4.3 Extended Information Recovery
R-Studio supports recovery of compressed files, alternative data streams, encrypted files, file security and
extended file attributes. If the R-Studio host OS and the file system of the disk you are going to save file to
support any particular extended information, it will be saved with the file, too. Otherwise, the extended
information will be saved as separate files with the same name as the restored file and extension showing the type
of the extended information. Below is a quick reference for the host OS and file system of the target drive.

4.4 Data Formats
You may enter data in all numerical fields either in sectors or in bytes. If there is no letters are after the number,
R-Studio assumes the numbers are in bytes.
Decimal numbers are entered as they are: 2372354
Hexadecimal numbers are entered as 0x23Fa67 or 23Fa67 hex.
The following case-insensitive notation is possible:
1 gb = 2^30=1073741824 bytes
1 tb = 2^40=1099511627776 bytes
1 eb = 2^50=1125899906842624 bytes
4.5 Data Recovery on HFS/HFS+ File System
When deleting a file, Mac OS X deletes system BTree+ records describing the file. Therefore, it is hard to
recover such file directly. Those records may remain in:
1. The swap file (if the deleted file has been deleted recently).
2. In the journal (if the HFS+ journaling is on, and the deleted file has been CREATED recently)
