## Data Recovery

Attention! If files are recovered incorrectly or there are other problems make sure you are using a legal software copy.

Attention! Do not recover to the same partition which contains source data to recover. It is highly recommended to recover data to another physical device. You may recover to another partition of the same device only if you are sure that source and destination partitions don't overlap and device has no physical problems. Do not load system or run program from the partition where data to recover is located.

Before data recovery you should find and open volume. The recovery results depend on results of the volume search and which volume is opened.

To recover all found files (including lost and removed files and NTFS altstreams) you should open virtual directory [All Found + Reconstruction] in the File Panel. This is also required for auto unmarking items during group recovery.

Free Edition supports recovery of up to 4000 files from the current panel only.

### Dialog Box "Recover"

#### Button "Size"

Calculate size of the data to recover. Global indicator of recovery process is working if the size is calculated. You should not calculate the size to avoid unnecessary device load on devices with bad sectors.

#### Button "List"

Save list of files selected for recovery to a file.

#### "Deleted" files

Recover files marked as "deleted" (see File Panel). If the option is not selected "deleted" files won't be recovered regardless the selection state.

#### Checkbox "Include Found"

Recover files marked as "found" (see File Panel). If the option is not checked "found" files won't be recovered regardless the selection state.

#### Checkbox "Include NTFS altstreams" (Professional Edition only)

Recover NTFS alternate data streams (Alt. stream name and file name are separated by a colon, i.e. FileName:StreamName).

#### Create report (Professional Edition only)

Save recovery report to a file. List files and directories, log file I/O errors, calculate checksums CRC32, MD5, SHA1.

#### File filter

Define name masks (semicolon separated) to recover matching files only. Wildcards "*" and "?" may be used. Exclusion masks may be also defined by prepending a backslash "\". Masks at the beginning have a priority. E.g. the name abc.tmp matches a*;\*.tmp and does not match \*.tmp;a*.

#### File size limits

Filter files by size. Use 0 (zero) as a second value if you wish to set a lower limit only.

### Additional Issues

#### Checkbox "Unicode names"

The option is set if there is Unicode support in OS, otherwise symbols outside the selected code page must be transliterated or substituted (see Locales). Unavailable in DOS.

#### Recover to a FAT formatted volume, checkbox "Split large files"

FAT volumes do not support files greater than 4GB (or sometimes 2GB). Larger files may be split during recovery upon a request if OS properly reports (which is not always the case) or if the option Split large files is used (preferable). Later you may merge file parts on another disk by using the system utility copy /b part1 + part2 + part3 result, for example. Pure DOS supports only FAT volumes.

#### File names in DOS, checkbox "Substitute names"

Without special drivers long files names are not supported under DOS. Option Substitute names allows name substitution during recovery. File LRENAME.BAT is being created in the destination folder for backward renaming. To restore original file names load OS Windows, go to the destination folder and execute the file LRENAME.BAT. An appropriate OEM code page must be selected when working in DOS in order to restore national symbols correctly. Unicode symbols outside the selected code page will be transliterated or substituted.

You may add the parameter substnamesutf8=1 or use the option utf-8 to create LRENAME.BAT in the utf-8 format fully supporting Unicode regardless the selected code page. Utf-8 format is supported in Windows 7 and higher.

#### Paths longer than 259 symbols under Windows NT+

In order to recover paths which are longer than 259 symbols you should manually prepend the destination directory name with a prefix \\?\, e.g.: \\?\C:\. Such long paths may be inaccessible for standard programs such as Explorer ("My Computer").

#### Name Duplicate Handling

During recovery there may be name duplicates due to finding different versions of the same file, different links to the same file, or due to erroneous merging of directories.

If a file or directory with the same name is being recovered you are prompted to choose how to handle the duplicates. It is possible to rename the object manually by entering name or to choose auto renaming or skipping all subsequent objects. It is also possible to merge directories with same names.

There is a threshold number of renaming for a single object after which there will be a second request for a desired action when the threshold is exceeded. Parameters maxfilerenames= and maxdirrenames= are used as threshold numbers by default.

Determining name duplicates is working on the base of destination file system. Name handling is not working if name substitution is used under DOS.
