Compactor v0.11.3

Added

• Warn when a selected folder contains the DirectStorage runtime (dstorage.dll or dstoragecore.dll).
• Keep the system awake during compression and decompression without forcing the display to remain on.
• Detect the target NTFS cluster size for compression eligibility and projected on-disk allocation.
• Add configurable compression/decompression worker priority: Lowest, Below Normal, Normal, Above Normal, or Highest. Below Normal is the default.

Changed

• LZX Auto concurrency is deliberately conservative: one worker on CPUs with four or fewer physical cores and at most two workers on larger CPUs. An explicit manual thread limit overrides the LZX Auto policy; the HDD single-thread safeguard still applies when enabled.
• Worker priority applies only to compression/decompression threads; the GUI and analysis threads remain at normal priority.
• Analysis uses bounded 4096-file estimation batches instead of allowing the complete candidate set to accumulate before parallel estimation.
• Skipped files retain counts and size totals without retaining every skipped path, reducing memory use on very large scans.
• Displayed projected savings are adjusted for the selected WOF algorithm and rounded to the target volume's cluster size while the eligibility decision continues to use the raw sampled compressibility result.
• Decompression results use the file's actual post-operation on-disk allocation instead of assuming physical size equals logical size.

Fixed

• Compression and decompression now open each active file while allowing readers but denying concurrent writers and deleters, reducing the risk of racing game/application updates during a WOF operation.
• File size and modification time are now read from the already-open protected handle before deciding whether a previous analysis estimate is still reusable, closing the remaining change-between-check-and-open race.
• Correct logical-versus-physical file accounting so sparse/allocation edge cases do not distort folder totals or estimated savings.
• Skip files whose logical length cannot save an NTFS cluster instead of spending analysis time on files that cannot reduce allocation.
• Strengthen target validation: only local NTFS folders are accepted; whole-drive roots, network/UNC paths, the active Windows directory, System Volume Information, root $* directories, root Recovery, and legacy LZNT1-compressed target folders are rejected.
• Correct the GUI allocation breakdown to use actual on-disk bytes for physical categories.
• Repair the v0.11.3 lockfile so existing dependency checksums remain identical to the known-good v0.11.2 lockfile; only the local package version changes.
