Quick fix: Use xcopy with /k flag (keep attributes). Better: use robocopy instead, which preserves timestamps by default. Example: robocopy C:\Source D:\Backup /e /copy:DAT /dcopy:T. This copies all files including subdirectories, preserves Data, Attributes, Timestamps for files, and copies directory timestamps. Modern recommendation: robocopy over xcopy. Standard copy command and File Explorer drag-drop reset file … Read more
Quick fix: Use robocopy with the right flags instead of File Explorer drag-and-drop. robocopy “Source” “Dest” /e /copy:DAT /dcopy:T. /copy:DAT copies Data + Attributes + Timestamps. /dcopy:T copies directory timestamps. File Explorer copies often set Modified to current time, Created to copy time. robocopy preserves originals. File Explorer’s default copy method changes Created date to … Read more

Quick fix: Junctions (mklink /J) work for directories only on the same volume. Symbolic links (mklink /D or /file with mklink) work cross-volume, even for files. Symlinks need Admin rights (or Developer Mode). Junctions don’t require admin. Use junction for local dir aliases, symlink for cross-drive / file targets. Both junctions and symbolic links are … Read more
Quick fix: Open Command Prompt as Admin (or enable Developer Mode for non-admin). Run: mklink “C:\Link\Path” “D:\Actual\Target” for file link. Add /D flag for directory link: mklink /D “C:\Folder” “D:\Target”. Add /J for junction (directories, same volume only, no admin needed): mklink /J “C:\Junction” “D:\Target”. mklink creates symbolic links and junctions on NTFS. Useful for: … Read more

Quick fix: Already-compressed files (.zip, .jpg, .mp4, .pdf-with-images) don’t compress further. Text files, .docx (XML inside), uncompressed images (.bmp, .png) compress 50-90%. For best compression: use 7-Zip with LZMA2 algorithm at maximum compression level. For .zip files: only metadata compression, not contents. Compression effectiveness varies wildly by file type. Some compress 90%, some 0%. Reason: … Read more
