to first generate afile name with the
mktemp()
function and then create a fileusing this name. Unfortunately this is not secure, because a differentprocess may create a file with this name in the time between the callto mktemp()
and the subsequent attempt to create the file by thefirst process. The solution is to combine the two steps and create thefile immediately. This approach is used by mkstemp()
and theother functions described above.tempfile.
mktemp
(suffix=', prefix='tmp', dir=None)¶Deprecated since version 2.3: Use
mkstemp()
instead.Return an absolute pathname of a file that did not exist at the time thecall is made. The prefix, suffix, and dir arguments are similarto those of
mkstemp()
, except that bytes file names, suffix=None
and prefix=None
are not supported.Open Tmp File Online

Use of this function may introduce a security hole in your program. Bythe time you get around to doing anything with the file name it returns,someone else may have beaten you to the punch.

usage canbe replaced easily with NamedTemporaryFile()
, passing it thedelete=False
