The table below shows the results of using different compression methods and levels with an example file (the file text8 was used) and SyncBackPro V7. The example file is text (not binary) and has an uncompressed size of 100,000,000 bytes.All the compression methods (except for BWT) are compatible with various compression utilities, e.g. WinZip, 7zip, etc. Only SyncBackSE/Pro can open BWT files. Only SyncBackPro (not SyncBackSE or SyncBackFree or the old V3 freeware) can create BZip2 and LZMA files.
Important: High compression levels, especially when used with LZMA, use a large amount of memory. You may experience Out of memory errors with some files, especially larger ones. To reduce memory usage you must reduce the compression level.
