If you didn't make a backup, you unfortunately don't have a backup. Overwriting a file is even more dicey than deleting it, deleted files may leave partial contents floating around in unallocated disk sectors, overwriting it may actually trash it so there's literally nothing left.
I can't speak for notepad++ though. It might have made temporary files and, given it crashed, not deleted them. Check for temporary files in /tmp/ as well as any recently-modified files under where WINE keeps temp files for Windows and your user (probably ~/.wine/ )
If you want to look contents floating around in raw disk, stop using that disk immediately, boot a livecd, and scan that partition with magicrescue for ASCII text files. It will find text files on your system, potentially in fragments, and save them as numbered files. You'll likely have a ton of files to pick through and sadly aren't guaranteed to find what you want at all.

FLS(1) General Commands Manual FLS(1)
NAME
fls - List file and directory names in a disk image.
SYNOPSIS
fls [-adDFlpruvV] [-m mnt ] [-z zone ] [-f fstype ] [-s seconds ] [-i imgtype ] [-o imgoffset ] [-b dev_sector_size] image [images] [ inode
]
DESCRIPTION
fls lists the files and directory names in the image and can display file names of recently deleted files for the directory using the given
inode. If the inode argument is not given, the inode value for the root directory is used. For example, on an NTFS file system it would be
5 and on a Ext3 file system it would be 2.
The arguments are as follows:
-a Display the "." and ".." directory entries (by default it does not)
-d Display deleted entries only
-D Display directory entries only
-f fstype
The type of file system. Use '-f list' to list the supported file system types. If not given, autodetection methods are used.
-F Display file (all non-directory) entries only.
-l Display file details in long format. The following contents are displayed:
file_type inode file_name mod_time acc_time chg_time cre_time size uid gid
-m mnt Display files in time machine format so that a timeline can be created with mactime(1). The string given as mnt will be
prepended to the file names as the mounting point (for example /usr).
-p Display the full path for each entry. By default it denotes the directory depth on recursive runs with a '+' sign.
-r Recursively display directories. This will not follow deleted directories, because it can't.
-s seconds
The time skew of the original system in seconds. For example, if the original system was 100 seconds slow, this value would be
-100. This is only used if -l or -m are given.
-i imgtype
Identify the type of image file, such as raw or split. Use '-i list' to list the supported types. If not given, autodetection
methods are used.
-o imgoffset
The sector offset where the file system starts in the image.
-b dev_sector_size
The size, in bytes, of the underlying device sectors. If not given, the value in the image format is used (if it exists) or
512-bytes is assumed.
-u Display undeleted entries only
-v Verbose output to stderr.
-V Display version.
-z zone
The ASCII string of the time zone of the original system. For example, EST or GMT. These strings must be defined by your operating
system and may vary.
image [images]
One (or more if split) disk or partition images whose format is given with '-i'.
Once the inode has been determined, the file can be recovered using icat(1) from The Coroners Toolkit. The amount of information recovered
from deleted file entries varies depending on the system. For example, on Linux, a recently deleted file can be easily recovered, while in
Solaris not even the inode can be determined. If you just want to find what file name belongs to an inode, it is easier to use ffind(1).
EXAMPLES
To get a list of all files and directories in an image use:
# fls -r image 2
or just (if no inode is specified, the root directory inode is used):
# fls -r image
To get the full path of deleted files in a given directory:
# fls -d -p image 29
To get the mactime output do:
# fls -m /usr/local image 2
If you have a disk image and the file system starts in sector 63, use:
# fls -o 63 disk-img.dd
If you have a disk image that is split use:
# fls -i "split" -o 63 disk-1.dd disk-2.dd disk-3.dd
