What is the full build version of QlikView Server (i.e. 12.30.20300)?
You definitely don't want to remove the .TShared/.Meta files, as those are vital to the end user experience. See article "What is a Shared/TShared file?" for details on the TShared files; and article "Meta files - General information" for details on the Meta files. Article "What is stored in which QlikView files?" has details on these files as well as .QVW and .PGO files in case you need more information.
You can configure Publisher to retain a specific amount of days of reload/distribution tasks; among other values. See article "QlikView Management Service Publisher Related Configuration Settings for Best Practices and potentia..." for more details.
Do you utilize the QlikView Governance Dashboard? A popular strategy is to use the QVGD and archive the logs once they have been incorporated in. The QVGD used an incremental update to QVDs and then loads from these QVDs, so once the data has been incorporated into the QVGD, it is safe to archive the QVS/QDS logs.
