Using SyncBackPro > Expert Mode

There are settings to not compress certain types of files, and there are settings to only use high compression on certain file types, there are also settings to use low compression levels on certain file types. For example, .docx files are already compressed so there is no point trying to waste time compressing them further.

If the compression level is already set to the lowest level, then these settings cannot be used and are ignored.

To add a file type, click the Add button (or press Ctrl-A), and to remove a file type, select it (or several) in the list and click the Remove button (or press the Del key).

When using certain compression situations, the low compression setting cannot be used. For example, if you are compressing all files to a single Zip file and are using Deflated, Deflated64, Burrows Wheeler, BZip2 or LZMA compression, then low compression cannot be used. However, if you use LZMA2, XZ, Standard, or compress each file to its own Zip file, or enable the setting to encrypt and compress the filenames and details, then low compression can be used.

If a file is stored using low compression, the variable %LOWCOMPTOTAL% is incremented. The log file will also state the total number of files that were compressed with low compression.
